“Kites that swim sublime
In the still repeated circles, screaming loud.”
These words are equally appropriate to the kites of the sea.
I have watched, until my eyes grew tired, kites floating in circles in
the thin atmosphere, with scarce a movement of the pinions; I have seen
gulls keeping pace with a steamer without as much as a quiver of their
wings. In each case the wind was the motive power.
Both kites and gulls fly with downwardly directed eyes. Their life is one
long search for food. So keen is their vision that no object seems minute
enough to escape their notice. The smallest piece of bread thrown from a
moving ship is immediately pounced upon by the “wild sea-birds that
follow through the air,” but no notice appears to be taken of a piece of
paper rolled up into a ball.
Gulls, like kites, are omnivorous. Some species occasionally prey upon
fish which they catch alive; this method of obtaining food is, however,
the exception rather than the rule among gulls. They are sea-birds merely
in the sense that they usually pick their food off water. They are found
only where there is refuse to be picked up. In those parts of the ocean
that are not frequented by ships gulls are conspicuous by their absence.
They do not, as a rule, travel very far from land; when they do venture
out to sea, it is invariably in the wake of some great ship. Every ocean
liner sheds edible objects all along its course, and so attracts numbers
of gulls. These follow the ship for perhaps two hundred miles, and then
forsake it to return with some homeward-bound vessel.
The seashore and the estuaries of tidal rivers are the favourite
hunting-grounds of the sea-gulls, the flotsam of the rivers and the
jetsam of the waves being the attractions. Numbers of the graceful birds
await the return of the fishing smacks, in order to secure the fish
thrown away by the fishermen. The marine kites are not always content to
wait for rejected fish; not infrequently they boldly help themselves to
some of the shining contents of the nets, and sometimes actually tear the
meshes with their strong sharp bills. In India there is always much
fighting between the gulls and the crows over the fish cast away by the
fishers. The antagonists are well matched. Similar contests have been
recorded in the British Isles. I cull from _The Evening Telegraph_ the
following description of a fight between gulls and rooks over ground
covered with worms which had been killed by a salt-water flood:
“Thousands of gulls and rooks fought each other with a determination and
venom that could not be appreciated unless witnessed. Feathers flew in
all directions; the cawing and screaming were almost deafening. It was a
genuine fight. At first it took place in mid-air, but soon the combatants
came to the ground, and then the struggle centred in and around a fairly
large hillock. Just as the gulls appeared to be gaining the upper hand,
the report of a gun broke up the fight.”
The diet of the kites of the sea is not confined to small things. “A son
of the marshes” states that he has seen them feeding with hooded crows on
the carcases of moorland sheep. In the British Isles gulls frequently
follow the plough and greedily seize the worms and grubs turned up in the
furrow. In London and Dublin, and probably in other places, gulls have
taken up their residence in the parks, where they feed largely on the
bread thrown to the ornamental water-fowl, seizing it in the air before
it reaches the ducks. So tame do these gulls become that they will almost
take bread from the hands of children. Many people labour under the
delusion that these gulls are domesticated ones kept by the authorities
along with the ducks and swans.
Of late years a large colony of gulls has established itself on the
Thames opposite the Temple. These now form one of the sights of London.
The townsfolk take so much interest in the graceful birds that some
individuals earn a living by selling on the Embankment small baskets of
little fish which passers-by purchase in order to throw to the screaming
gulls that hover around expectantly.
Even as hunger frequently drives kites to commit larceny in the farmyard,
so does it sometimes turn sea-gulls into birds of prey.
Mr. W. J. Williams gives an account, in _The Irish Naturalist_, of a
lesser black-headed gull that used to frequent the lake in St. Stephen’s
Green Park. It was wont to rest on the cornice of a house overlooking the
park, till an opportunity presented itself of swooping down and snatching
a duckling. It became so expert at this form of poaching that the Board
of Works had the marauder executed. Another gull which attacked a
duckling was in turn attacked by the parents (a pair of Chilian wigeons),
with such success that the exhausted gull was killed with a stick by one
of the Park constables.
In India gulls do not, I think, venture far inland. The terns regard the
inland waters of Hindustan as their preserve. Some people eat gulls. The
late Lord Lilford declared that the black-headed species is a good bird
for the table. I am not prepared to deny this assertion. I shall not put
it to the test, for, in my opinion, gulls should be a feast only for the
eyes.
XX
RIVER TERNS
A sojourn of a few years in Upper India usually teaches a European to
make the most of the cold weather as it gives place to the heat of
summer. There is a period of a week or two in March and early April when,
although the days are very hot, the nights and early mornings are cool,
when the mercury in the thermometer fluctuates between 104° and 68° F. If
at this season a man is energetic enough to rise at 5.15, shortly after
the birds awake, there are few more pleasant ways of spending the ensuing
three hours than by taking what the French would term a promenade upon
the water. The gliding motion of a boat propelled by sail or oar is
always soothing, and is doubly so when one knows that the breeze which
then blows cool upon the cheek will scorch the face seven hours hence.
The morning excursion on the water is rendered especially enjoyable if it
happens to take place at one of the comparatively few parts of the Ganges
or the Jumna where the river-bed is narrow, so that the water fills the
space between the banks, instead of being, as is more usually the case, a
mere trickle of water meandering through a great expanse of sand. Under
the former conditions it is good to sit in the stern of a gliding boat
and watch the birds that frequent the river.
At sunrise the crow-pheasants (_Centropus rufipennis_) come to the
water’s edge to drink, so that numbers of the long-tailed, black birds
with chestnut wings are to be seen from the boat. Having slaked their
thirst, they hop up the steep bank with considerable dexterity, to
disappear into the stunted bushes that grow on the top of the bank. Then
there are, of course, the regular _habitués_ of the water’s edge—the
birds that frequent it at all hours of the day—the ubiquitous paddy bird
(_Ardeola grayii_), which spends the greater part of its life ankle-deep
in water, waiting motionless for the coming of its prey; the common
sandpiper (_Totanus hypoleucus_), that solitary bird, as small as a
starling, which, on the approach of a human being, emits a plaintive cry
and flies away, displaying pointed wings along the length of which runs a
narrow white bar; the handsome spur-winged plover (_Hoplopterus
ventralis_), whose call is very like that of the did-he-do-it—but we must
not dwell on these littoral birds, for to-day I would write of terns, the
river birds _par excellence_. None of God’s creatures are more attractive
than terns to those who love beauty. That few, if any, of our English
poets have sung the praises of these beautiful birds surely demonstrates
how little attention poets pay to nature, and how artificial are their
writings. This will, I fear, annoy the friends of the poets. I am sorry,
but I cannot help it. It is the fault of the bards for having so grossly
neglected the terns.
In colouring, these superb birds show what endless possibilities are open
to the artist who confines himself to black and white and their
combinations.
There is in the flight of terns a poetry of motion over which no one with
an eye for the beautiful can fail to wax enthusiastic. The popular name
for terns—sea-swallows—is a tribute to their wing power. They are all
designed upon a common plan. Length and slimness characterise every part
of their anatomy, save the legs, which are very short. Terns rarely walk;
nearly all their movements are aerial.
The terns that commonly frequent the rivers of Upper India are of three
species—the black-bellied tern (_Sterna melanogaster_), the Indian river
tern (_S. seena_) with its deeply forked tail, and the whiskered tern
(_Hydrochelidon hybrida_), a study in pale grey. These, when not resting
on a sandbank, are dashing through the air without effort, ever and anon
dropping on to the water to pick something from off the surface, or
plunging in after a fish. Allied to the terns, and found along with them,
are the Indian skimmers (_Rynchope albicollis_), easily recognised by
their larger size and black wings.
The passing of a black crow causes some of the terns to desist from their
piscatorial occupation, in order to mob the intruder. This means that
there are terns’ eggs or young ones in the vicinity. Many species of
birds betray the presence of their nests by displaying unusual pugnacity
at the breeding season. To discover the eggs or young of the terns is not
a difficult matter. It is only necessary to land upon the nearest island
between which and the river bank there is a sufficient depth of water to
prevent jackals fording it. If the island contain eggs or young ones, the
parent birds will make a hostile demonstration by collecting overhead and
flying backwards and forwards, uttering their harsh cries, and the nearer
one approaches the nest the more clamorous do they become. In this manner
they unwittingly inform the nest-seeker whether he is getting “hot” or
“cold,” to use the expressions employed in a nursery game.
The terns which breed on islets in Indian rivers do not appear to do much
incubating in the daytime. There is no need for them to do so, because
the sand grows very warm under the rays of the sun. Moreover, the only
foes to be feared are the crows and the kites, which the terns can keep
at bay more effectually when on the wing than while sitting on the eggs.
Very different is the behaviour of the sea terns, whose eggs are liable
to attack by gulls and crabs. For safety’s sake the sea terns lay in
large colonies, and, to use Colonel Butler’s expression, sit on their
eggs “packed together as close as possible without, perhaps, actually
touching one another.” He once came upon the nests of a colony of
large-crested terns (_Sterna bergii_). The sitting birds did not leave
their eggs until he was within a few yards of them. Having put them up,
he retired to a little distance. “No sooner had I done so,” he writes,
“than both species [i.e. the gulls and terns] began to descend in dozens
to the spot where the eggs were lying. In a moment a general fight
commenced, and it was at once evident that the eggs belonged to _Sterna
bergii_, and that the gulls were carrying them off and swallowing their
contents as fast as they could devour them.” River terns do not construct
any nest. They deposit their eggs on the bare, dry sand. The eggs have a
stone-coloured ground, sometimes suffused with pink, blotched with dark
patches, those at the surface of the shell having a sepia hue, and those
deeper down appearing dark greyish mauve. The eggs, although not
conspicuous, may, without difficulty, be detected when lying on the sand.
Their colouring would seem to be adapted to match a stony, rather than a
sandy environment, but the fact that the colouring of the eggs is but
imperfectly protective does not much matter when the latter lie on a sand
island, to which but few predaceous creatures have access; the
watchfulness of the parent birds more than compensates for the
comparative conspicuousness of the eggs.
Young terns, like most other birds, are born helpless, and are then
covered with a greyish down; but before the tail feathers have broken
through their sheaths, and while the wing feathers are quite rudimentary,
the ternlets learn to run about and swim upon the water. At this stage
the little terns look like ducklings when on the water, and, as they run
along the water’s edge, may easily be mistaken, at a little distance, for
sandpipers.
When a young tern is surprised by some enemy, his natural instinct is to
crouch down, half buried in the sand, and to remain there quite
motionless until the danger has passed. The colouring of his down is such
as to cause him to assimilate more closely to the sandy environment than
the eggs do. If one picks up such a crouching ternlet, the bird will
probably not struggle at all; it may, perhaps, peck at one’s fingers, but
in nine cases out of ten will remain limp and motionless in the hand,
looking as though it were dead, and if it be set upon the ground it falls
all of a heap, and remains motionless in the position it assumed when
dropped. If you take a young tern in your hand and lay it upon its back
on the sand it makes no attempt to right itself, but remains motionless
in that attitude, looking for all the world like a trussed chicken; but
if you turn your back upon it, it will take to its little legs and run,
with considerable speed, to the water, to which it takes just as a duck
does, its feet being webbed at all stages of its existence.
XXI
GREEN BULBULS
Since green is a splendid protective colour for an arboreal creature, it
is surprising that there are not more green animals in existence. The
truth of the matter is that green seems to be a difficult colour to
acquire. There does not exist a really green mammal; while green birds
are relatively few and far between. In India we have, it is true, the
green parrots, the barbets, the green pigeons, the green bulbuls, and the
bee-eaters. Take away these and you can count the remaining green birds
on the fingers of your hands. Curiously enough, the bee-eaters spend very
little time in trees; consequently the beautiful leaf-green livery seems
rather wasted on them. And of the other green birds we may almost say
that they are precisely those that seem least in need of this form of
protection. The parrakeets and barbets, thanks to their powerful beaks,
are well adapted to fighting, while more pugnacious birds than bulbuls
and pigeons do not exist. I think, therefore, that the green liveries of
these birds are not the result of their necessity for protection from
raptorial foes. This livery is a luxury rather than a necessity.
Anatomically speaking, green bulbuls are not bulbuls at all. Jerdon
called them bulbuls because of their bulbul-like habits, although, as
“Eha” points out, they take more after the orioles. Oates tells us that
these beautiful birds are glorified babblers, rich relations of the
disreputable-looking seven sisters. He gives them the name _Chloropsis_.
Seven species of green bulbul are found in India; they thus furnish an
excellent example of a bird dividing up into a number of local races.
When the various portions of a species become separated from one another
this phenomenon often occurs. The common grey parrot of Africa is,
according to Sir Harry Johnston, even now splitting up into a number of
local races. That interesting bird is presenting us with an example of
evolution while you wait. It is quite likely that the process may
continue until several distinct species are formed. We must bear in mind
that there is no essential difference between a species and a race. When
the differences between two birds are slight we speak of the latter as
forming two races; when the divergence becomes more marked we call them
species. Very often systematists are divided as to whether two allied
forms are separate species or mere races. In such cases some peacemakers
split the difference and call them sub-species.
Green bulbuls are essentially arboreal birds. In the olden time when
India was densely wooded I believe that there was but one species of
_Chloropsis_, even as there is but one species of house-crow in India
proper. Then, as the land began to be denuded of forest in parts, these
green bulbuls became a number of isolated communities, with the result
that they eventually evolved into several species. In this connection I
may mention that the grey on the neck of _Corvus splendens_ is much more
marked in birds from the Punjab than in those that worry the inhabitants
of Madras.
Of the green bulbuls only two species occur in South India—the Malabar
_Chloropsis_ (_C. malabarica_) and Jerdon’s _Chloropsis_ (_C. Jerdoni_).
The former, as its name tells us, is found in Malabar. The green bulbul
of the other parts of South India is Jerdon’s form. This handsome bird
does not occur in or about the City of Madras; at least I have never seen
it in the neighbourhood, nor indeed nearer than Yercaud. However, not
improbably it occurs between the Shevaroys and the east coast. If anyone
who reads these lines has seen this bird in that area, I hope that he or
she will be kind enough to let me know. Here let me say that to identify
a green bulbul is as easy as falling out of a tree. He is of the same
size as the common bulbul. His prevailing hue is a rich bright
grass-green—the green of grass at its best. His chin and throat are
black, and he has a hyacinth-blue moustache, so that he deserves his
Telugu name—the “Ornament of the Forest.” His wife is pale green where he
is black and her moustache is of a paler blue. The Malabar species is
easily distinguished by its bright orange forehead. Green bulbuls go
about, sometimes in small flocks, more frequently in pairs. They rarely,
if ever, descend to the ground, but flit about amid the foliage, to which
they assimilate so closely, seeking for the insects, fruit, and seed on
which they feed. Like many other gaily attired birds, they give the lie
to the oft-repeated assertion that it is only the dull-hued birds that
are good songsters. Green bulbuls are veritable gramophones, “flagrant
plagiarists” Mr. W. H. Hudson would call them. Not only have they a
number of pretty notes of their own, but the feathered creature whose
song they cannot imitate remains yet to be discovered. Green bulbuls
might be called Indian mocking-birds were there not so many other birds
in the country that imitate the calls of their fellows. Some
ornithologist with a good ear for music should draw up a list of all our
Indian birds that mock the calls of others, setting against each the
names of these whose sounds they imitate.
Green bulbuls are hardy birds and thrive well in captivity. I saw
recently a specimen in splendid condition at a bird show in London.
“There is one drawback, however,” writes Finn in his _Garden and Aviary
Birds of India_, “to this lovely bird (from a fancier’s point of view),
and that is its very savage temper in some cases. In the wild state Mr.
E. C. Stuart Baker has seen two of these birds fight to death, and
another couple defy law and order by hustling a king-crow, of all birds.
And in confinement it is difficult to get two to live together; while
some specimens are perfectly impossible companions for other small birds,
savagely driving them about and not allowing them to feed. Many
individuals, however, are quite peaceable with other birds, and a true
pair will live together in harmony.”
There is nothing remarkable in the nest of the _Chloropsis_; it is a
shallow cup, devoid of lining, placed fairly high up in a tree. July and
August are the months in which to look for nests. Two eggs usually form
the complete clutch. It would thus seem that green bulbuls have not a
great many enemies to fear. Nevertheless they fuss as much over their
eggs as some elderly ladies of my acquaintance do over their baggage when
travelling. Birds and people who worry themselves unduly over their
belongings seem to lose these more often than do those folk who behave
more philosophically. Take the case of the common bulbuls. These
certainly lose more broods than they succeed in rearing, yet the ado they
make when a harmless creature approaches their nest puts one forcibly in
mind of the behaviour of the captain of a Russian gunboat when an
innocent vessel happens to enter the zone of sea in the centre of which
the Czar’s yacht floats.
XXII
CORMORANTS
Cormorants, like Englishmen, have spread themselves all over the earth.
Save for a few out-of-the-way islands, there is no country in the world
that cannot boast of at least one species of cormorant. Cormorants, then,
are an exceedingly successful and flourishing family. It must be very
annoying for those worthy professors and museum naturalists who are
always lecturing to us about the all-importance of protective colouration
that the most flourishing families of birds—the crows and the
cormorants—are as conspicuous as it is possible for a thing in feathers
to be.
Mr. Seton Thompson well says that every animal has some strong point, or
it could not exist; and some weak point, or the other animals could not
exist. Cormorants have several strong points, and that is why they
flourish like the green bay tree, notwithstanding their conspicuous
plumage. They are as hardy as the Scotchman, as voracious as the ostrich,
as tenacious of life as a cat, to say nothing of being piscatorial
experts, powerful fliers, and champion divers.
The cormorant family furnishes a very good example of the manner in which
new species arise quite independently of natural selection.
Notwithstanding their world-wide distribution, all cormorants belong to
one genus, which is divided up into thirty-seven species. Of these no
fewer than fifteen occur in New Zealand—a country not characterised by a
large avifauna.
One species—the large cormorant (_Phalacocorax carbo_)—flourishes in
almost every imaginable kind of climate and among all sorts and
conditions of birds and beasts. Yet in New Zealand, in a country where
the conditions of existence vary but little, cormorants have split up
into fifteen species. It is therefore as clear as anything can be in
nature that we must look to some cause other than natural selection for
an explanation of the multiplicity of species of cormorant in New
Zealand. It seems to me that the solution of this puzzle lies in the fact
that the conditions of life are comparatively easy in New Zealand.
Consequently a well-equipped bird like a cormorant is allowed a certain
amount of latitude as to its form and colouring. In places where the
struggle for existence is very severe, where organisms have their work
cut out to maintain themselves, the chances are that every unfavourable
variation will be wiped out by natural selection; but if the struggle is
not particularly severe, or if a species has something in hand, it can
afford to dispense with part of its advantage and still survive. Thus it
is that in New Zealand we see a number of different species of cormorant
living side by side. De Vries likens natural selection to a sieve through
which all organisms are sifted, and through the meshes of which only
those of a certain description are able to pass. Bateson compares it to a
public examination to which every organism must submit itself. Those
animals that fail to get through are killed. The standard of the
examination may vary in various parts of the world.
So much for cormorants in general and the puzzle they present to
evolutionists. Let us now consider for a little while our Indian
cormorants. For once India is at a disadvantage as compared with New
Zealand. There are but three species found in this country—the great, the
lesser, and the little cormorant. The last—_Phalacocorax javanicus_—is
the most commonly seen of them all. It is to be found in the various
backwaters round about Madras, being especially abundant in the vicinity
of Pulicat. At the place where the canal runs into the lake there are a
number of stakes driven into the canal bed; these project above the level
of the water, and on every one of them a little cormorant is to be seen.
Cormorants in such a position always put me in mind of the pillar saints
of ancient times. Although very active in the water, cormorants become
statuesque in their stillness when they leave it.
The lesser cormorant (_Phalacocorax fuscicollis_) breeds in nests in the
trees on the islets which stud the Redhills Tank near Madras, also on the
tank at Vaden Tangal, near Chingleput. The third species of cormorant
found in India is the great cormorant (_Phalacocorax carbo_). This is the
one which is world-wide in its distribution. It is a large bird, being
over 2 ft. 6 in. in length. It is said to be capable of swallowing at one
gulp a fish fourteen inches long. It is less gregarious in its habits
than the other cormorants, but it breeds and roosts in colonies. Captain
H. Terry states that this species’ nests are to be met with on a tank
near Bellary. The great cormorant possesses fourteen tail feathers, while
all other cormorants have to put up with twelve. Why the big fellow
should be the happy possessor of two extra caudal feathers is a puzzle
which no one has attempted to solve.
It is not very easy to distinguish the three species of cormorant from
one another. The great cormorant has a conspicuous white bar on each side
of the head. This and his larger size serve to separate him from the two
smaller forms. It is usually possible to distinguish the other two by the
fact that the little cormorant has more white on the throat than his
somewhat larger cousin. But, when all is said and done, it is not of
great importance to distinguish the various species. All cormorants have
almost exactly the same habits. The nests are all mere platforms of
sticks. They are all expert fishermen, and seem equally at home on fresh
or salt water. They can swim either on or under water and move at a
considerable pace, covering nearly 150 yards in a minute. The young are
said to feed themselves by inserting their heads into the gullet of the
parent and pulling out the half-digested fish. Cormorants are readily
tamed and are employed in China to fish for their masters, a rubber ring
being inserted round the lower part of the neck in order to prevent the
fish from going too far. In bygone days, fishing by means of cormorants
was considered good sport, and the royal household used to have its
Master of the Cormorants.
Cormorants’ eggs are of a very pale green colour, and their nests smell
of bad fish, for the owners care nothing about sanitation. Young
cormorants are not nearly so black as their parents, and do not attain
adult plumage till they are four years old.
XXIII
A MELODIOUS DRONGO
Our friend the king crow (_Dicrurus ater_) is so abundant throughout
India, and possesses to so great a degree the faculty of arresting the
attention, that we are apt to overlook his less numerous relatives. In
Ceylon it is otherwise. _Dicrurus ater_ occurs in that fair isle, but
only in certain parts thereof, and is not so abundant as his cousin, the
white-vented drongo (_Dicrurus leucopygialis_). The former has,
therefore, to play second fiddle in Ceylon, where he is usually known to
Europeans as the black fly-catcher. The white-vented drongo is their king
crow—the bird that lords over the _corvi_.
The drongos constitute a well-defined family. When you know one member
you can scarcely fail to recognise the others. They fall into two great
classes, the fancy and the plain, the dandies and those that dress
quietly. The bhimraj, or larger racket-tailed drongo (_Dissemurus
paradiseus_), is the most perfect example of the fancy or ornamental
class. His head is set off by a crest, but his speciality is the pair of
outer tail feathers, which attain a length of nearly two feet.
Of the less ornamental drongos, the king crow is the best-known example.
This bird is found in all parts of India, and occurs in Ceylon. Almost as
widely distributed, but far less abundant, is the white-bellied drongo.
This species may be met with in all parts of India save the Punjab. In
the Western Province of Ceylon it is replaced by a drongo having less
white in the plumage.
It is a moot question whether this last is to be looked upon as a race or
a distinct species. Legge writes: “No bird in Ceylon is so puzzling as
the present, and there is none to which I have given so much attention
with a view to arriving at a satisfactory determination as to whether
there are two species in the island or only one. I cannot come to any
other conclusion than that there is but one, the opposing types of which
are certainly somewhat distinct from one another, but which grade into
each other in such a manner as to forbid their being rightly considered
as distinct species; and I will leave it to others, who like to take the
matter up for investigation, to prove whether my conclusions are
erroneous or not.” Oates has since constituted the birds which have less
white on the lower parts a distinct species, which he calls the
white-vented drongo (_Dicrurus leucopygialis_). He admits that the amount
of white on this form and on the white-bellied species (_Dicrurus
cærulescens_) is variable, and that a bird is occasionally met with which
might, as regards this character, be assigned indifferently to one or the
other species, but, says he, the colour of the throat and breast will, in
these cases, be a safe guide in identification. The parts in question are
grey in the white-bellied species and dark brown in the white-vented
form. It seems to me that a slight difference in the colouring of the
feathers of the throat is not a very safe foundation on which to
establish a new species. However, this piece of species-splitting need
not worry the Anglo-Indian, for the white-vented form is found only in
Ceylon. All drongos with white underparts that occur in India are
_Dicrurus cærulescens_. This bird is not common in Madras; I observed it
but twice during eighteen months’ residence in that city. It is in shape
exactly like the common king crow, and possesses the characteristic
forked tail, but it is a smaller bird, being nine and a half inches in
length, and therefore shorter by fully three inches than the black
drongo. Its upper plumage is deep indigo; the throat and breast are grey;
all the remainder of the lower plumage is white. Its habits are very much
like those of the king crow, but it is less addicted to the open country,
seeming to prefer well-wooded localities. I have never seen the _Dhouli_,
or white-bellied drongo, perched on anything but a branch of a tree. It
almost always catches its insect prey upon the wing, after the manner of
a fly-catcher. Jerdon, however, states that he once saw it descend to the
ground for an insect.
As a singer it is far superior to the king crow. In addition to the harsh
notes of that species it produces many melodious sounds. Tickell
describes its song as “a wild, mellow whistle pleasingly modulated.” It
was the voice of the bird that first attracted my notice. Some eight
years ago, when camping in the Fyzabad District, I heard a very pleasing
but unknown song. Tracking this to the mango tope whence it issued, I
discovered that the author was a white-bellied king crow. Last winter a
member of this species favoured me with a fine histrionic performance. I
was sitting outside my tent one afternoon, when I heard above me a harsh
note that was not quite like that of the king crow. Looking up, I
observed, perched on a bare branch at the summit of the tree, a
white-bellied drongo. Then, as if for my especial benefit, he began to
imitate the call of the shikra; he followed this up by a very fair
reproduction of some of the cries of a tree-pie. Having accomplished
this, he made, first his bow, then his exit. I was much interested in the
performance, since an allied species, the bhimraj, is not only one of the
best songsters in the East, but a mimic second only to the wonderful
mocking-bird of South America.
The white-bellied drongo is so rare in the peninsula of India that not
one of our ornithologists has given us anything like a full account of
its habits, and no one appears to have discovered the nest in India.
Fortunately, it is very common in Ceylon, so that Legge has been able to
give some interesting details regarding its habits. We must bear in mind
that Legge includes both the white-bellied varieties under one species.
If we divide them into two, the question arises to which do his various
observations apply? The reply is to either or both, for Legge was not
able to detect any differences between them, except that perhaps the
white-vented variety has a more powerful voice. He writes: “It is
occasionally, when there is abundance of food about, a sociable species,
as many as three or four collecting on one tree, and carrying on a
vigorous warfare against the surrounding insect world.” Like the king
crow, it is an early riser and a late rooster. It is a great chaser of
crows, and of any creature that dares to intrude into the tree in which
its nest is placed. Needless to say that it detests owls. Says Legge:
“The white-bellied king crow never fails to collect all the small birds
in the vicinity whenever it discovers one of these nocturnal offenders,
chasing it through the wood until it escapes into some thicket which
baffles the pursuit of its persecutors.” But why does he call owls
“nocturnal offenders”? Wherein lies their offence? So far as I can see,
the only crime that owls commit is in being owls. The creatures they prey
upon have reason for disliking them. But owls do not attack
ornithologists. Why, then, should these gentry call them hard names?
The nesting habits of both the white-bellied and the white-vented drongos
are very similar to those of the common king crow. Legge describes the
nest as a shallow cup, almost invariably built at the horizontal fork of
the branch of a large tree at a considerable height from the ground,
sometimes as much as forty feet. The eggs seem to vary as greatly in
appearance as do those of the common king crow.
Since the white-bellied drongo appears to be quite as pugnacious as its
black cousin, and to have almost identical habits, it is strange that it
should be so uncommon in India. As we have seen, its distribution is
wide, so that it seems able to adapt itself to various kinds of climate.
Nevertheless, it is common nowhere in India. What is the cause that keeps
down its numbers? Naturalists are wont to talk airily about natural
selection causing a species to be numerous or the reverse, but unless
they can show precisely how natural selection acts they explain nothing.
Those who write books on natural history convey the impression that it is
the birds and beasts of prey that keep down the numbers of the smaller
fry. As a matter of fact, predaceous creatures seem to exercise but
little influence on the numbers of their quarry. There are hidden causes
at work of which we know almost nothing. Damp and small parasites are
probably far more powerful checks on multiplication than predaceous
creatures. It would seem that there is something in the constitution of
the white-bellied drongo which enables it to outnumber the king crows
proper in Ceylon, but which prevents it from becoming abundant in the
peninsula of India. What this something is we have yet to discover. We
really know very little of the nature of that mysterious force with which
naturalists love to conjure, and which Darwin named Natural Selection. We
write it with a capital N and a capital S, and then imagine that we have
explained everything.
“Twinkle, twinkle, little star,
Now we all know what you are.”

THE INDIAN PITTA
Some Indian birds are adepts at self-advertisement. To use an expressive
vulgarism, they continually “hit you in the eye”; they obtrude themselves
upon you in season and out of season. Others are so retiring that you may
live among them for years without observing them. To this class, to the
class that hide their light under a bushel, the beautiful Indian pitta
(_Pitta brachyura_) belongs. There is at least one favoured compound in
Madras where a pitta, or possibly a pair of them, spends the cool-weather
season. Pittas proclaim their presence by uttering at dawn their cheery
notes, which have been described as an attempt to whistle, in a
moderately high key, the words “quite clear.” If, on hearing this call,
you are sufficiently energetic to go out of doors, you will probably see
on the ground a bluish bird, about the size of a quail, but before you
have had time to examine it properly it will have taken to its wings and
disappeared into the hedge. Those who are not so fortunate as to have
pittas on the premises may be tolerably certain of seeing a specimen by
visiting the well-wooded plot of land bordered on the west by the canal
and on the south by the Adyar River.
This bird is about seven inches in length. Thus it does not measure much
more than a sparrow, but it is nevertheless considerably larger, for the
tail is very short, being barely one inch and a half in length. The crown
is yellow, tinged with orange, and divided in the middle by a broad black
band running from the beak to the nape of the neck, where it meets a
broader black band that passes below the eye. The eyebrow is white. The
back and shoulders are dull bluish green. The upper tail-coverts are pale
blue. There is also a patch of this colour on the wing. The wings and
tail are black, tipped with blue. During flight the pinions display a
white bar. The chin and throat are white. The breast is of the same
yellow hue as the head. There is a large crimson patch under the tail.
Captain Fayrer’s photograph in _Bombay Ducks_ conveys very well the shape
of the bird, but, of course, does not reproduce the most marked feature
of the pitta—its colouring. Indians in some localities call it the
_naurang_—the nine-colours. The bird may truly be said to be arrayed in a
coat of many colours. Unfortunately, such a garment is apt to lead to
trouble. Even as the coat of many colours brought tribulation upon Joseph
of old, so does the much-coveted, multi-hued plumage of the pitta
frequently bring death to its possessor.
Apart from the colouring, it is impossible to confound the pitta with any
other bird. Its long legs and its apology for a tail recall the
sandpiper, but there is nothing else snippet-like about it. The
classification of the bird has puzzled many a wise head. It has been
variously called the Madras jay, the Bengal quail, the short-tailed pye,
the ant-thrush, the painted thrush, and the ground thrush. But it is not
a jay, neither is it a quail, nor a thrush, nor a tailless pye. It is a
bird made on a special model. It belongs to a peculiar family, to a
branch of the great order of perching birds, which differs from all the
other clans in some important anatomical details. Into these we will not
go, for they belong to morphology, the science which concerns itself
chiefly with the dry bones of zoology, with the lifeless aspect of the
science of life.
The Indian pitta is a bird which likes warmth, but not heat, so that it
refuses to live in the Punjab, where the climate is one of extremes—a
spell of cold, then a headlong rush into a period of intense heat,
followed by an equally sudden return to a low temperature. The pitta
seems to occur in all parts of Eastern, Central, and Southern India,
undergoing local migration to the south in the autumn and back again in
the spring. In places where the climate is never very hot or very cold,
as, for example, Madras and the hills in Ceylon, some individuals seem to
remain throughout the year. I have seen pittas in Madras at all seasons,
and I know of no better testimonial to the excellence of the climate of
that city. Jerdon writes of the pitta: “In the Carnatic it chiefly occurs
in the beginning of the hot weather, when the land-winds first begin to
blow with violence from the west; and the birds in many instances appear
to have been blown, by the strong wind, from the Eastern Ghauts, for,
being birds of feeble flight, they are unable to contend against the
strength of the wind. At this time they take refuge in huts, outhouses,
or any building that will afford them shelter. The first bird of this
kind that I saw had taken refuge in the General Hospital at Madras; and
subsequently, at Nellore, I obtained many alive under the same
circumstances.” Other observers have had similar experiences. Bligh, for
instance, states that in Ceylon pittas are frequently caught in bungalows
on coffee estates on cold and stormy days.
It is strange that so retiring a bird as the pitta should find its way
with such frequency into inhabited houses. Jerdon’s explanation is its
“feeble flight,” but I doubt whether he is correct in calling the pitta a
bird of weak flight; it can travel very fast, for short distances at any
rate. It seems to me that the pitta dislikes cold and wind, and therefore
naturally seeks any shelter that presents itself. Not being a garden
bird, it is unaware that the bungalow, which offers such tempting cover,
is the abode of human beings. Possibly another reason why the pitta so
frequently enters bungalows is to avoid the crows. Dr. Henderson tells me
that he was playing tennis some years ago at a friend’s house in Madras
when he saw a bird being chased by a mob of crows. The fugitive took
refuge in the drawing-room of the house, where Dr. Henderson caught it,
and found that it was an uninjured but very much frightened pitta. Mr. D.
G. Hatchell informs me that he once picked up in his verandah a dead
pitta that had probably been killed by crows. The _corvi_ are out-and-out
Tories. They strongly resent all innovation _qua_ innovation. Any
addition to the local fauna is exceedingly distasteful to them. They
object to the foreigner quite as strongly as do (perhaps I should say
“did”) the Chinese. It is for this reason that they mob every strange
bird that shows its face. Now, they seldom come across either the
creatures of the night or the denizens of the thick undergrowth;
consequently, when such venture forth into the light of day the crows
forthwith attack them.
The pitta feeds chiefly on beetles, termites, ants, and other creeping
things, which it seeks out among fallen leaves, after the manner of the
“seven sisters.” The pitta is quick on its feet, and is able to hop and
run with equal ease. It thrives in captivity. It is an excellent pet,
provided it be not kept with smaller birds. It regards these as so much
fresh meat especially provided for it.
The nest of the pitta is described as a globular structure fully nine
inches in horizontal diameter and six inches high, with a circular
aperture on one side. Twigs, roots, and dried leaves are the building
materials utilised. The eggs are exceedingly beautiful. “The ground
colour,” writes Hume, “is China white, sometimes faintly tinged with
pink, sometimes creamy; and the eggs are speckled and spotted with deep
maroon, dark purple, and brownish purple as primary markings, and pale
inky purple as secondary ones. Occasionally, instead of spots, the
markings take the form of fine hair-like lines.”
XXV
THE INDIAN WHITE-EYE
The Indian white-eye (_Zosterops palpebrosa_) is a bird which should be
familiar to everyone who has visited the Nilgiris. To wander far in a
hillside wood without meeting a flock of these diminutive creatures is
impossible. Sooner or later a number of monosyllabic notes will be heard,
each a faint, plaintive cheep. On going to the tree from which these
notes appear to emanate a rustle will be observed here and there in the
foliage. Closer inspection will reveal a number of tiny birds flitting
about among the leaves. These are white-eyes—the most sociable of birds.
Except when nesting, they invariably go about in companies of not less
than twenty or thirty. Each individual is as restless as a wren, so that
some patience must be exercised by the observer if he wish to obtain a
good view of any member of the flock. But by standing perfectly
motionless for a time under the tree in which the birds are feeding he
who is watching will, ere long, be able to make out that the white-eye is
a tiny creature, not much more than half the size of a sparrow. The upper
parts are yellowish green, the chin, throat, and feathers under the tail
are bright yellow, and the remainder of the lower surface of whitish hue.
The most marked feature of the _Zosterops_ is a conspicuous ring of white
feathers round the eye, which causes the bird to look as though it were
wearing white spectacles. From this circle the species derives its
popular names, the white-eye or spectacle bird. Thanks to the conspicuous
eye-ring, it is impossible to mistake the bird.
All feathered creatures that go about in flocks and haunt thick foliage
emit unceasingly a call note, by means of which the members of the flock
keep in touch with one another. This ceaseless cheeping note is probably
uttered unconsciously. Each individual listens, without knowing that it
is doing so, for the calls of its fellows; so long as it hears these it
is happy. When the main volume of the sound grows faint the individual
white-eye knows that his companions are moving away from him; he
accordingly flies in the direction from which their calls are coming,
giving vent, as he goes, to a louder cheep than usual. Whenever a
white-eye flies from one tree to another it utters this more powerful
call and thereby informs its fellows that it is moving forward. This
louder cry stimulates the others to follow the bird that has taken the
lead. All the time they are thus flitting about the white-eyes are busy
picking tiny insects off the leaves. I have never observed them eating
anything but insects. Legge, however, asserts that their diet is for the
most part frugivorous, in consequence of which the birds are, according
to him, very destructive to gardens, picking off the buds of fruit trees,
as well as attacking the fruit itself. He further declares that he has
known caged individuals in England feed with avidity on dried figs.
Hutton also states that white-eyes feed greedily upon the small black
berries of a species of _Rhamnus_, common in the Himalayas.
Notwithstanding the authorities cited, it is my belief that these little
birds are almost exclusively insectivorous. They perform a useful work in
devouring numbers of obnoxious insects, which they extract from flowers.
In so doing their heads sometimes become powdered with pollen, so that
the white-eyes probably, like bees and moths, render service to plants by
carrying pollen from one flower to another.
The search for food does not occupy the whole day. Except at the nesting
season, the work of birds is light. In the early morning the white-eyes
feed industriously; so that by noon they have satisfied their hunger.
They then flit and hop and fly about purely for pleasure. White-eyes,
like all small birds, literally bubble over with energy. They are as
restless as children. Once when walking through the Lawrence Gardens at
Lahore in the days when they had not yet fallen into the clutches of that
enemy of beautiful scenery, the landscape gardener, I came across a
company of these charming little birds disporting themselves amid some
low bushes near a plantation of loquat trees. First one little bird, then
another, then a third, a fourth, a fifth, etc., dropped to the ground,
only to return at once to the bush whence they came. A whole flock
appeared to be taking part in this pastime. There were two continuous
streams, one of descending and the other of ascending white-eyes. These
might have been little fluffy, golden balls with which some unseen person
was playing.
When the heat of the day is at its zenith, white-eyes, like most birds in
India, enjoy a _siesta_. At this hour little gatherings of them may be
seen, each bird huddled against its neighbours on some bough of a leafy
tree.
At the nesting season the white-eye sings most sweetly. The ordinary
cheeping note then becomes glorified into something resembling the lay of
the canary; less powerful, but equally pleasing to the ear.
The nest of the white-eye is a neat little cup, or, as Mr. A. Anderson
describes it, a hollow hemisphere. It is a miniature of the oriole’s
nursery. It is large for the size of the bird, being usually over two
inches in diameter. Some nests are fully two inches deep, while others
are quite shallow. It is composed of fine fibres (i.e. grass stems,
slender roots, moss, and seed down) and cotton, bound together by cobweb,
which is the cement most commonly used by bird masons. The nursery is
invariably provided with a lining. In one nest that I found, this lining
consisted of human hair. Other lining materials are silky down, hair-like
moss and fern-roots, and grass fibres so fine that the horsehairs which
are sometimes utilised look quite coarse beside them. The most wonderful
thing about the nest of this pretty little bird is the manner in which it
is attached to its supports. I have called it a miniature of the oriole’s
nursery, because it is usually suspended from two or more branches by
cotton fibres. I once came upon a nest which was attached to but one
slender branch, and to the tip of this. The end was worked into the
structure of the nest so that the whole looked like a ladle with a very
thin handle. It seemed incredible that so slight a branch could support
the nest and its contents.
I have not been fortunate enough to watch the white-eye building its
nest. Mr. A. Anderson states that the pair—for both the cock and the hen
take part in nest construction—“set to work with cobwebs, and having
first tied together two or three leafy twigs to which they intend to
attach their nest, they then use the fine fibre of the _sunn_
(_Crotalaria juncea_), with which material they complete the outer fabric
of their very beautiful and compact nest. As the work progresses, more
cobwebs and fibre of a silky kind are applied externally, and at times
the nest, when tossed about by the wind (sometimes at a considerable
elevation), would be mistaken by a casual observer for an accidental
collection of cobwebs. The inside of the nest is well felted with the
down of the _madar_ plant, and then it is finally lined with fine hair
and grass stems of the softest kind.” The nest is usually situated within
three or four feet of the ground, but is sometimes placed at much higher
elevations.
In South India, the time to look for white-eyes’ nests is from January to
March. In the north, the majority of nests are found between April and
June.
The eggs are a beautiful pale blue. Most commonly only two seem to be
laid. There are, however, many cases on record of three and a few of four
eggs. This is an unusually small clutch. Nevertheless it is unlikely that
a pair of white-eyes bring up more than two broods in the year. These
facts, when taken in conjunction with the wide distribution of the
species, indicate that the white-eye meets with exceptional success in
rearing its young. The nest is usually well concealed in the depths of a
leafy bush. Squirrels and lizards must find the suspended nursery
difficult of access. In addition to this we must bear in mind that
white-eyes are plucky little creatures. Mr. Ball describes how he saw one
of them attacking a rose-finch, a vastly more powerful bird, and drive it
away from the flowers of the _mohwa_, which form a favourite
hunting-ground of the white-eye.
As I have repeatedly stated, pugnacity is a more valuable asset than
protective colouration in the struggle for existence.
Lastly, the white-eye appears able to thrive under greatly varying
conditions of climate.
These advantages possessed by white-eyes, I think, explain why the clutch
of eggs is so small.
White-eyes make excellent pets. They will live amicably along with
amadavats in a cage. Finn is my authority for saying that soft fruit,
bread and milk, and small insects are all the food required by
white-eyes, and they are so easy to keep that many specimens are sent to
Europe.
XXVI
GOOSEY, GOOSEY GANDER
The goose, like certain ladies who let lodgings, has seen better times.
It is a bird that has come down in the world. For some reason which I
have never been able to discover, it is nowadays the object of popular
ridicule. It is commonly set forth as the emblem of foolishness.
Invidious comparisons are proverbially drawn between it and its more
handsome cousin, the swan. The modern bards vie with one another in
blackening its character. As Phil Robinson says, “It does not matter who
the poet is—he may be anyone between a Herbert and a Butler—the goose is
a garrulous fool, _et præterea nihil_.” Well may the bird cry _O tempora!
O mores!_ It has indeed fallen upon evil days. Things were not ever thus.
Time was when men held the goose in high esteem. Livy was loud in his
praises of the bird. Pliny was an ardent admirer thereof. The Romans used
to hold a festival in honour of the feathered saviour of the Capitol. The
degradation of the goose is, I fear, a matter of looks. Its best friend
can scarcely call it handsome. It is built for natation rather than
perambulation; nevertheless it spends much time out of water and feeds
chiefly on _terra firma_. It is probably a bird that is undergoing
evolution, a bird that is changing its habits. It has taken to a more or
less terrestrial existence, but has not yet lost what I may perhaps call
the aquatic waddle. While walking it looks as though it might lose its
balance at any moment. As a matter of fact, the goose is no mean
pedestrian, and is capable of performing considerable journeys on foot.
When pressed, it can show a fine turn of speed. This I have had some
opportunity of observing in the Zoological Gardens at Lahore. A crane
(_Grus antigone_) is confined in the water-birds’ enclosure along with
the ducks, geese, pelicans, etc. Now, cranes are the most frolicsome and
playful of birds. In no other fowl is the sense of humour more highly
developed. The crane in question continually indulges in “cake walks,”
and cuts other mad capers. Sometimes it is seized with the impulse to
“clear the decks,” that is to say, the banks of the ornamental pond. The
operation is conducted as follows: The crane opens out its wings, takes
two wild jumps into the air, then rushes at the nearest duck or goose,
with wings expanded, looking as though it were going through one of the
figures of the serpentine dance. The frightened duck flees before the
crane; the latter keeps up the chase until the duck takes refuge in the
water. Having succeeded in its object, the crane trumpets loudly and
performs a dance which a Red Indian on the war-path could scarcely hope
to emulate. It next turns its attention to some other inoffensive duck or
goose. It is while being thus chased that pinioned geese show a fine turn
of speed. Fly they cannot, so they sprint with expanded wings.
The goose is a great favourite of mine. The more one sees of the bird the
more one likes it and appreciates its good qualities. It is a creature of
character. It rapidly forms attachments, and will sometimes follow about,
like a dog, the person to whom it has taken a fancy. A curious instance
of this was recorded many years ago by _The Yorkshire Gazette_. A gander
belonging to a farmer developed a liking for an old gentleman. The bird
used to go every morning from the farmyard to the house of the said
elderly gentleman and awake him by its cries. It would then accompany him
the whole day in his walks and strut behind him in the most frequented
streets, unmindful of the screams of the urchins by whom the strange pair
were often followed. When the old gentleman sat down to rest the gander
used to squat at his feet. When they were approaching a seat on which the
old man was accustomed to sit the gander used to run on ahead and signify
by cackling and flapping of wings that the resting-place was reached.
When anyone annoyed the old gentleman the gander would express its
displeasure by its cries and sometimes by biting. When its friend went
into an inn to take a glass of ale, the bird used to follow him inside if
permitted; if not allowed to do so, it would wait outside for him.
One should not of course accept as gospel truth everything one reads in a
newspaper. It is necessary to discriminate. Thus, when a well-known
weekly journal produces a picture of the ladies of a Sultan’s harem
dancing unveiled before a distinguished company of gentlemen, one begins
to wonder whether truth really is stranger than fiction. However, I see
no reason to doubt the substantial accuracy of the story of the Yorkshire
gander. The goose is an exceptionally intelligent bird and is very easily
tamed. I once made friends with a goose in the Zoological Gardens at
Lahore. It was a white, bazaar-bred bird. Whenever it saw me it used to
walk up to the fence and emit a low note of welcome. I was able to
distinguish that particular bird from the other geese by the fact that a
piece had been broken off its upper mandible.
I am glad to notice that Mr. W. H. Hudson, one of the leading British
ornithologists, has a high opinion of the goose. In his _Birds and Man_
he gives a delightful account of the home-coming of a flock of tame geese
led by a gander. He writes: “Arrived at the wooden gate of the garden in
front of the cottage, the leading bird drew up square before it, and with
repeated loud screams demanded admittance. Pretty soon in response to the
summons, a man came out of the cottage, walked briskly down the
garden-path and opened the gate, but only wide enough to put his right
leg through; then placing his foot and knee against the leading bird he
thrust him roughly back; as he did so three young geese pressed forward
and were allowed to pass in; then the gate was slammed in the face of the
gander and the rest of his followers, and the man went back to the
cottage. The gander’s indignation was fine to see, though he had probably
experienced the same rude treatment on many previous occasions. Drawing
up before the gate again, he called more loudly than before; then
deliberately lifted a leg, and placing his broad webbed foot like an open
hand against the gate, actually tried to push it open. His strength was
not sufficient, but he continued to push and call until the man returned
to open the gate and let the birds go in.”
If only for his sturdy independence and his insistence on his rights the
gander is a bird whose character is worthy of study. He is courageous
too; so is his wife. She will stand up fearlessly to a boy, a kite, or
even a fox, when her brood is threatened. Last year in the Lahore
Zoological Gardens a goose hatched a number of goslings. The kites
regarded these as fair game, and, in spite of the efforts of the mother,
carried off several of the young birds. Thereupon four ganders took
counsel and constituted themselves a bodyguard for the goose and chicks,
one or more of them being always on duty. In spite of this a kite managed
to secure another gosling. The mother and her remaining five chicks were
then placed in a cage; notwithstanding this, the ganders still maintained
their guard and cried loudly whenever a human being approached the cage
containing the brood.
The goose, like the swan, uses its wing as a weapon. When it attacks it
stretches its neck and head low along the ground and hisses; it then
dashes at its adversary, seizes him with beak and claws, and lays on to
him right well with its powerful wings.
Here endeth the account of “Goosey, Goosey Gander.” I must apologise to
the geese in their natural state for having completely ignored them. We
will make amends by indulging in a wild-goose chase at an early date!
XXVII
GEESE IN INDIA
Seven or eight species of goose have been recorded as winter visitors to
India. With two exceptions they honour us with their presence only on
rare occasions, and do not really form part and parcel of our Indian
avifauna. The exceptions are the grey lag goose and the barred-headed
goose, which visit India every winter in their millions. It is these that
form the subject of this essay. It is difficult for the dweller in the
south to realise how abundant geese are in Northern India throughout the
cold weather. Flocks of them fly overhead so frequently that they
scarcely attract notice. Each flight looks like a great trembling,
quivering V, floating in the air, a V of which the angle is wide and one
limb frequently longer than the other. During flight geese are
distinguishable from cranes and storks by this V-shaped formation, and by
the fact that they never sail on expanded wings; they progress by means
of a steady, regular motion of the pinions, and are able to cover long
distances in short time. Geese on the wing are distinguishable from the
smaller species of duck by their larger size, and from Brahminy ducks
(_Casarca_ _rutila_) by their lighter colour. Moreover, the curious note
of this last species is very different from the cackle of geese. Brahminy
ducks go about in couples; geese fly in flocks.
Like most birds which breed in the far north, geese are largely
nocturnal; their cries as they fly overhead are among the commonest of
the sounds which break the stillness of the winter night in Upper India.
They feed mainly in the hours of darkness, and do a certain amount of
damage to the young wheat; nor do they leave their feeding ground until
the sun is high in the heavens, when they repair to a river bank or
shallow lake, where they love to bask in the sun, all with the head
tucked under the wing, save one or two who do duty as sentinels.
The grey lag goose of India is, I believe, identical with the wild goose
of England. This is a belief not shared by everyone. For over a century
this species has been the plaything of the systematist. Linnæus classed
ducks and geese as one genus—_Anas_. This goose he called _Anas anser_,
the goose-duck. But it was soon recognised that ducks and geese are not
sufficiently nearly related to form a common genus; hence, the geese were
formed into the genus _Anser_, and the grey lag goose was then called
_Anser cinereus_, the ashy-coloured goose, a not inappropriate name,
although the bird is brown rather than grey. But the name was not allowed
to stand. For some reason or other it was changed to _Anser ferus_. Then
it was altered to _Anser anser_—the goosey goose, presumably meaning the
goose _par excellence_. Then Salvadori discovered, or thought that he
discovered, that the grey lag geese of the East are not quite like those
of the West; he therefore made two species of the bird, calling the
Indian variety _Anser rubirostris_, the red-billed goose. Alphéraky
denies the alleged difference. The result is that the bird has some
half-dozen names, each of which has its votaries. It is this kind of
thing which deprives classical nomenclature of all its utility. Until
ornithologists learn to grasp the simple fact that the external
appearance of every living creature is the result of two sets of forces,
internal or hereditary, and external or the influence of environment,
they will always be in difficulty over species. Englishmen who dwell in
sunny climates get browned by the sun, yet no one dreams of making a
separate species of sun-burned Englishmen. Why, then, do so in the case
of birds whose external appearance is slightly altered by their
environment?
Even as scientific men have toyed with the Latin name of the bird, so
have compositors played with its English name. Nine out of ten of them
flatly decline to call it the grey lag goose; they persist in setting it
down as the grey _leg_ goose. If the bird’s legs were grey this would not
matter. Unfortunately they are not. In extenuation of the conduct of the
compositor there is the fact that etymologists are unable to agree as to
the meaning and derivation of the word lag.
The other common species of goose is the barred-headed goose (_Anser
indicus_). This is not found in Europe. It is a grey bird, more so than
the grey lag goose, with two black bands across the back of the head. The
upper one runs from eye to eye, the lower is parallel to, but shorter
than, the upper bar. The back of the neck is black and the sides white.
There is some black in the wings. The bill and feet are yellow. Both
these species of goose are a little smaller than the domestic bird.
Geese are very wary creatures, and possess plenty of intelligence. They
all seem to know intuitively the range of a gun, and as they object to
being peppered with No. 2, or any other kind of shot, it is necessary for
the sportsman to have recourse to guile if he would make a bag. It is
this which makes shooting them such good sport. Every bird obtained has
to be worked for. By rising very early in the morning the gunner may
sometimes get a shot at them while they are feeding. They seem to be less
wary then than later in the day. Sometimes, when riding at sunrise, I
have suddenly found myself within forty yards of a flock of geese feeding
in a field.
They usually indulge in their midday siesta in an open place, and
invariably post sentinels. For this reason they do not give one much
opportunity of observing them. They cannot, or pretend they cannot,
distinguish between the naturalist and the sportsman. In this, perhaps,
they are wise. Their intelligence has, I think, been exaggerated. Last
winter, when punting down the Jumna, I noticed a flock of geese resting
on the moist sand at the water’s edge. Behind them was a semi-circular
sandbank, some fifteen feet in height. This bank sheltered the geese from
the wind. Birds, like ladies, object to having their feathers ruffled. It
occurred to me that owing to the sandbank one could approach quite near
to the flock unobserved. Knowing that geese are creatures of habit, I
counted on the flock being at the identical spot next day. Consequently,
I returned the following morning and approached on all fours from the
sandbank side, and was rewarded by securing a barred-headed goose. I
repeated the operation on the following day, and again bagged a goose.
The third day I was unable to visit the place, so sent a friend, who was
only prevented from slaying a goose by the fact that two Brahminy ducks
in mid-stream saw him approaching and gave the alarm. We left the camp
the next day. I do not, therefore, know whether the geese continued to
frequent that danger-fraught sandbank. The fact that they allowed
themselves to be caught napping thrice shows that they have not quite so
much intelligence as some people credit them with. For all that, the
goose is no fool.
XXVIII
A SWADESHI BIRD
I commend the common peafowl (_Pavo cristatus_) to the Indian patriot,
for it is a true _Swadeshi_ bird. It is made in India and nowhere else.
The beastly foreigner does, indeed, produce a cheap imitation in the
shape of _Pavo muticus_—the Javan peafowl; but with this the patriotic
Indian bird will have nothing to do. The two species are very like in
appearance, the most noticeable difference being in the shape of the
crest; that of the Indian species is like an expanded fan, while the
cranial ornament of the Javan species resembles a closed fan.
Notwithstanding their similarity they do not interbreed when brought
together. This, I am aware, was not Jerdon’s view. He stated that hybrids
between the two species were not rare in aviaries. In this particular
instance Jerdon, _mirabile dictu_, seems to have been wrong; he probably
mistook the japanned variety of the common bird for a hybrid. My
experience tends to show that the two species will not interbreed. Caste
feeling evidently runs high.
Peafowl are distributed all over India; they occur in most localities
suited to their habits, that is to say where there is plenty of cover,
good crops, and abundance of water. They are very plentiful in the
Himalayan _terai_, where they are a source of annoyance to the sportsman.
You are sitting in your _machan_, listening to the approaching line of
beaters. Presently there is a rustle among the fallen leaves; a creature
is making its way through the undergrowth. You listen intently, and
perceive with satisfaction that the moving object is coming towards your
_machan_. You are now all attention, and grasp your rifle in such a
manner that it can, in an instant, be brought to your shoulder. Then, to
your disgust, a peacock emerges with a
good-morning-have-you-used-Pear’s-soap air. When, after about half a
dozen of these false alarms, a bear appears, you are, as likely as not,
unprepared for him.
In many parts of Northern India, notably in those districts through which
the Jumna and Ganges run, peafowl are accounted sacred by the Hindu
population. If you shoot one in such a locality the villagers have a
disagreeable way of turning out _en masse_, armed with _lathis_. The
reverence for the peacock is curiously local. In one village the people
will invite you to shoot the birds on account of the damage they do to
the crops; while the inhabitants of a village at a distance of less than
a hundred miles will send a wire to the Lieutenant-Governor if you so
much as point a gun at the sacred fowl. I once camped in a district where
peafowl were exceptionally numerous, and on this account I concluded that
they were venerated by the populace. But, sacred or not, I hold that
there is nothing to equal a young peafowl as a table bird, so I used to
mark down the trees in which the pea-chicks roosted, and return to the
spot with a gun, after the shades of night had fallen. Having shot a
sleeping bird I smuggled it into camp in order not to offend the village
folk. After having taken these precautions for about two months I learned
that the people entertained no objection whatever to the birds being
shot! Peafowl are objects of veneration in all the Native States of
Rajputana. These are strongholds of orthodox Hinduism. Nilgai, even, may
not be shot, because the Pundits, not being zoological experts, labour
under the delusion that these ungainly antelope are kine.
In some parts of India peafowl may be seen in a state of
semi-domestication and are regularly fed by temple keepers. The drawback
to the peacock as a domestic bird is that he renders the night hideous by
his cries, which resemble those of an exceptionally lusty cat. Blanford,
I notice, called them “sonorous.” There is no accounting for taste. In my
opinion, peafowl should be seen and not heard.
The peacock, like the ostrich, is almost omnivorous; it feeds chiefly
upon grain, buds, and shoots of grass, but it is not averse to insects,
and will devour many of these, which are generally supposed to be
inedible and so warningly coloured. Lizards and snakes complete a varied
menu.
The peafowl is a bird of considerable interest to the zoologist, as it
affords a striking example of sexual dimorphism. In plain English, the
cock differs greatly from the hen in appearance. In some species, such as
the myna, the crow, and the blue jay, the cock is indistinguishable from
the hen. In others, as, for example, the sparrow, the sexes differ
slightly in appearance. In others, again, the cock differs from the hen
as the sun does from the moon. The peafowl is one of these.
Zoologists have for years been trying to find out why in some species the
cock resembles the hen while in others it does not. Humiliating though it
be, we must, if we are honest, admit that we are little, if any, nearer
the explanation of the phenomenon than we were a couple of centuries ago.
Darwin thought that the pretty plumage of the males was due to selection
on the part of the females. He tried to prove that hens are able to pick
and choose their mates, that they have a keen eye for beauty. Just as
political economists of Ricardo’s school teach us that every man marries
the richest woman who will have him, so does Darwin ask us to believe
that hens always mate with the best-looking of their suitors, that they
quiz each with the eye of an art critic, and pronounce judgment somewhat
as follows: “Number one is no class; his train is too short. I would not
be seen dead beside number two; he looks as though he had issued from a
fifth-rate dyer’s shop. I’ll take number three, he is the pick of the
bunch.” Darwin argued that the showy cocks are fully alive to their good
looks, and know how to show them off to best advantage. There is much to
be said in favour of his theory. A peacock, when he sees a hen that he
admires, promptly turns his back upon her, erects his great train and his
paltry little tail which is hidden away underneath. He then spreads out
his feathers and suddenly faces the hen, flapping his wings, and causing
every feather in his body to quiver with a curious noise, so that he
appears to be seized with a shivering fit. The hen either affects not to
notice him, or assumes an air of studied boredom. Unfortunately for
Darwin’s theory, peacocks sometimes show off in the absence of other
living creatures. Moreover, a young cock with a train of which a magpie
would be ashamed will strut about and show off with the greatest pride.
There are in the “Zoo” at Lahore a number of albino peacocks. These,
although handsome birds, are not so beautiful as the coloured variety,
being a uniform white; nevertheless they are exceedingly popular with the
hens, and experience no difficulty in cutting out all the coloured beaux.
It is very naughty of the hens to prefer the albinos, for by so doing
they deal a severe blow to the theory of sexual selection. Stolzman has
quite another hypothesis to account for the superior beauty of the male.
As any “suffragette” will tell you, the male is a more or less
superfluous being; the world would get along much better if he were less
plentiful. Hence, in the interests of the race, it is necessary that the
numbers of the pernicious creature should be strictly limited. Nature
has, therefore, arrayed cock-birds in coats of many colours so that they
shall be easily seen and devoured by beasts of prey! Wallace, again,
thinks that the comparatively sombre hues of the hen are due to her
greater need of protection, as it is she who does all the incubating. An
objection to this view is the well-known fact that many showy cocks sit
on the eggs turn-about with the dull-coloured hens in open and exposed
nests.
Peafowl are polygamous. The breeding season begins in May and continues
all through the hot weather. The typical nest is described as “a broad
depression scratched by the hen, and lined with a few leaves and twigs or
a little grass.” It is usually made amongst thick grass or in dense
bushes, but occasionally there is no attempt at concealment. Mr. A.
Anderson states that peahens frequently lay at high elevations, that he
has on several occasions taken their eggs from the roofs of huts of
deserted villages on which rank vegetation grew to a height of two or
three feet. My experience of captive birds bears out this. The peahens in
the Lahore “Zoo” lay all their eggs on a broad shelf in their aviary,
some fifteen feet above the level of the ground. Seven or eight eggs of a
dirty white hue are laid. These are, in the words of Hume, “delicious
eating.”
XXIX
THE INDIAN REDSTART
Poets, naturalists, essayists, and novelists have with one accord and
from time immemorial extolled the English spring. In this particular
instance their eulogies are justified, for spring in England is like a
wayward maiden: when she does choose to be amiable, she is so amiable
that her past perverseness is at once forgiven. But why do not
Anglo-Indian writers sing to the glories of the Indian autumn? Is it not
worthy of all praise? It is the season which corresponds most nearly to
spring in England, and is as much longed for. Even as spring chases away
the gloomy, cheerless English winter, so does autumn drive away the
Indian hot weather, unpleasant everywhere, and terrible in the plains of
the Punjab and the United Provinces. Those condemned to live in Portland
Gaol probably suffer fewer physical discomforts than they who spend the
summer in any part of the plains of Northern India. First, weeks of a
furnace-like heat, when to breathe seems an effort; then a long spell of
close, steamy heat, so that the earth seems to have become a great
washhouse. From this the Anglo-Indian emerges, limp, listless, and
languid. How great, then, is his joy when one day he notices a suspicion
of coolness in the air. Day by day this coolness grows more appreciable,
so that by late September or early October to take an early-morning
stroll becomes a pleasure. Then the sky is bluer, the atmosphere is
clearer, the foliage is greener than at any other time of the year. Then
at eventide the village smoke hangs low, looking like a thin blue
semi-transparent cloud resting lightly on the earth—a sure sign of the
approaching cold weather. Then, too, the winter birds begin to appear.
Even as the cuckoo is welcomed in England as the harbinger of the sweet
spring, so in Northern India is the redstart looked for as the herald of
the glorious cold weather. Within a week of the first sight of that
sprightly little bird will come the day when punkahs cease to be a
necessity. Last year (1907) the hot weather lingered long, and the
redstarts were late in coming. It was not until the 27th September that I
observed one at Lahore.
Several species of redstart are found within Indian limits, but only one
of them haunts the plains, and so thoroughly deserves the name of the
Indian redstart (_Ruticilla rufiventris_). This species visits India in
hundreds of thousands from September to April.
I have observed it in the city of Madras, but so far south as that it is
not common, being a mere straggler to those parts. In the Punjab and the
United Provinces, however, it is exceedingly numerous. Throughout the
cold weather at least one pair take up their abode in every compound.
The Indian redstart is a sexually dimorphic species, that is to say the
cock differs from the hen in appearance; the former, moreover, is
seasonally dimorphic. The feathers of his head, neck, breast, and back
are black with grey fringes. In the autumn and early winter the grey
edges completely obliterate the black parts, so that the bird looks grey.
But during the winter the grey edges gradually become worn away, and the
black portions then show, so that by the middle of the summer the cock
redstart is a black bird. Thus he remains until transformed by the
autumnal moult. His under parts are deep orange, and his lower back and
all the tail feathers, except the middle pair, are brick-red. Now, when
the tail is unexpanded the two middle caudal feathers are folded over the
others, and hide them from view, and, as the lower back is covered by the
wings, the red parts are not visible when the bird walks about looking
for food; but the moment it takes to its wings all the red feathers
become displayed, so that the bird, as it flies away, looks as though its
plumage were almost entirely red. Hence the name redstart—“start” being
an old English word for tail. Another popular name for the bird is
firetail.
Two species of redstart visit England, and these also are characterised
by reddish tails. The hen Indian redstart is reddish brown where the cock
is grey or black, and red where he is red. The gradual change in colour
undergone by the cock redstart every year is instructive, because it
seems to show that the bird is even now undergoing evolution. I think it
likely that the feathers of the cock were at one time uniformly grey and
that they are becoming a uniform black. The tendency seems to be for the
grey margin to become narrower. It will probably eventually disappear. In
some birds it is so narrow that much black shows even after the autumn
moult; in others the margin is so broad that it never disappears. What is
causing this change in plumage? It cannot be the need for protection. The
incipient blackness is probably an indirect result of either natural or
sexual selection. Thus birds with black bases to their feathers may be
either more robust or have stronger sexual instincts than those which
have scarcely any black. In the former case natural selection, and in the
latter sexual selection, will tend to preserve those individuals which
have the least grey in their feathers. This idea of the connection
between colour and strength is not mere fancy. Cuckoo-coloured
(barred-grey) birds are very common among ordinary fowls, but are, I
believe, never seen among Indian gamecocks. Grey plumage seems to be
inconsistent with fighting propensities. Black, on the other hand, seems
to be a good fighting colour. Most black-plumaged birds, as, for example,
the king crow, the various members of the crow tribe, and the coot, are
exceedingly pugnacious.
Redstarts live largely on the ground, from which they pick their food.
This appears to consist exclusively of tiny insects. They sometimes hawk
their quarry on the wing. They are usually found near a hedge or thicket,
into which they take refuge when disturbed. They show but little fear of
man, and, consequently, frequent gardens. They occasionally perch on the
housetop. Indeed, they are quite robin-like in their habits, and the
species, thanks to its reddish abdomen, looks more like the familiar
English robin than does the Indian robin.
The Indian redstart, like all its family, has a peculiar quivering motion
of its tail, which is especially noticeable immediately after it has
alighted on a perch; hence its Hindustani name, _Thir-thira_, the
trembler. Its Telugu name is said to be _Nuni-budi-gadu_—the oil-bottle
bird—a name of which I am unable to offer any explanation. Eurasian boys
call it the “devil bird,” for reasons best known to themselves.
The redstart stays in India until May, when it goes into Tibet and
Afghanistan to breed. A few individuals are said to spend the summer in
India. There are in the British Museum specimens supposed to have been
shot at Sambhar in July and Ahmednagar in June. I have never observed
this bird in India between the end of May and the beginning of September,
and am inclined to think that the above dates have been incorrectly
recorded.
XXX
THE NIGHT HERON
Some American millionaires are said to sleep for only three hours out of
the twenty-four. I do not believe this; I regard the story as a
fabrication of the halfpenny paper. But, even if it be true, the night
heron (_Nycticorax griseus_) is able to eclipse the performance. That
bird only sleeps when it has nothing better to do. It looks upon sleep as
a luxury, not a necessity. As its name implies, it is a creature of the
night; but it is equally a day bird. You will never catch it napping.
Just before sunset, when the crows, wearied by the iniquities they have
wrought during the day, are wending their way to the corvine dormitory,
the night herons sally forth from the trees (“roosts” would be a misnomer
for them) in which they have spent the day and betake themselves, in twos
and threes, to the water’s edge. As they fly they make the welkin ring
with their cries of _waak, waak_, or _quaal, quaal_—sounds which may be
likened to the quacking of a distressed duck. Having arrived at their
feeding-ground, they separate and proceed to catch fish and frogs in the
manner of the orthodox heron. After an all-night sitting, or rather
standing, in shallow water, they return to their day quarters, where they
are popularly supposed to sleep. They may possibly spend the day in
slumber when they have neither nests to build nor young to feed. I am not
in a position to deny this, never having visited a heronry on such an
occasion. I speak, however, as one having authority when I say that all
through the nesting season the night heron works harder during the hours
of daylight than the British workman does. At the present time (April)
thirty or forty night herons are engaged in nesting operations in the
tall trees that grow on the islands in the ornamental pond that graces
the Lahore Zoological Gardens, and as I visit those gardens almost daily
I have had some opportunity of observing the behaviour of our night bird
during the daytime. I may here say that night herons seem very partial to
Zoological Gardens, inasmuch as they also resort to the Calcutta “Zoo”
for nesting purposes. This is, of course, as it should be. Every
well-conditioned bird should bring up its family in a “zoo” by
preference. Had birds the sense to understand this, many of them would be
spared the miseries of captivity.
Before discoursing upon its nesting habits it is fitting that I should
try to describe the night heron, so that the bird may be recognised when
next seen. I presume that everyone knows what a heron looks like, but
possibly there exist persons who would be at a loss to say wherein it
differs from a stork or a crane. It may be readily distinguished from the
latter by its well-developed hind toe. Storks and herons are perching
waders, while cranes do not trust themselves to trees because they cannot
perch, having no hind toe to grasp with. The heron’s bill is flatter and
more dagger-shaped than that of a stork. Moreover the former possesses,
inside the middle claw, a little comb, which the stork lacks. The heron
flies with neck drawn in, head pressed against the back, and beak
pointing forwards. It never sails in the air, but progresses, like the
flying-fox, with a steady, continuous flapping motion. So much for herons
in general. To those who would learn more of these and other long-legged
fowls I commend Mr. Frank Finn’s excellent little book, entitled _How to
Know the Indian Waders_.
The night heron is considerably smaller than the common heron—the heron
we see in England, and larger than the Indian paddy bird—the ubiquitous
fowl that looks brown when it is standing and white when it is flying.
The head and back of the night heron are black, the remainder of the
upper plumage is grey, the lower parts are white. There are two or three
long, white, narrow feathers, which grow from the back of the head and
hang down like a pigtail. The eye is rich ruby-red. Young night herons
are brown with yellowish spots, and the eye is deep yellow.
Any resident of Madras may see this species if he repair to the Redhills
Tank. One of the islands in that tank supports a considerable population
of night herons and little cormorants. The former nest in the trees on
the island in July. The place is well worth visiting then. As the boat
carrying a human being approaches the islet, all the night herons fly
away without a sound. They love their young, but not so much as they love
themselves, so they leave their offspring at the first approach of the
human visitor and remain away until he turns his back on their
nesting-ground. A night heron never allows his valour to get the better
of his discretion. The nest is a platform of twigs placed anywhere in a
tree. Four pale greenish-blue eggs are laid. A heronry is a filthy place.
The possessors are, like our Indian brethren, utterly regardless of the
principles of sanitation. The whole island will be found white with the
droppings of the birds, and the unsavoury smell that emanates therefrom
would do credit to a village inhabited by _chamars_. Although they are
evil-tempered, cantankerous creatures, night herons always nest in
company. It is no uncommon thing to find half a dozen nests in the same
tree, so that the sitting birds are able to compare notes while engaged
in the duties of incubation. Both the parent birds take part in nest
construction, and, as they work by day, it is quite easy to watch the
process. They wrench small branches from trees, and, as they have only
the beak with which to grasp these, they find twig-gathering hard work.
When a twig has been secured it is dropped on to the particular part of
the tree in which the bird has thought fit to build. Forty or fifty twigs
dropped haphazard in a heap constitute the nest. The birds make a great
noise while engaged in building. Quarrels are of frequent occurrence. It
sometimes happens that two birds want the same twig; this invariably
gives rise to noisy altercation. The crows too are provocative of much
bad language on the part of the night herons. Whenever any of the crows
of the neighbourhood has nothing else to do, he says to a kindred spirit:
“Come, let us worry the night herons.” Whereupon the pair—_Arcades
ambo_—go and pretend to show the herons how to build a nest.
When, my friends, you consider the untidiness and filthiness of the
heron’s nest, you will be able to appreciate to the full the audacity of
the latest falsehood circulated by the plume trade—to wit, the egret
plucks out its nuptial plumes, which constitute the “osprey” of commerce,
and weaves these into the nest to make it more cosy; and, after the young
ones are fledged, some honest fellow visits the nest and disentangles the
plumes therefrom!
A baby heron is a disgustingly ugly creature. It is a living caricature.
Patches of long hair-like feathers are studded, apparently haphazard,
over its otherwise naked body and give it an indescribably grotesque
appearance. It looks like a bird in its dotage. If you lift a young heron
out of the nest you will probably find that his “corporation” is
distended to bursting-point, and, if you do not handle him carefully, a
half-digested frog will, as likely as not, drop out of him!
The farther north one goes the earlier in the year does the night heron
breed. In Kashmir the nesting season is in full swing in March. In the
Punjab April and May are the nesting months; in Madras the birds do not
begin to build until July; and I have seen eggs at the end of August. It
is my belief that the night heron is a migratory bird. During the winter
months not a single specimen of that species is to be seen in or about
Lahore, but they migrate there regularly every April. They disappear
again to I know not where when they have reared up their young.
XXI
THE CEMENT OF BIRD MASONS
Birds may be divided into two classes—those which build nests and those
which do not. To the latter belong the parasitic starlings and cuckoos,
which drop their eggs in the nests of other birds; those, such as
plovers, which lay their eggs on the bare ground; and those which deposit
them in holes, in the earth, in trees, in banks, or in buildings, as, for
example, the Indian roller or blue jay (_Coracias indica_).
Intermediate between the birds that build nests and those which do
not—for there are no sudden transitions, no sharply defined lines of
division in nature—are those birds which merely furnish, more or less
cosily, the ready-made holes in which they deposit their eggs. The common
myna (_Acridotheres tristis_) affords a familiar instance of this class
of birds. Some of the nest-builders are really excavators; they dig out
their nests in a tree or bank. The woodpeckers and the bee-eaters are
examples of these. The rest of the nest-builders actually construct their
nurseries. These buildings are of various degrees of complexity. Crows,
doves, birds of prey, herons, and a few other families are content with a
mere platform of sticks and twigs, which rests in the fork of a tree, or
on a ledge or other suitable surface. The birds which build primitive
nests of this description are not put to the trouble of seeking or
manufacturing any cohesive materials. It is only when the nest takes some
definite shape and form that means have to be found of binding together
the materials of which it is composed, and of attaching the whole to that
which supports the nest. In such cases the component materials are either
woven or cemented together. It is among the woven nests that we find the
highest examples of avian architecture. The homes of the weaver-bird
(_Ploceus baya_) and of the Indian wren-warbler (_Prinia inornata_) are
constructed with a skill that defies competition. But it is not with
these wonderful nests that we are concerned to-day. It must suffice to
say that woven nests have to be supported; they cannot float in the air.
There are various methods of supporting them. The nest may be firmly
wedged into a forked branch. It may be bound to its supports, as in the
case of the nest of the king crow (_Dicrurus ater_). The supporting
branches may be worked into its structure, as is done by _Prinia
inornata_. The nest may hang, as does that of _Ploceus baya_. It may be
cemented to its support, as in the case of the nests of the various
swifts; or it may rest on supporting fibres which are slung on to a
forked branch, just as a prawn net is slung on to its frame. The golden
oriole (_Oriolus kundoo_) resorts to this ingenious device.
Coming now to those nurseries in which the building materials are
cemented together, we must first consider the nests of the swallows and
swifts. These birds secrete a very sticky saliva, which quickly hardens
when it is exposed to the air. This constitutes an excellent cement.
Watch a swift working at its nest under the eaves of a house. It flies to
it with a feather or piece of straw carried far back in the angle of its
mouth, hangs itself by means of its four forwardly directed toes on to
the half-completed nest, which is stuck on to the wall of the house, and,
having carefully placed the feather or straw in the required position,
holds it there until the sticky saliva it has poured over it has had time
to harden and thus firmly glue the added piece of material to the nest.
The bits of straw, feathers, etc., may be said to constitute the bricks,
and the saliva the cement of the swift’s nest. Some swifts build their
nests exclusively of their saliva. These constitute the “edible birds’
nests” of commerce, and may be likened to houses built entirely of
cement. The martin (_Chelidon urbica_), the common swallow (_Hirundo
rustica_), and the wire-tailed swallow (_H. smithii_) construct their
nests of clay and saliva. They repair to some puddle and there gather
moist clay, which they stick on to some building, so as to form a
projecting saucer-shaped shelf. In this the eggs are laid. But nature has
not vouchsafed sticky saliva to all birds, so that many of them have to
find their cement just as they have to seek out the other building
materials they use.
The chestnut-bellied nuthatch (_Sitta castaneiventris_), which nestles in
holes in trees, fills up all but a small part of the entrance with mud
“consolidated with some viscid seed of a parasitical plant.”
The hornbills close up the greater part of the orifice of the hole in
which they nest with their droppings mixed with a little earth.
Hume informs us the rufous-fronted wren-warbler (_Franklinia buchanani_)
utilises a fungus as its cement. “In all the nests that I have seen,” he
writes, “the egg-cavity has been lined with something very soft. In many
of the nests the lining is composed of soft, felt-like pieces of some
dull salmon-coloured fungus, with which the whole interior is closely
plastered.”
The cement which is most commonly used is cobweb. I do not think that I
am exaggerating when I say that cobweb enters extensively into the
structure of the nests of more than one hundred species of Indian birds.
What birds would do without our friend the spider I cannot imagine.
The nest of some birds is literally a house of cobwebs. The beautiful
white-browed fan-tail fly-catcher (_Rhipidura albifrontata_) is a case in
point. Its nursery is so thickly plastered with cobweb as to sometimes
look quite white. It is a tiny cup that rests on a branch of a bush or
small tree, and is composed of fine twigs and roots, which are cemented
to the supporting branch and to one another by cobweb. This the bird
takes from the webs of those trap-door spiders which weave large nets on
the ground.
Utterly regardless of the feelings of the possessor of the web, the
fly-catcher takes beakful after beakful of it, and smears it over the
part of the branch on which the nest will rest. It then sticks to this
some dried grass stems or other fine material, next adds more cobweb, and
continues in this manner until the neat little cup-shaped nest is
completed. This, as I have already said, is thickly coated exteriorly
with cobweb to give it additional strength.
The sunbirds or honeysuckers make nearly as extensive use of cobweb in
nest construction as do the fan-tailed fly-catchers. Loten’s honeysucker
(_Arachnechthra lotenia_) seeks until it finds a large spider’s web
stretched horizontally across some bush; it then proceeds to build its
nursery in the middle of this. As the material is added the nest grows
heavier, and thus depresses the middle of the web until it at last
assumes the shape of a V, in the angle of which the mango-shaped nest is
situated. The nursery is thus suspended from the bush by the four corners
of the cobweb.
A spider’s web looks such a flimsy affair that it does not seem possible
that it could support a nest peopled by a number of birds. Sometimes the
nest derives additional support by being attached to other branches.
Moreover, a tiny creature such as a sunbird is almost as light as the
proverbial feather. Then cobweb is exceedingly elastic, and, considering
its attenuity, is able to support a surprising amount of weight. It
occasionally happens that the common garden spider (_Epeira diadema_) is
not able to find a _point d’appui_ to which it can attach the lower part
of its web; it then utilises a stone (which may be as much as a
quarter-inch in each dimension) as a plummet to make the nest taut. This
comparatively heavy stone hangs by a single thread.
I have sometimes amused myself by testing the strength of a strand of
cobweb stretched across a path, by hanging bits of match or other light
material on it. In one experiment a gossamer thread, thirty feet in
length, stretched across a road, bore the weight of five blades of grass
which were hung upon it. The sixth blade proved to be the last straw that
broke the camel’s back.
The strength of cobweb is proved by the fact that many of the birds that
build hanging nests use it as cement to attach them to the supports from
which they are suspended. The Indian white-eye (_Zosterops palbebrosa_)
fixes its tiny oriole-like nest to the supporting branches, not by
fibres, but by cobweb. In the same way the yellow-eyed babbler
(_Pyctorhis sinensis_), whose nest is shaped like an inverted cone,
attaches this by cobweb to the stems of the crop in which it is situated.
The common honeysucker (_Arachnechthra asiatica_), whose nest looks like
a tangle of dried twigs and other rubbish, uses much cobweb in the
construction thereof. The little nursery is suspended by means of cobweb
from some projecting branch of a bush, and the various materials which
compose it are stuck together with spider’s web; but in this case some
sticky resinous substance is usually used in addition to the cobweb.
The tailor-bird (_Orthotomous sutorius_) always uses cobweb to draw
together the edges of the leaf or leaves that compose its nest. Having
made a series of punctures along the edges of the leaf to be utilised, it
procures some cobweb, and, having attached it to one edge of the leaf,
carries the strand across to the other edge and, before attaching it to
this, pulls it so tightly as to draw the two edges together. When the
nest has taken its final shape the bird strengthens the first attenuated
strands of cobweb by adding more cobweb or some threads of cotton.
Many birds which weave their nests plaster the exterior more or less
thickly with cobweb so as to add strength to the structure.
It would be wearisome to detail all the kinds of nest into the
composition of which cobweb enters. Sufficient has been said to show that
this very useful substance is the favourite cement of bird masons.
XXXII
INDIAN FLY-CATCHERS
There exist in the Indian Empire no fewer than fifty-one species of
fly-catcher. This fact speaks volumes for the wealth of both the bird and
the insect population of India. Fly-catchers are little birds that feed
exclusively on insects, which they secure on the wing. Their habit is to
take up a strategic position on some perch, usually the bare branch of a
tree, whence they make sallies into the air after their quarry. Having
secured the object of their sortie—and this they never fail to do—they
return to their perch. A fly-catcher will sometimes make over a hundred
of these little flights in the course of an hour; the appetite of an
insectivorous bird appears to be insatiable. All fly-catchers obtain
their food in this manner, but all birds which behave thus are not
members of the fly-catcher family. As fly-catchers are characterised by
rather weak legs, and, in consequence, do not often descend to the
ground, they are of necessity confined to parts of the country well
supplied with trees. Thus it comes to pass that the great majority of
fly-catchers are found only in well-wooded hill tracts. Four or five
species, however, occur commonly in the plains. With two of these—the
glorious paradise fly-catchers (_Terpsiphone_) and the very elegant
fan-tail fly-catchers (_Rhipidura_)—I have dealt in my former books. I
therefore propose to confine myself to some of the many other species. Of
these last, the brown fly-catcher (_Alseonax latirostris_) is the one
most frequently met with in the plains. This is the most inornate of all
the fly-catchers. As its name implies, brown is its prevailing hue. Its
lower parts are, indeed, whitish, and there is an inconspicuous ring of
white feathers round the eye, but everything else about it is earthy
brown. It is the kind of bird the casual observer is likely to pass over,
or, if he does happen to observe it, he probably sets it down as one of
the scores of warblers that visit India in the cold weather. It is only
when the bird makes a sudden dash into the air after an insect that one
realises that it is a fly-catcher. The brown fly-catcher is an
Ishmaelite. It seems never to remain for long in one place, and, although
it may be seen at all times of the year, its nest does not appear ever to
have been found in this country.
A more ornamental fly-catcher which occasionally visits the plains is the
grey-headed fly-catcher (_Culicapa ceylonensis_). In this species the
head, neck, and breast are ash-coloured, the wings and tail are dark
brown, the back greenish yellow, and the lower parts dull yellow. This
fly-catcher is common both in the Nilgiris and the Himalayas. It has the
usual habits of the family. Like the majority of them it is no songster,
although it frequently emits a cheeping note. Its nest is a very
beautiful structure, a ball of moss which is attached to a moss-covered
tree or rock, more often than not near a mountain stream.
Fly-catchers usually nidificate in the neighbourhood of water, because
that element favours the existence of their insect food.
_Siphia parva_—the European red-breasted fly-catcher—is a species which
visits the plains of India in the cold weather, but not many individuals
penetrate so far south as Madras. This bird is easily recognised, since
the cock bears a strong likeness to the familiar English robin
red-breast. I may here mention that an allied species—the Indian
red-breasted fly-catcher, _S. hyperythra_—summers in Kashmir and winters
in Ceylon, but, curiously enough, it has not been recorded from the
plains of India. It would thus seem to fly from Kashmir to Ceylon in a
single night. Even so, it would be very extraordinary if an occasional
individual did not fail to perform the whole journey in so short a space
of time; therefore, this species should be watched for in South India in
spring and autumn. It is easily distinguished from allied species by a
black band which surrounds the red breast and abdomen.
As it is impossible to detail in one brief essay all the species of
fly-catcher found in the Indian hills, I propose merely to mention those
that are most common in the Nilgiris and the Himalayas, and then to make
a few observations on fly-catchers in general. In addition to the
fan-tail, the grey-headed and the brown fly-catchers, the following
species are abundant in the Nilgiris: Tickell’s blue fly-catcher
(_Cyornis tickelli_), the Nilgiri blue fly-catcher (_Stoparola
albicaudata_), and the black and orange fly-catcher (_Ochromela
nigrirufa_). In the Himalayas, the paradise fly-catcher is common in
summer at lower altitudes. Above 6000 feet elevation the following are
the species most commonly seen: the grey-headed fly-catcher, the
white-browed blue fly-catcher (_Cyornis superciliaris_), and the
beautiful verditer fly-catcher (_Stoparola melanops_), which is no mean
songster.
