A German naturalist, Adolf Müller, of Gladenbach, writing in a German

periodical, “Der Zoologische Garten,” in October, 1868, has given a

curious account of the conduct of two young Cuckoos, which were hatched

in the nest of a Robin. A translation of this account was published in

“The Field” of Nov. 21, 1868, and it will be unnecessary therefore to

give more than the merest outline of the facts detailed in it.

Two young Cuckoos, five or six days old, were found in a Robin’s nest,

four Robin’s eggs lying on the heath before the nest. The two birds were

extremely restless, striving to push each other out of the nest, the

smaller one always the more active. Herr Müller placed the smaller on

the back of the larger one, which immediately began to heave it upwards,

and, thrusting its claws into the moss and texture of the nest, actually

succeeded in pushing it to the edge of the nest and about four inches

further amongst the heath stems. After every contest which was observed

both birds contrived to creep back again into the nest. Ultimately the

larger one was found lying dead outside the nest, while the Robin was

sitting on the smaller bird and the eggs, which had been replaced.

The latest contribution on the subject is that of Mr. Gould, who in his

splendid folio work on “The Birds of Great Britain,” expressed himself a

disbeliever in the popular story. He has since found reason to change

his opinion, for in his recently published octavo “Introduction” to that

work he says: “I now find that the opinion ventured in my account of

this species as to the impossibility of the young Cuckoo ejecting the

young of its foster parents at the early age of three or four days is

erroneous; for a lady of undoubted veracity and considerable ability as

an observer of nature, and as an artist, has actually seen the act

performed [he seems to overlook the circumstance that others had

previously seen it], and has illustrated her statement of the fact by a

sketch taken at the time, a tracing of which has been kindly sent to

me.”

This tracing he has reproduced as an engraving in the “Introduction”

referred to, and as he has been good enough to allow me the use of the

wood block to illustrate the present remarks, the reader may consider

himself in possession of a fac-simile sketch from nature.

The following is the account given by Mrs. Blackburn (the lady referred

to) of the circumstance as it came under her observation:[105]—

“The nest which we watched last June, after finding the Cuckoo’s egg in

it, was that of the Common Meadow Pipit (Titlark, or Moss-Cheeper), and

had two Pipit’s eggs, besides that of the Cuckoo.

“It was below a heather bush, on the declivity of a low abrupt bank, on

a Highland hill-side, in Moidart. At one visit the Pipits were found to

be hatched, but not the Cuckoo.

[Illustration: Cuckoo in nest]

“At the next visit, which was after an interval of forty-eight hours, we

found the young Cuckoo alone in the nest, and both the young Pipits

lying down the bank, about ten inches from the margin of the nest, but

quite lively after being warmed in the hand. They were replaced in the

nest beside the Cuckoo, which struggled about till it got its back under

one of them, when it climbed backwards directly up the open side of the

nest, and hitched the Pipit from its back on to the edge. It then stood

quite upright on its legs, which were straddled wide apart, with the

claws firmly fixed half-way down the inside of the nest among the

interlacing fibres of which the nest was woven; and, stretching its

wings apart and backwards, it elbowed the Pipit fairly over the margin

so far that its struggles took it down the bank instead of back into the

nest.

“After this the Cuckoo stood a minute or two, feeling back with its

wings, as if to make sure that the Pipit was fairly overboard, and then

subsided into the bottom of the nest.

“As it was getting late, and the Cuckoo did not immediately set to work

on the other nestling, I replaced the ejected one and went home. On

returning next day both nestlings were found dead and cold, out of the

nest. I replaced one of them, but the Cuckoo made no effort to get under

and eject it, but settled itself contentedly on the top of it. All this

I find accords accurately with Jenner’s description of what he saw. But

what struck me most was this: The Cuckoo was perfectly naked, without a

vestige of a feather, or even a hint of future feathers; its eyes were

not yet opened, and its neck seemed too weak to support the weight of

its head. The Pipits had well-developed quills on the wings and back,

and had bright eyes, partially open; yet they seemed quite helpless

under the manipulations of the Cuckoo, which looked a much less

developed creature. The Cuckoo’s legs, however, seemed very muscular;

and it appeared to feel about with its wings, which were absolutely

featherless, as with hands, the ‘spurious wing’ (unusually large in

proportion), looking like a spread-out thumb. The most singular thing of

all was the direct purpose with which the blind little monster made for

the open side of the nest, the only part where it could throw its

burthen down the bank.”

Notwithstanding the objections put forward by sceptics, it is

impossible, after reading the evidence of the above-named independent

observers, to doubt that the young Cuckoo is capable of doing all that

has been attributed to it in the way of ejectment. But it is still very

desirable that some competent anatomist should examine and report upon

the arrangement and development of the nerves and muscles, which must

differ very considerably from those which are to be found at the same

age in the young of other insessorial birds.

[Illustration: WRYNECK]

THE WRYNECK.

(_Jynx torquilla._)

Following closely in the wake of the Cuckoo, if not occasionally

preceding it, comes the Wryneck, or Cuckoo’s-mate, as it is popularly

called from the habit referred to. In some respects it is a very

remarkable bird, for not only is its appearance quite unlike that of any

other of our summer migrants, but its actions and habits are also

totally different. In size no larger than a Skylark, it at once attracts

attention by the beauty of its plumage which, although of sombre hue, is

prettily variegated with greys and browns of different shades, here and

there relieved with black. The under parts, of a soft grey inclining to

yellow, are transversely bound with delicate wavy lines. Although for

the purpose of comparison, this species may be likened in point of size

to the familiar Lark, its structure and habits fit it for a very

different mode of life. It is a scansorial or climbing bird, like the

Woodpeckers, with toes directed two in front and two behind; hence the

term yoke-footed, which has been applied to the particular group of

birds in which it is included. The genus to which this bird belongs has

generally been associated with the genus _Picus_, to which it

undoubtedly bears some affinity. The extensibility of the tongue is the

chief character which they have in common, but in the one the extremity

is barbed, in the other it is smooth. The fourth toe in the Woodpecker

is directed somewhat outwards and backwards, whereas in the Wryneck its

natural position is directly backwards, parallel to the first. The bill

of the latter more nearly resembles that of _Picus_ than that of

_Cuculus_, although it is not wedge-shaped at the point. On the other

hand the tail has no resemblance to that of the Woodpecker. The genus

_Jynx_, therefore, seems to stand between these two genera and to form

as it were their connecting link.

The colour of the plumage so closely assimilates to that of the bark and

boughs of trees, that it is often difficult to detect the bird when in

close proximity to such surroundings. But although the Wryneck may be

considered as strictly a woodland bird, adapted by its peculiar

structure to climbing the boles of trees and probing the interstices of

the bark for lurking insects, it nevertheless finds a considerable

portion of its food on the ground, and it especially affects the

neighbourhood of ant-hills, where it preys largely on those insects and

their larvæ. In this employment its remarkable tongue, like that of the

Woodpecker’s, is of great service. It is long and slender, with a horny

point, and is capable of being protruded for more than twice the length

of the head, in consequence of the extreme elongation of the two

branches of the flexible or hyoid bone, as it is termed, which supports

the tongue, curling round at the back of the head, dividing and passing

over each eye, at the forehead, where the branches reunite and extend to

the base of the upper mandible. Two long salivary glands, situated

beneath the tongue, open into the mouth by two ducts, and secrete a

viscid fluid which covers the tongue, and thus causes ants, larvæ, and

other small insects forming the food of this species to adhere to it.

Where the soil is loose the tongue is thrust into all the crevices to

rouse the ants, and for this purpose the horny extremity is very

serviceable as a guide to the tongue. The peculiar habit which the bird

has of twisting the neck with a slow undulatory movement, like that of a

snake, has obtained for it the name of Wryneck, not only in England but

throughout the continent, wherever the bird is known.

Although common in the southern and south-eastern counties of England,

the Wryneck is only partially distributed in the British Islands, and

the limit of its geographical area is almost coincident with that of the

Nightingale before noticed. In the western and northern counties of

England, as well as in Wales, it is comparatively a scarce bird; in

Scotland it is very rare, and in Ireland quite unknown. Its arrival in

April is speedily announced by its loud and oft-repeated cry, which has

been likened to the syllable—“dear, dear, dear, dear, dear,” and which

resembles, though less harsh, the cry of the Kestrel.

In its mode of nidification, the Wryneck resembles the Woodpeckers,

selecting a hole in a tree wherein to deposit its eggs, which are six or

seven in number, pure white, and laid with little or no attempt at a

nest upon chips of decayed wood at the bottom of the hole. In about

three weeks the young are hatched, and both parents take their turn at

feeding them, bringing ants and their eggs in mouthfuls, woodlice, small

spiders, and other insects. The ants, which are gathered up wholesale by

means of the long glutinous tongue, which the bird darts amongst them

with great rapidity, are stored up in the mouth until the return to the

nest, when they are ejected in ball-like masses into the open gapes of

the clamorous young. The latter quickly assume their feathers, and by

the month of August are ready to leave the country with their parents

_en route_ for Africa, Asia Minor, and India, where they pass the cold

months of the year. But according to the observations of Lindermayer,

Dr. Kruper, and others, many spend the winter in Greece amongst the

olive groves, and Lord Lilford has seen it in Epirus in March and

December (“Ibis,” 1860, p. 235).

In Tangiers, Tripoli, Algeria, Egypt, Nubia, and Abyssinia, it is by no

means uncommon. It occurs also in Arabia, and according to Dr. Jerdon

(“Birds of India,” vol. i. p. 303) is found throughout India, except,

perhaps, on the Malabar Coast, where he never saw it, or heard of a

specimen being procured. He adds, “It is chiefly, perhaps, a

cold-weather visitant in the south of India; but it is found to remain

all the year further north.”

I have already touched upon the question whether any of our summer

migrants breed in their winter quarters, as well as in their summer

haunts (see p. 41), and it may be well to note here the above remark of

Dr. Jerdon, as well as the observation of Captain Loche, that the

Wryneck breeds in the forests of Algeria. It of course remains to be

shown whether the individuals which rear their young south of the

Mediterranean, ever migrate into Europe; for it is possible that Algeria

may be the northern-most limit in summer of those birds which have

passed the winter many degrees further south than have the migrants from

Europe.

[Illustration: HOOPOE]

THE HOOPOE.

(_Upupa epops._)

Amongst the large number of migratory birds which resort to the British

Islands in spring for the purpose of nidification, are a few which come

to us accidentally, as it were, or as stragglers from the main body of

immigrants which, crossing the Mediterranean from Africa, becomes

dispersed over the greater part of Europe. The Hoopoe is one of these.

Not a summer elapses without the appearance, and, I regret to say, the

destruction, of several of these beautiful birds being chronicled in

some one or other of the many periodicals devoted to Natural History. If

the thoughtless persons, whose first impulse on seeing an uncommon bird,

is to procure a gun and shoot it, would only take as much pains to

afford it protection for a time, observe its habits, describe its mode

of nesting and manner of feeding its young, they would do a much greater

service to ornithology by recording the result of their observations,

than by publishing the details of a wanton destruction.

That the Hoopoe will breed in this country, if unmolested, is evidenced

by the recorded instances in which it has done so where sufficient

protection has been afforded it during the nesting season. Montagu

states, in his “Ornithological Dictionary,” that a pair of Hoopoes began

a nest in Hampshire, and Dr. Latham has described a young Hoopoe which

was brought to him in the month of June. A pair frequented Gilbert

White’s garden at Selborne; and another pair nested for several years in

the grounds of Pennsylvania Castle, Portland.[106] Mr. Jesse states[107]

that some years ago a pair of Hoopoes built their nest and hatched their

young in a tree close to the house at Park End, near Chichester; and

according to the observations of Mr. Turner, of Sherborne, Dorsetshire,

the nest has been taken, on three or four occasions, by the schoolboys

from pollard willows on the banks of the river Lenthay. The birds were

known to the boys as “Hoops.”

In the same county, on the authority of the Rev. O. P. Cambridge, a pair

of Hoopoes are reported to have bred at Warmwell. The Rev. A. C. Smith,

of Calne, Wilts, says that a nest, containing young birds, was taken

many years ago in his neighbourhood; and another nest, according to Mr.

A. E. Knox, was found at Southwick, near Shoreham. Canon Tristram states

that the Hoopoe has bred at least on one occasion, in Northamptonshire.

Mr. Howard Saunders informs me that many years ago a pair of Hoopoes

took possession of a hole in a yew tree in the shrubbery of a garden at

Leatherhead, and reared their young in safety. He afterwards saw both

old and young birds strutting about on the lawn. I have seldom met with

this bird in England, and then only on the coast in September, when the

beauty of its plumage had become faded, and the feathers ragged, and it

was about to emigrate southwards for the winter. But on the continent,

and more particularly in France, I have had many opportunities of

observing it, and noting its actions and habits. In its movements on the

ground it struck me as resembling the Rook more than any other bird I

could think of at the time; the same stately tread and gentle nodding of

the head, every now and then stopping to pick up something. It does not

carry the crest erect, but inclining backwards, and is less sprightly in

its movements generally than I had previously supposed. On the wing it

at first sight reminds one of a Jay, the principal colours being the

same, viz., black, white, and pale cinnamon brown; but the distribution

of colour is different, and the flight is not so rapid, and more

undulating. The wings are large for the size of the bird, and the

first-quill feather being much shorter than the second, the wing has a

rounded appearance which makes the flight seem heavier.

It is a shy bird, taking wing on the least alarm, except when surprised

by a hawk or other large bird, when, according to the observations of

the German naturalists, Naumann and Bechstein, it resorts to a very

singular expedient to protect itself. It squats upon the ground, spreads

out its tail and wings to their fullest extent, bringing the primaries

round so as almost to meet in front, and throws back its head and bill,

which it holds up perpendicularly.[108] So long as danger threatens, it

remains in this odd position, probably to deceive the enemy; for when

thus spread out, at a little distance it looks more like an old

parti-coloured rag than a living bird.

The Hoopoe lives a good deal on the ground where it finds its chief

food, which consists of beetles of various kinds, and their larvæ,

caterpillars, and ants. It is especially partial to dung-beetles, and

may often be seen in search of them upon the roads, where it is also

fond of dusting after the manner of a Skylark. But besides picking up a

great deal of food from the surface, it also probes beneath the soil

where the nature of the ground admits of this, and secures many a worm

and lurking grub by means of its long and slender pointed bill. It

swallows a beetle or other small morsel just as the Hornbills in the

Zoological Society’s Gardens swallow the grapes which are thrown to

them, that is to say, it seizes it first between the tips of the

mandibles, then throwing the head back suddenly, and opening the bill at

the same instant, the food is jerked into the gullet with great

precision, and disappears. When it seizes a worm, however, the process

is somewhat different. It bruises it by beating it against the ground,

pinches it all over between the mandibles, and finally swallows it

lengthwise with sundry jerks of the head.

In other respects, as well as in the mode of taking their food, the

Hoopoes resemble the Hornbills. They build in holes of trees as the

latter are known to do, and the hens sit upon the eggs without

interruption until they are hatched, the males, as in the case of the

Hornbills, bringing food and feeding them from the outside of the hole.

The eggs, which are generally five or six in number, are elongated,

nearly oval, and of a greenish grey colour. The young when first hatched

are naked, but soon get covered with small blue quills from which the

feathers sprout. They are unable to stand upright until nearly fledged,

but crouch forward and utter a hissing noise. Their crests are soon

developed, but their bills do not acquire their full length until the

following year.

Lord Lilford states that although the Hoopoe as a rule prefers a hole in

an old ash or willow tree for nesting in, he has seen a nest on the

ground under a large stone, others in holes on the sunny side of mud or

brick walls, one in a fissure of limestone rock, and another in a small

cavern.

Dr. Carl Bolle has observed that in the Canaries, where trees are

scarce, the Hoopoe breeds in holes of the stone walls and clefts of the

rocks.

During his residence in China, where this bird is common, Mr. Swinhoe

was surprised to find that it often breeds in the holes of exposed

Chinese coffins, whence the natives have a great aversion to them,

branding them as “Coffin-birds;” and the Russian naturalist Pallas once

found a nest of the Hoopoe, containing seven young ones nearly ready to

fly, in the decomposed abdominal cavity of a dead body!

The note of the Hoopoe is very remarkable, and not to be mistaken for

that of any other bird with which I am acquainted. It sounds like the

syllables “hoop-hoop,” “hoop-hoop,” frequently repeated, and in the

quality of its tone approximates to the call of the Cuckoo, but the

second note is a repetition of the first instead of being, as in the

case of the Cuckoo, a third below it. Old authors affirmed that this

peculiar sound was produced by the bird distending its cheeks with air,

and tapping its bill upon the ground, thereby causing the notes to

escape as it were spasmodically. This curious statement has received

some confirmation from the observations of Mr. Swinhoe.[109] He says:

“To produce these notes, the bird draws the air into its trachea, which

puffs out on either side of the neck, and the end of the bill is tapped

perpendicularly against a stone or the trunk of a tree, when the breath

being forced down the tubular bill produces the correct sound.” He adds,

however, that he has observed a Hoopoe perched upon a hanging rope, and

uttering its well-known cry without any tapping of the bill.

I cannot help thinking that a bird observed in the act of calling

_whilst picking up food_, as many species do, has given rise to the

notion that the sound is _produced_ by tapping, whereas in truth it

precedes and follows the movement. The only motion that I could ever

detect in a Hoopoe whilst calling was a nodding of the head, and a

depression of the crest-feathers.

From the accounts which have been handed down to us by old authors, and

the numerous specimens which may be seen preserved in old collections,

it would appear that the Hoopoe was formerly much more plentiful in

England than it is at the present day. The decrease in its numbers

probably arises from two causes, viz., the clearance of forest land,

entailing the destruction of many old trees which were once attractive

as nesting places,[110] and the increased use of fire-arms which

unfortunately results in the destruction of many of these beautiful

birds, at a time when they are just about to pair and commence

nidification.

The period of its migration into Europe in the spring sets in early in

April. The late Commander Sperling, when stationed with his vessel in

the Mediterranean, frequently met with Hoopoes at sea during their

passage. In the English Channel on the 15th April, 1854, a Hoopoe after

flying two or three times round a steamer entered one of the windows of

the saloon and was taken, apparently exhausted with fatigue. Another, on

the 21st April, alighted on a mackerel-boat between the Eddystone

Lighthouse and Plymouth Breakwater, in an exhausted state, and allowed

itself to be taken.

The average date of arrival in England may be said to be the third week

in April, when the species is more frequently met with in the eastern

and south-eastern counties, although it wanders inland to a considerable

distance. It is regarded by Mr. R. Gray[111] as a straggler to Scotland;

and Mr. Thompson remarks[112] that in Ireland it has appeared

occasionally in all quarters of the island.

As autumn approaches, these birds, or such of them as have contrived to

escape destruction, begin to move southwards for the winter, and passing

gradually down to the Mediterranean, are observed for some days about

the groves and olive gardens near the sea before they finally cross

over. In this way they return to their winter haunts about the end of

August or beginning of September. Throughout Southern and South-eastern

Europe, as well as in Siberia and North-eastern Africa, the Hoopoe

breeds commonly; but in the northern and western parts of the last-named

continent it is chiefly a winter visitant. The Siberian birds, probably,

and not the European ones, migrate to India and China for the cold

season, and some remain to breed in both these countries. Those which

have passed the summer in Europe, as already shown, spend their winter

in Africa.

Occasionally a Hoopoe has been observed in winter in the British

Islands, but so rarely as to make the occurrence a matter of note. An

instance or two of this kind in Norfolk has been noticed by Hunt in his

“British Birds” (vol. ii. p. 147); and Mr. R. Gray, in his “Birds of the

West of Scotland,” p. 198, refers to two which were killed near Glasgow,

in different years, so late as the month of October.

The late Sir William Jardine informed me that two were shot in

Dumfriesshire in the winter of 1870-71.

The most perfect specimen of the Hoopoe I have ever seen is one in my

collection, which was shot at the Dell, a piece of water near Whetstone,

Middlesex, on the 25th April, 1852. It has no less than twenty-two crest

feathers the longest two inches in length, arranged in two parallel

rows, with the upper surfaces outwards, and of a pale cinnamon colour

broadly tipped with black. The other portions of the plumage are equally

perfect and bright in colour.
