CHAPTER XII

Watching Blackbirds, Nightingales, Sand-martins, etc.

Birds are never more charming to watch than when they are building

their nests, and, of all our British nest-builders, few, perhaps,

build more charmingly than the blackbird. It is the hen alone that

collects and shapes the materials, but the male bird accompanies her in

every excursion either to or from the nest. When she is busied in its

construction he sits in a tree or a bush near by, and, on her leaving

it for fresh leaves or moss, follows her in a series of flights from

tree to tree, and, finally, down on to the ground, where the two hop

about, closely in each other's company. It is seldom that the hen flies

at once to where she means to collect her materials, though time after

time it may be at the same place. Usually she flies past the tree--all

beautiful in spring and early morning--where the cock sits, and perches

in another at some little distance beyond it. There you may lose sight

of her, but as soon as you see her handsome gold-billed mate leave his

bower and fly to hers, you know that she has flown on, and is now

perched somewhere else. Thus you may see them glancing through the

greenwood, she usually leading, but sometimes each alternately passing

the other. Coming to the collecting ground--for there is usually

some spot more liked by the birds than any other--the hen flies down

and begins to hop about, making, at intervals, little dives forward

with her bill, till she has collected some moss, dry grass, or quite

a little bundle of dead brown leaves. The male bird follows her all

about, hopping where she hops, prying where she pries, and seeming

to make a point of doing all that she does except actually collect

material for the nest, and this, in my experience, he never does do.

Then, the one laden, the other empty-billed, they both fly back in just

the same way, and the cock will sit again, often in the same tree,

whilst the hen adds her store to the growing bulk of the nest. I have

watched a pair make thirty-one excursions to and from the nest between

five and eight o'clock in the morning. By half-past eight or nine the

building would cease, nor would it be commenced again during the rest

of the day.[22]

[22] As far as I could ascertain this by coming a few times at

intervals.

Anything lovelier than the picture presented by the two birds thus

busied together in the early, dewy morning, it would be difficult to

imagine. It would arouse the enthusiasm of all except very dull people,

and is even a prettier thing to see, I think, than when both male and

female work jointly. In the latter case the straightforward business

element predominates, but here, the attendance of the male bird upon

the female, and his evident pleasure in such attendance, his anxious

interest in what she is doing, and joy in seeing her do it, throws a

more romantic element into the picture. It is that which makes me

extend the word "busy" to both the birds, for the cock is as busy in

escorting and observing the hen as she is in collecting the materials

for and building the nest; whilst that she loves him and is cheered by

his society, his presence making "the labour she delights in" still

more a joy, is also apparent. These are sweet and lovely things to

see, and the joy of them is the greater that the emotions concerned

are so direct and simple, without those windings and ambiguities,

those side-issues and counter-currents which, with us, lead direct

to grey hairs, and novels not by Scott or Jane Austen. Here are no

troublesome entanglements, no tiresome perplexities, no conscientious

sacrificings of the best beloved to every other possible person and

consideration. All is sweet simplicity and giving up to--not giving

up. These blackbirds love each other and carry it through. They do not

think of twenty other blackbirds and fail or come in draggle-tail at

the end--as in the novels. Nor are they bothered with "questions." It

is refreshing--most refreshing--to see them--like a sparkle of Gilbert

after some very "serious" dulness.

Roughly speaking, there are three stages in the building of a

blackbird's nest. The first or foundation stage consists of moss,

sticks, and leaves; the second is the mud stage; and the third, that of

dry grass and fibre, with which the interior is finally lined. The nest

of the blackbird differs, in this respect, from that of the thrush.

The latter bird, as is well known, lays its eggs in a smooth plastered

cup formed, not of mud, as one would think, but of rotten wood and

cow-dung. The blackbird, after having collected all the moss and

leaves that it deems necessary and made therewith the mass and bulk of

the nest, resorts to some little ditch or sluggish stream and trowels

up from its margin mud indeed, but not mud alone, for there is amidst

it--generally, if not always--a certain proportion of the fibrous roots

or rootlets of mud-loving aquatic plants. Of these, the bird can take a

firm hold with its bill, and as the mud adheres to the fibrous network,

it is enabled to carry a considerable quantity of it at a time, though

a greater or less amount often falls off during the passage. It is in

this circumstance, as I believe, that one can read the origin of the

"extraordinary habit," as Darwin calls it, of a bird's plastering the

inside of its nest with mud. It is the thrush to which he alludes,

but the description applies equally, and, in respect of the material

employed, still more accurately, to the blackbird. At a certain point

in its construction, the nest of the latter would be mistaken by

anyone without previous experience, for that of a thrush, the cup

being as deep and perfect in form and the workmanship not noticeably

inferior. It is, however, of a darker colour--black, or approaching

to black--though this may vary, according to locality. Over the whole

surface are seen the scorings of the bird's beak, which seems to have

been used as a trowel. But now, if the nest had been examined a day or

two before, its interior, and, especially, the bottom of it, would have

been found to be composed of a dank moist mass of vegetation, largely

consisting of small water-plants, both the green part and the roots, to

the many fibres of which latter a quantity of mud was adhering. Here,

then, we read the whole story. Fibrous material was needed on general

principles by the female blackbird, and she found it in the spreading

network of rootlets, belonging to water-loving plants that grew in

little rills and ditches, near about her bosky brakes. But to this, mud

clung, and, in consequence, there came to be a good deal of the latter

in the cup of the nest. Something must be done with it. She began to

daub and press it, and, as she became, gradually, more and more a

plasterer, mud seemed more and more the proper sort of material to use,

till, at last, she sought it for itself alone, utilising the fibres

which bound it together, and which had, at first, been what, alone, she

sought, as a means of conveying it. But when the mud, thus brought,

had been thoroughly smoothed and plastered, so that the nest seemed

perfect and "a thing complete," like the thrush's, there would still

be something more to be done, for she--our hen blackbird--had always

been accustomed to work in stages, and the final or grass-thatching

stage had not yet been entered upon. Therefore, she would cover up and

entirely conceal all her fine plaster-work, so that no one, seeing

the finished nest, would imagine that it existed in any part of it.

But will she always do this? I cannot think it, for she is a bird of

sprightly intelligence, and I believe that, like the thrush, she will

some day find out that the neatly-plastered cup of mud does quite well

enough to lay her eggs in, and that the further labour of thatching it

with grass can be very well dispensed with. Any saving of time or of

labour must be of advantage to a species in the struggle for existence,

and those birds who thatched their nests more thinly would be enabled

to lay their eggs sooner, and thus rear more offspring. In this way, as

well as on the "least action" principle, and the exercise of ordinary

intelligence, the last stage of lining the cup with grass may finally

cease. It has ceased with the thrush, but, with the thrush, there has

been a still further process of change, for it no longer plasters its

nest with mud, but with decaying wood and with cow-dung. Assuming the

ancestors of the bird to have once used mud, and lined the interior,

as does the blackbird, there does not seem to me to be any great

difficulty in explaining this change. The blackbirds that I watched

building their nest, always, when the proper period arrived, flew to

a certain part of a little muddy dyke (it is in a land of dykes that

I reside) some little way from the plantation in which the nest was

situated, and there, lying flat behind tufts and tussocks of reeds

and grass, I watched them take their mud as I have described--the

female, that is to say, but a husband much interested in seeing a baby

carried would deserve half the credit of carrying it. Now, much nearer,

probably, than this specially-resorted-to dyke was some decayed tree

or tree-trunk, whilst over the fields which it intersected and which

adjoined the plantation, cows or oxen sometimes grazed. Here, again, a

change in the working material might prove of advantage, and when once

a bird had become a plasterer, intelligence, and also haste, might lead

it to use whatever came first to hand. Bees will carry oatmeal instead

of pollen if the former be put in their way, and birds may be credited

with equal adaptability.

After watching blackbirds building, and examining the nest in its

various stages of construction, I think it much more likely that

the thrush has passed through, and then discarded, a final stage

of thatching the nest, than that it has stopped short at the stage

of plastering, and not yet got to the one of thatching or lining.

Numberless birds, including other members of this family, line their

nests with grass or other soft materials, whereas plastering is a

comparatively rare habit. It is legitimate to assume that that which

is common has preceded that which is rare. I would here point out

that whilst, in works of ornithology, reference is always made to the

strange habit which the thrush has of daubing its nest, nothing, as a

rule, is said in regard to the similar habit of the blackbird, or, if

anything is, we are told merely that mud is used to bind the materials

together. The facts, however, are as I state, and, did the blackbird

not line its nest with grass after it had so carefully plastered it

with mud brought from the waterside, it would be as noted in this

respect as is the thrush, its near relative.

I have never heard the male blackbird sing whilst thus attending the

female as she built her nest, not even when he waited for her in a

tree, during the actual time of its fashioning, though here was a

fine poetical opportunity for him. Song, it seemed, had ended when

once his bride had been won, and his rivals vanquished by it. It was

the same, to a considerable extent, with a pair of nightingales that

I watched under similar circumstances. I did, indeed, sometimes hear

the song when the bird singing was invisible, and, therefore, I cannot

say that it was not this particular one, which, for other reasons I am

inclined to think that it was. But during far the greater part of the

time, and always when I could see him, he was as silent as his mate.

It was in the early morning and not the night-time, but nightingales

sing at all hours, both of the day and night The early morning is,

indeed, a favourite time with them, and it is then, in the beginning

of spring, when nests have yet to be built and before the birds are

properly married, that one can best observe how powerful a vehicle

of hatred and rivalry their melodious strains are. I have closely

watched two rival males for nearly an hour. Let anyone refer to my

account of the rival wheatears, substitute a plantation with bush

and tangle, and the turf-bordered roadside adjoining, for the open,

sandy warrens, and song--but much more frequently indulged in--for the

little frenzied dancings,[23] and the two pictures will be identical,

or nearly so. There was the same keeping close to, yet not appearing

to follow, each other, the attending to each other's motions without

seeming specially to watch them, the drawing near and, then, getting

apart, only to approach again, the little bursts of fury--but here,

mostly, harmonious--preceding each engagement, and surmounting, each

time, that discretionary part of valour, which, in either case, both

the birds seemed largely to possess. There were three engagements, one

bird, each time, making, as though no longer able to control itself, a

sudden little frenzied dash at the other. In no case, however, was the

conflict very severe, and the attacked bird soon flew away, with which

result the attacker seemed well satisfied. It looked more like a little

furious play than a real fight, and so, no doubt, it would, were Moth

or Cobweb to have a tussle with Peaseblossom or Mustardseed. Oberon and

Titania, indeed, "squared" so, that--

"All their elves, for fear,

Crept into acorn-cups, and hid them there."

But, here, the audience were themselves fairies, so that it was all

in proportion. Besides, the war was but of words, and, in these,

we see how the prettiness of being fairies prevails, even over the

relationship in which the two stood to each other. So it was with these

warriors; they were rivals, and stuffed full of dislike, nay hatred,

but, also, they were birds--and nightingales.

[23] The wheatears, however, sang as well as danced.

Jealousy, however, did not seem to blind them to the merit of each

other's performance. Though, often, one, upon hearing the sweet,

hostile strains, would burst forth instantly itself--and here there

was no certain mark of appreciation--yet sometimes, perhaps quite as

often, it would put its head on one side and listen with exactly the

appearance of a musical connoisseur weighing, testing, and appraising

each note as it issued from the rival bill. A curious, half-surprised

expression would steal, or seem to steal (for fancy may play her part

in such matters) over the listening bird, and the idea appeared to be,

"How exquisite would be those strains, were they not sung by----, and

yet, I must admit that they _are_ exquisite." Sometimes, however, there

would be no special response on the part of the one bird, either by

voice or attitude, whilst the other was singing. During these musical

combats I often saw a third and silent bird, hopping with demure,

modest look--by virtue of which it seemed rather to creep than to

hop--just within, or just on the outside of, this or that briery bower.

This I took to be the female, and, thinking so, it was easy to detect

a little side-glance thrown, now and again, towards one or another of

the rival suitors, in which seemed expressed the thought of a pretty,

little bird (but a lady-bird)--Bunthorne--

"Round the corner I can see,

Each is kneeling on _his_ knee."

Yet this bird may have been but another male, to whom the next unseen

notes that I heard were, perhaps, due. Always I bless those birds whose

sexes are plainly distinguishable from each other.

What was very noticeable in these nightingales--and the remark applies

to others that I have closely listened to--was that, even when not

singing against each other, they made little noises in their throats,

and these, when distinctly heard, resolved themselves into a deep,

guttural sound, which, though far from unpleasing, could hardly

be called anything but a croak. This sound, as I have noticed, is

very frequently uttered. It often commences the song, or is even

intermingled with, though it can scarcely be said to belong to, it. It

does not, in this case, diminish the beauty of the melody; yet, did

it stand alone, the nightingale would be merely a somewhat musical

croaker. Probably this is what it once has been, the low, croaking note

representing the original utterance of the bird, on which the song, by

successive variations, and choice of them on the part of the female,

has been founded. Just as in the dull plumage of female pheasants and

other birds, the males of which are splendidly adorned, or in both

the sexes of some species belonging to the same families, we see the

early state of their common, plain progenitors, so, in song-birds,

the uninspired, workaday voice of call-note or twitter--the spoken

language, as one may call it--probably represents the humble roots from

which the various trees of song, with all their diversified branchings,

and fluttering, trembling leaves, have shot up, beautifully, into

the sky. How distinct in their glories are the mature males of the

golden, silver, the impeyan, or our own common pheasant; how drabbily

alike are the females of all of them, and they themselves in their

first early plumage! So, whilst the song of the blackbird, missel,

song-thrush, fieldfare, or redwing are distinct, or suggest each

other only by their general quality, all have a high, harsh, scolding

note, which is very much the same, except in degree, though differing

in the frequency with which it is employed. Loudest and harshest of

all is the fieldfare, and this bird has hardly developed a song. The

missel, whose lay is very inferior to that of the song-thrush, is also

a frequent and loud scolder, so that many a man, whilst alone and in

the wild woods, might fancy himself within the bosom of his family.

In the common thrush, however, who is such a fine singer, this note

of fear is not nearly so often heard,[24] and its shrewish character,

though still there, has been softened. In the blackbird it is still

more rare, yet occasionally, if I mistake not, it is uttered. Again,

the well-known note of the blackbird, when disturbed (though this

varies considerably), is common, also, though in a less degree, to

the thrush,[25] so that it is possible to mistake the one bird for the

other. The same remarks apply to many finches and other small birds,

who, whilst they sing very differently, chirp and twitter in much

the same way. In all these cases, as I believe, there is a certain

correspondence between the tone or pitch of the language and that of

the song. From the low croak, as I have called it, of the nightingale,

it would be difficult to imagine the high, clear notes of the thrush

having been developed, whilst it would account for the low key in which

its own are generally pitched. What I mean is--for I am not versed in

musical terminology--that, in the nightingale's song, there are not

those high, clear, ringing notes which we hear in that of the thrush,

blackcap, skylark, and many other birds, just as in these we may listen

in vain for those richer and more liquid tones which charm us so in the

nightingale. Beautiful as these tones are, they do not, any more than

those of other birds, include every excellence, and that particular one

which they lack, being common to so many of our songsters, has come

to be something which one loves and listens for, whenever bird sings

upon bough. Partly because of this, perhaps, and partly because of the

very pre-eminence of the nightingale as a singer, I have sometimes

missed these franker, woodland-wilder strains whilst listening to its

song, in a way in which I have never missed its own more dulcet notes

from the song of lark or thrush. To say that Pindar is not _also_

Sappho is no blame to Pindar, but the short continuance and frequent

pauses in the song of the nightingale is, I think, a real fault, and

from the blame of it this _prima donna_ frequently escapes, when other

sweet, but not so all-belauded, singers are taken thereupon to task.

The poor blackbird, for instance, whose ditty is most "lovely-sweet,"

has been rated in these terms; yet, as a rule, in my experience, it

sings continuously, for a longer time than does the nightingale, whose

sometimes almost constant cessations, just when one's whole soul

cries out, like Jacques, "More, more, I prythee, more," have even an

irritating effect. Indeed, if this were always so it would be a serious

drawback, even to a song so full of excellence. But it is not always

so. Sometimes, on still, warm nights when the stars seem to breathe and

tremble and the air is like a lazy kiss (and if nights are not like

this in England, yet the song itself makes them seem so), the rich,

full notes are poured forth in a continuous stream of melody that lasts

long, and, whilst it lasts, seems to create the world afresh. Some time

afterwards, indeed, one notices that the effect has not been quite so

powerful, and that this crying want has still to be filled--but the

dear bird has done its best.

"Sie jubelt so traurig, sie schluchzet so froh,

Vergessene Träume erwachen,"

says Heine, whilst others say that the song is apt to keep them

awake at night, and, having first paid their orthodox tribute to its

supremacy over every other, will confess that they have sometimes

been obliged to open the window and throw something out to put a stop

to it. Yet the thought of how appreciative the world really is, and

how severely a heretic in such a matter may be dealt with, shall not

deter me from expressing a slight doubt as to the reality of this

supremacy--or, at least, of its extent and absoluteness. Letters each

year to the papers, from people who have been so fortunate as to hear

the nightingale long before the nightingale is accustomed to reach our

shores, have given rise to the suspicion that a thrush is, in most

cases, the real performer; and if this be so, it shows that, with many,

the comparative merits of the two depend upon its being known, for

certain, which is which. For myself, I go with the general opinion

in this respect, yet it is difficult to summon up in imagination the

effect that the clear, joyous notes of the thrush might have upon one,

did they ring out in the silence and stillness of the night. And if

this is true in regard to the thrush, does it not apply still more

to the skylark?--a bird whose lovely and long-continued outpouring,

uttered, as it is, in the day and all around--common, and therefore,

of necessity, undervalued--may yet, as it appears to me, in spite of

such a disadvantage, well challenge comparison with the song of the

nightingale itself. If we look to effect, at any rate, the former bird

seems to have inspired poets as highly, or almost as highly, as the

latter. Then we have an opinion which, perhaps, may have been that of

Shakespeare himself, who was a rare lover of music, that

The nightingale, if she should sing by day

When every goose is cackling, would be thought

No better a musician than the wren.

Now the nightingale does sing by day, and, as a matter of fact, she

_is_ then thought at least no better than the lark or thrush--in fact,

she is, like these, often not noticed at all, as I have had some

opportunities of observing. This, at least, shows that some of the

effect produced upon some of us by this bird's song, is due to that

added and exquisite poetry which night and silence gives to it. We have

no other night-singing bird who is sufficiently common, and whose song

is at the same time sufficiently distinguished for it to attract much

attention, and therefore the nightingale has this great advantage

practically all to itself. I cannot help thinking that it owes to this

that _easy_ and _unquestioned_ superiority which has been accorded to

it in popular estimation over all our other song-birds, especially such

glorious ones as the skylark, thrush, blackcap, blackbird, etc.[26]

[24] Proximity to the nest, with young, is the most frequent cause.

[25] Especially when driven from the eggs.

[26] But do the musical powers of some birds differ in different

countries? Never have I heard the two last sing here as I have in

Germany. Germans, as we know, are very musical. Have the same general

causes which ---- etc., etc.?

It will be said that I cannot appreciate the song of the nightingale,

though I am trying only properly to appreciate that of other members

of the choir. Yet if I were to say that Shakespeare was full of

imperfections, that _Julius Cæsar_ was a dull play, _King Lear_ a--I

forget what, something uncomplimentary--play, and _Richard III._ such a

one as allowed "the discerning admirer" (a _nom de plume_) to see the

author's quill-driven expression whilst writing it; that, moreover, the

seven ages of man was by no means a fine passage, and that Hamlet's

soliloquy had been much over-rated, it would not be said, on this

account, that I was unable to appreciate Shakespeare. I judge so,

because others who make these and similar statements (whether they or

the Baconians are the more pestilent, I find it difficult to decide)

pass, apparently, for the appreciative persons, which, I suppose,

they think themselves to be. Yet _how_ they can think so puzzles me,

for people who write in this way must be, really, as much bored by

Shakespeare as Shakespeare would have been by them, had an introduction

been possible--and _surely_ they must have found this out. I wish the

poor, gullible public would. How I should rejoice to be accused--yes,

and even convicted--of having no ear for the song of the nightingale,

if only it could be discovered, also, that "critics" who, with a

natural incapacity for seeing beauty _in_ beauty, yet step modestly

forward to teach us, and dance as fantastically on the body of a dead

poet as did ever a Lilliputian on that of the sleeping Gulliver, are

neither profound nor discerning nor even literary, but merely dull dogs

posing, of which sort, indeed, most "great oneyers" keep their pack.

Yet I wish they could leave the imperfections of Shakespeare (which

they discern in his master-strokes) as utterly beyond them, and busy

themselves only with the perfections of such Baviuses and Mœviuses

as it is their wont to crown. I commend them to old Bunyan with his

"'Then,' said Mr Blind-man, 'I see clearly'"--and so pass on.

The sweet song of the nightingale has caused the more stress to be

laid upon the sobriety of its colouring, the natural tendency being

to exaggerate such a contrast. But now, when one watches for the bird

in the shade of leafy thickets, the way in which it generally reveals

itself is by a sudden flash of red or chestnut brown, a bright spot of

colour which is conspicuously visible, sometimes even in the centre of

a thorn-bush, and, one may almost say, brilliantly so, as its wearer

flits amongst the trees and undergrowth. This brightness belongs to

the tail generally, but there must, I think, be either upon or just

above it--on the upper tail coverts, perhaps--a specially bright and

more ruddy-hued patch which produces the effect of which I speak; and

as nightingales habitually haunt wooded and umbrageous spots, it has

sometimes occurred to me that this has been developed as a guiding

star for one to follow another by, just as the white tail of the rabbit

is supposed to have been. I have often watched two pursuing each

other through the dim leafiness, each uttering a variant of the deep,

croaking note of which I have spoken, and which answers to the call,

chirp, or twitter amongst other birds. At such times the ruddy star or

streak has always, as I say, been most conspicuous. Independently of

this, the bird's general colouring is a pleasing olive brown which,

according to position and circumstances, has a more or less glossy

appearance, the tail having received the finest polish. By virtue

of all this, I feel sure that, to anyone who had watched and waited

for her, the nightingale would come rather as a conspicuous than a

dull-looking bird, at least amongst our smaller British birds. Tits

and chaffinches, as it seems to me, flash less as they flit through

the trees. Therefore, when I read the eternal remarks about its dull

colouring, which--and this is the bane of natural history--one writer

hands down from the mouth of another through the generations, I say

to myself that each and all of them have, either, never called upon

the bird and stayed an hour or two, or else that they have got out

of the habit--which may be also a trouble--of seeing anything other

than as "it is written." So far from the nightingale being specially

like a plain-bound book in which lovely songs are contained, to me

it seems to offer an example of a bird distinguished both by its

musical powers and--to a much lesser extent, certainly, but still

not insignificantly--by its colour also. I am thinking of its tail,

and particularly of that ruddy star or patch which, I think, is

upon it, and which, little as it may seem in a stuffed specimen or

one quite still or hardly seen, becomes a conspicuous feature under

such circumstances as I have mentioned. That this patch, or the whole

tail, means something I feel sure, but as to whether it is a badge

or an ornament--whether natural or sexual selection[27] has been at

work--I can say little. In the latter case the same force would have

been brought to bear in two different directions, and this, I think,

has been often the case with our song-birds, though it seems to have

been agreed to talk as if the opposite were. Surely the bullfinch,

chaffinch, robin, linnet, greenfinch, and others--the males of all of

which show off to some extent before the females--have been selected

(if at all) as much by the eye as by the ear of the latter; whilst the

lyre-bird of Australia offers an example of a highly adorned species

that is also conspicuously musical. The nightingale is glossy, and

sometimes--in effect, at least, and in some part of it--bright. It may

be getting brighter, but, if so, it will probably have to rival the

kingfisher before it ceases to be an encouraging symbol to those who

hide a worth which they feel beneath a want which everybody can see.

[27] Sexual, as I now believe. A recent lucky glimpse of nightingale

courtship has assured me that I have not unconsciously exaggerated.

Indeed, the ruddy glow of the broadly fanned tail, caught in the last

rays of the descending sun, could hardly be exaggerated. But the colour

was on all the rectrices. They alone, I think, are the patch, the star.

No good illustration, that I know of, exists of the nightingale; none,

at least, which at all resembles the bird as I have seen it, either

sitting, hopping, flying, singing, or silent. In natural history

books, after we have been solemnly told that the male alone sings, that

his song constitutes his courtship, and that, therefore, both the "she"

and the "melancholy" of poets are incorrect, we are generally presented

with a gaunt, scraggy-looking creature, having a woe-begone gaze

which is fixed upon the moon, towards which its neck and whole body

seem drawn out, as by some attractive force. This is the nightingale

of convention, but when I have seen it, it has always looked the

pleasingly plump, cheerful, little, brisk, active body that it really

is, and when it sang it was without any "pose," in a hunched-up,

careless-looking attitude, which had almost a feathered podginess about

it. The legs were bent, the feathers of the ventral surface touching,

or almost touching, the twig of perch, the head inclining forward at an

easy angle--a cosy, homely, happy, contented appearance. I have watched

one singing thus for some time. Not once did he rear himself up, so as

to become long, thin, and tubey--tubby he was rather, and had not the

faintest resemblance to a horrible, man-made, first-prize-for-deformity

canary bird. Just in the same way, too, he will often sing on the

ground, looking as homely and rotund as can be. True it is, as the

natural history books tell us, that no one familiar with the bird and

its habits would think of calling it or its song melancholy; therefore

(as these never add), remembering Milton's famous line, let us be

thankful that he as well as some other poets were not familiar with it.

There has long been a nightingale of poetry and literature, grown out

of its own song but having little to do with the real bird, which no

one except strict scientists--and a literary critic or two--would wish

to do away with.

With regard to the nest-building habits of the nightingale, I have only

the space to say that, as in the case of the blackbird, the female

alone collects and arranges the materials, being attended upon whilst

she does so--though, perhaps, not quite so closely--by the male. One

should be cautious, however, in concluding that such is always the case

either with this or other birds, for I have watched, for some time, one

of a pair of long-tailed tits bringing feathers to the nest, whilst the

other kept near about, with nothing in its bill. Yet ordinarily both

sexes work together in a most exemplary way. Nothing can look prettier

than these little, soft, pinky, feathery things, as they creep mousily

into their soft, little purse of a nest; nothing can look prettier than

they do as they sit within it, pulling, pushing, ramming, patting, and

arranging; finally, nothing can look prettier than they look as they

again creep out of it and fly away. Their perpetual feat of turning

round in the nest without dislocating the tail, is also one of those

few earthly things in the seeing of which one cannot weary.

I have often tried to watch these little birds collecting, so as to

see them actually find and fly away with the materials for the nest.

This, however, I found more difficult than I had expected. Every time

I saw them fly out of their nest, but in spite of stealthy following,

I generally lost them soon after they had entered a plantation close

to where, in a fir-hedge, it was. All I could be sure of was that they

flew about in different directions, sometimes into tall fir-trees,

sometimes into low tangles and bushes, sometimes, too, across the road

again and into different parts of the fir-hedge. "They keep, for the

most part, together, and whenever they are near enough I hear their

soft, subdued little 'chit chit.' As lichen, which is what they are now

principally collecting, is everywhere about on the trunks of trees,

etc., it would seem as though even a minute would be a long time for

them to take in getting a piece and returning with it, if they took it

at random; and the inference appears to be that they exercise choice

and selection, and return each time from the nest with a definite idea

of the kind of bit they want next."

I will here quote, from my notes, an observation I made on the way

these little birds roost at night, which may, perhaps, be of interest.

"On my way back I noticed some object which I took to be a dead bird,

in a tall, straggling brier-bush that formed a kind of bower, inside

which one could stand up. Thinking that this bird might have been

transfixed by a shrike, I came right under it, and, pulling down the

branches with my stick, to my astonishment the object separated and

became four little, fluttering, 'chittering,' long-tailed tits that had

been sitting wedged close together. I stood perfectly still, and after

they had 'chit, chitted' a little, and made a few little hops about the

bush, two of them came back from different directions to just the same

place, snoozled up to each other and were settled again for the night.

Very soon, a third hopped on to the two backs and pressed himself down

between them, taking no denial, and, indeed, not receiving any. The

fourth remained a little longer apart, perhaps for ten minutes, during

all which time I stood without a motion, leaning on my stick, and had,

at last, the satisfaction to see him come perching down towards the

bough, then perch on the three backs just as the third had done on the

two, and squeeze himself in amongst them so that two were on one side

of him and one on the other. All four now sat closely pressed together,

three tails projecting on one side of the twig, and the fourth on

the other. I sat down in the bush and made this entry, whilst the

birdies--surely the prettiest little ones, almost, in the world--went

to sleep.

"Next night, at about six, I took up my position in the same place, and

waited. After I had sat silently for a few minutes, I saw a pair of the

tits creeping softly about through the bushes adjacent, uttering the

little chitter in a very subdued tone. One was soon in the actual bush,

but crept out of it again and went away with the other. In another

four or five minutes, however, they both return, this time coming more

quickly and directly to the bush, when soon getting, from opposite

sides, to very much the same part of it as before, they sidle to each

other along the particular twig and then squeeze and press together so

tightly that their outline on the inner side is quite lost, like that

of a double cherry. Thus pressed and wedged, each little bird preens

itself, the two little heads moving about and seeming to belong to one

quite round body, having one tail--for their two tails are pressed,

for their whole length, together. When their heads turn inwards the

little birds appear to be caressing each other, and they must, I think,

sometimes catch hold of each other's feathers, but it is all part, or

intended to be part, of the process of preening themselves. This close

pressing seems to be a pleasure in itself, independently of the result

of warmth, for sometimes they will come unstuck, as it were, and move

a little away from each other along the twig, in order to press and

squeeze again. For a little, then, their tails may be separate, but

soon they rejoin, and, the heads being now quiet--for they are going to

sleep--and tucked closely in amongst the feathers of the breast, their

outlines, never very salient, are entirely lost, and the two birds have

become one perfectly globular one, without a head and with a long tail.

Thus two of these long-tailed tits have returned again to roost in the

same place, but the other pair do not come to the bush."

It is interesting to watch sand-martins building their nests, or,

rather, excavating the tunnels in which they will afterwards be built.

To see one enter one of these whilst it is yet but a few inches long,

and then to see the dust powdering out at the aperture, as from the

mouth of an ensconced cannon, is pretty. The sand is scratched out

backwards with the feet, but the bird also uses its bill as a pickaxe,

often making a series of rapid little blows with it, almost like a

woodpecker, the wings, which quite cover the body, quivering at the

same time. Both sexes work at the hole, and both often fly together to

it, one remaining clinging at the edge whilst the other scratches out

the sand from inside. I have seen one sitting just in the embrasure,

quietly regarding the outer world and, thus, impeding the entrance

of his partner, who at last squeezed by him with great difficulty.

Sometimes three or four will descend upon the same hole and cling

there without quarrelling; but once I saw a bird in a hole attacked by

another, who flew suddenly down upon it with a little twittering scream.

Though each pair of birds excavate their own tunnel, yet the whole

community, or, at any rate, a large proportion of it, will sometimes

work together, sweeping on to the pit's face in a body, clinging there

and burrowing, with a constant twittering, then darting off silently

in a cloud and sailing and circling round in the pit's amphitheatre,

making, when the sky is blue and the sun bright, a warm and delicious

picture such as the Greeks must have loved to gaze on.

As each bird, however, only works at his own and his partner's hole, it

is evident that this kind of social working is not the same as that of

ants or bees and other such insect communities, though it has something

of that appearance. Sometimes, for a short time, all the birds will

keep fluttering round in small circles that only extend a little beyond

the face of the cliff, not rising to a greater height than their own

tunnels in it, which they almost touch each time, as they come round.

They look like eddies in a stream beneath the bank, but are not so

silent, for all are twittering excitedly. This is an interesting thing

to see, a kind of aerial manœuvres the special cause of which, if there

be one, is not obvious.

But we will suppose that the birds are now all working, either inside

their tunnels or clinging to the face of the cliff. All at once, either

at or about the same instant of time, they all fly off, darting away,

and disseminate themselves in the sky, not one being left either in

or about the pit. In a few minutes they return, but, as is the case

with the small birds at the stacks, not in nearly so instantaneous

or simultaneous a manner; and this may be repeated for a greater or

lesser number of times. All the remarks that I have made in regard

to this phenomenon in the case of other birds apply equally here,

perhaps, indeed, to a greater extent; for, as remarked, at the moment

of each sudden exodus a certain number--sometimes about half--of these

sand-martins will be more or less hidden within the holes they are

excavating, yet out they all dart with the rest. Such sudden flights

and disappearances for a few minutes, after which all come back, strike

me as being extremely curious.

Sand-martins appear to be pugnacious. Indeed, they sometimes fight

fiercely, and I have seen two, after closing with a sharp, shrill

"charr" and struggling in the air for a little, roll down the

steep declivity of sand in which the perpendicular face of the pit

often ends. It, therefore, seems the more curious that they allow

their holes to be taken possession of by sparrows (and, also, by

tree-sparrows)--without offering any resistance. I have seen one of the

latter birds sitting quietly and calmly in the mouth of a hole, whilst

a pair of martins, who had, probably, excavated it, hovered excitedly

just over and about him, but without doing more. On many other more or

less similar occasions there has been excitement on the part of the

martins, but never an attack. Yet a tree-sparrow, or even a sparrow,

is not such a very much larger and stronger bird than a sand-martin,

and, considering the numbers of the latter, as well as their greater

activity and powers of flight, it seems to me an odd thing that they

should submit to such a usurpation so tamely. If they are not capable

of combining together in order to expel a stranger from the colony,

this speaks little for their intelligence, as they have, at least,

been generally two to one. This is a good working majority, and why,

under such circumstances, an impudent sparrow should be allowed to

sit quietly in the home whereinto he has intruded, I cannot quite

understand. But so it is, or so, at least, it has been, in my own

experience.

But I must not wrong the sparrow. Let me recall that word "impudent,"

and bury still more deeply another one, to wit, "unscrupulous," that

I was about to make use of. A sparrow, when he thus acts, is simply

annexing territory, and should have all the credit of forbearance

and self-sacrifice that belongs to such an act. His motives in doing

so are, no doubt, as creditable as are those which restrain him from

acting similarly in the case of more powerful birds, and if a doubt of

this should ever cross his mind, he need only read a newspaper or two

and listen to some speeches in "the House." He will know the integrity

of his own heart--then.

It seems wonderful that a bird of the swallow tribe--so aerial, and

without any special structural adaptation for burrowing--should be

capable of driving horizontal shafts into the face of a bank or pit,

to the length, sometimes, of seven or even, it is said, nine feet.

Though the excavations be in sand, yet this is often of a very firm

consistency, and, moreover, in many pits, the face of which had been

largely tunnelled by these birds, sand was a good deal mingled with a

fairly stiff clay. Though I have not been able to watch the process of

excavation from the commencement, so thoroughly as I should have liked

to have done, yet I have seen it to a certain extent, and I will now

quote from the notes which I took down on one such occasion:

"_May 25th._--At the pit about 7.15 A.M. A great number of birds

are working, and there is not now the same regularity in their

movements--all coming to the holes and darting away together at

intervals--as was the case, for a time, at least, when I first watched

them. Though so late, several birds are but just commencing to make

their holes, and to watch these is most interesting. Two plans seem

to be employed. In the first, the bird constantly flutters its wings,

whilst, with its feet, it at the same time clings to and scratches

the face of the cliff. Thus it partly hovers in the air, and partly

keeps itself in position with its feet, but more with the tail which

is fanned out and pressed in against the cliff, like a woodpecker's

against the trunk of the tree it is on. The second way is more curious.

The wings, here, are partly extended, but, instead of being fluttered,

they are pressed close against the sandy wall. Moving about over this,

they seem to feel for every little inequality into which they can wedge

themselves, and this the bird does, also, with his breast and the most

available part of his body, the tail being fanned and pressed to the

cliff, whilst the feet all the while are scratching vigorously. In this

way a bird will sometimes crawl, or rather wedge itself, about, over

the pit's face (which, though it may be perpendicular, or almost so, is

yet full of roughnesses and inequalities), appearing to seek either the

most yielding surface to scratch, or the best place to get fixed into

whilst scratching; and, in doing this, it leaves a track on the sand

or gravel which is quite perceptible through the glasses, and which I

believe is made by the strongly bent-in tail as well as by the feet.

It thus clings with wings, tail, and body, whilst scratching, far more

than clinging, with its claws."

"It may be asked what part in all this does the beak play? In those

birds which I have been just now watching at some twenty paces through

glasses that brought them just under my eyes, and in bright sunlight,

it seemed to play none at all. It might have been expected that, in

thus commencing, the martins would cling with the feet whilst working

with the bill. These have certainly not done so, nor have they ever

been head downwards, either now or before. I have not yet seen a

sand-martin in this position, or even approaching to it. The tail,

which is made to play so great a part, would here lose much of its

efficacy, but I do not at all think that they never do hang like

this. Within certain wide limits, birds, in my experience, act, not

uniformly, but with great variety. Probably, with longer watching, I

should have seen this attitude, and, also, the bill used as well as

the feet. Whether it is used or not in the first commencement of an

excavation, it certainly is--in the way I have described--during the

later stages."

[Illustration: _In a Sand-Pit._]

"I notice again this morning a particular hole, only about an inch

deep, and at the bottom of which there is a large stone, naturally

imbedded in the sand. No birds are now working at this, but, on the

last occasion, one was attacked several times in succession, whilst

doing so, by another. This seems as though the one bird of a pair

had thought the place unsuitable on account of the stone, and not

allowed the other to work there. Thus delicately are matrimonial

teachings conveyed amongst birds. Not one unkind word did I hear upon

either side."

"Whilst watching these sand-martins, a pretty little quadrupedal

picture was also presented to me. A rabbit, the mother of three, came

with them all from her burrow, which was near the top of the pit where

it joined the fields on one side, and couched there, delicately, in

the morning sunshine. The young ones flung themselves, all three, on

their backs, and, wedging themselves under her, two of them took their

breakfast in this position. The third one, however, having tried in

vain to get properly under her chest, made a detour, and then took her

in the flank in ordinary formation, and with successful results. To

see this with the warm, bright sand as a background, and the swallows

flying round! Lying dozing in the morning one may have pretty dreams,

but they are not often prettier than this. Blue sky, too, though it is

England, and in the depth of spring!"

I have spoken of blackbirds bringing materials thirty-one times to the

nest in the course of three hours, but this is very slow work, and

would be, even if both birds were to bring them instead of only one.

Comparatively, I mean, and the bird that I am taking as a standard

of comparison is the great crested grebe. In fifty minutes a pair of

these that I watched had brought between them one hundred cargoes of

weed, some so large that the head of the bird carrying them was almost

hidden, and some trailing on the water for a considerable way behind.

Each bird dives and comes up with its green, shining burden, with

which it at once swims to the great heap of similar material which

both have collected, and which projects a few inches above the water,

at but a short distance from the bank. The male is, if possible, more

earnest and indefatigable in the great work than even the female, and,

sometimes, he will work for a little alone, whilst she is resting. Yet,

with all this, it is apparent, at once, that she is the more effective

of the two, in her actual workmanship. She dives more quickly, and

comes up each time with a larger load, so large, sometimes, that her

head is pulled right back as she drags it along the surface of the

water. She places it, too,--if this is not fancy--a little more deftly

and quickly, showing in everything a higher degree of professional

skill, though her colleague, besides being second only to herself in

this, seems, as I say, to glow with a more ardent enthusiasm.

Huge as the mass of weeds is, which constitutes the nest of these

birds, it is collected by them in an astonishingly short space of time;

how short, I am not quite sure about, but this I can positively say,

that whereas on a certain morning I could see no trace of it above the

surface of the water, on the morning after this it was to all intents

and purposes finished, though the male bird, alone, once added very

slightly to it, not occupying more than a few minutes in so doing. As

to this, however, it can be said, in a certain sense, that the nest

never is finished, or, at any rate, not till after the female has begun

to lay her eggs. Morning after morning the male brings weeds to the

heap that his partner is sitting on, but as I had to leave early in

this stage of the bird's domestic history, I cannot tell for how long

he continues to do this. Probably, as in the case of the shag, and

also, I believe, the moor-hen, the nest is added to during the whole

time that the birds make use of it. A nest, however, may properly be

considered finished from the time that it is _en état_ to receive the

eggs and the sitting bird, and according to this, these two grebes must

have built theirs between about 8.30 A.M. on one day and 6 A.M. on the

next. Now, in my experience, these birds only work during the early

morning, from dawn or thereabouts, up to about 8 or 9. Possibly they

may begin again in the evening, or work at night, but I never saw them

building, or even (before it was finished) near the nest, at any later

time of the day. That the nest I speak of was not begun till _after_

6.30 A.M. on the one day, is practically certain, for up to that time

the birds were building another one, so that unless, as I say, they

worked on the evening of that day, or in the night-time, they must have

begun and finished it in one morning, between dawn (as we may suppose)

and 8 o'clock--and this is what I believe. If so, it seems a remarkable

feat, but the swiftness with which they dive and swim up with their

cargoes, and the bulk of weeds which these represent makes me think it

possible, though I must confess that all the work which I actually saw

on the morning in question made little perceptible difference in the

size of the heap that was already there on my arrival.

Like an iceberg, the great mass of the nest is beneath the surface of

the water. It seems to be woven amongst the stems of growing weeds or

other aquatic plants, but I have noticed in it (indeed, I have seen

the birds placing and carrying them) water-logged sticks of some size,

one end of which is fixed amongst the mass, whilst the other sinks

down into the mud, and the tangle that may spring from it. Such sticks

must act as so many anchors, and may, perhaps, be the chief means by

which the nest is kept stationary. To judge by the two birds which I

particularly watched, the great crested grebe has the habit of building

several nests, and, besides this, the male makes a small platform of

weeds just off the edge of the bank, and near to the nest. Sometimes he

seems in doubt whether to take his weeds to the nest or the platform,

and in this hesitation, and in the building of more than one nest, we

may, perhaps, see the origin of the latter structure. With regard to

this, and some other points which seemed to me of interest, I may refer

to a paper of mine which has lately appeared in the _Zoologist_.[28] In

this I give a minute account of the nest-building and some other habits

of these birds, as illustrated by a pair which I watched very closely;

and I will here record my conviction that there is more to be learnt by

such watching of any one species, or even any one individual bird, than

in the killing or robbing of thousands.

[28] May 1901.

When I say this, it is not only of the interest that there is in

a creature's ways and habits that I am thinking, but also of the

light that these may, at any moment, throw upon its descent and

affinities--upon all those questions and subjects which are suggested

by the word "evolution" and the names of Darwin and Wallace. To have

a true classificatory system seems to be, now, the grand ideal of the

naturalist, and this, I suppose, must be called a high one, though it

is wonderful how, in some modern works, the soul of it has been taken

out of the body, so that all has become dull and pedantic again, though

a flight of stairs higher up than some fifty years ago. Thus can a

matter seem rich or poor as one or another treats of it. But habits

and instincts are as strongly inherited as structure, so that, as it

appears to me, the study of life is, even from the orthodox scientific

point of view, as important as the study of death. Yet it is death that

most zoologists (as they call themselves) really revel in, and, though

they may not say so, one cannot help feeling that they are a great deal

happier and more comfortable dissecting a body in their study than

studying a life out-of-doors.

Even admitting that both ways of acquiring knowledge are equally

efficacious and legitimate, yet this is very clear, that the

destruction of any species ends both, in regard to it. We can no

more dissect the great auk or the dodo (or blow their eggs) now

than we can observe their habits. Thus it is not only beauty, but

knowledge also--how great and how varied who can say?--that is being

every day drained out of the world, and against this there is, as it

seems to me, an insufficient protest on the part of scientific men

as a body. They care too little about it. When they think of birds

or beasts, it is under glass cases in museums that their mind's

eye sees them, and if there is only a specimen--nay, a bone or a

feather--in one of these, it is to them as though a nation had been

saved. More, if only a specimen, or a bone or feather, can be got for

a museum in which they are interested, for the sake of it such nation

_may_ perish, and of this spirit we have only lately had a salient

example. In their writings, these serenities are accustomed to speak

calmly of the approaching extinction of this or that more or less

lovely or interesting creature--say, for instance, the lyre-bird of

Australia--if, "happily," such and such a museum has been supplied, or

if Professor somebody has ascertained this or that in regard to it;

or professors and the public generally are exhorted to obtain such

supplies or such information "before the end comes."

"Before the end comes!" Every effort should be exhausted, every nerve

strained, to avert such end, which, in nine cases out of ten, could

be averted if the requisite measures were taken. This way of writing,

however, is not calculated to further such efforts, or to hasten the

taking of such measures. Indifference, at least with regard to the

greater evil, is but too clearly indicated, and to this indifference

the life of species after species is sacrificed.

No one, of course, supposes that the opinions or emotions of a

scientific body (and in this I mean to include more than the term

strictly covers) would exercise any influence on money-seeking men

or brainless and heartless women; but they might on that great army

of collectors who, thinking all the while that they are in some way

doing good and helping science, keep sweeping countless thousands of

birds, beasts, eggs, and insects out of existence. Alas for these

amiable basilisks, these busy little man-shaped rinderpests, who kill

so well-meaningly and hate the very breath of life without ever once

knowing it! if they had devoted their whole lives to picking pockets,

or even to being politicians, they would have done, at the end of them,

less harm--far, far less harm--in the world than they are now every day

doing. Every day, through them, some specific life that is, or was,

of more value than all their individual ones put together, is getting

scarcer, or ceasing to be. For, surely, a beautiful butterfly, say,

that, for all time, charms--and raises by charming--some number of

those who see it, does more good on this earth than any single man or

woman, who, "departing," leaves no "footprints on the sands of time."

Homer, for instance, has left his "Iliad" and "Odyssey," and these

have been, and still are, mighty in their effects. But let them once

perish, and Homer will be caught up and overtaken by almost any bird or

butterfly--even a brown one. Or, if Homer will not, assuredly many an

English poet-laureate will be, or has been already (Pye, for instance),

though his volumes in the British Museum are safe as consols. If

there be any truth in this reflection, it should tend to make us a

little less conceited than we are. Yet what is a little in such a

matter?--"Oh, reform it altogether."

For myself, I must confess that I once belonged to this great, poor

army of killers, though, happily, a bad shot, a most _fa_tigable

collector, and a poor, half-hearted bungler, generally. But now that

I have watched birds closely, the killing of them seems to me as

something monstrous and horrible; and, for every one that I have shot,

or even only shot at and missed, I hate myself with an increasing

hatred. I am convinced that this most excellent result might be arrived

at by numbers and numbers of others, if they would only begin to do

the same; for the pleasure that belongs to observation and inference

is, really, far greater than that which attends any kind of skill or

dexterity, even when death and pain add their zest to the latter. Let

anyone who has an eye and a brain (but especially the latter), lay

down the gun and take up the glasses for a week, a day, even for an

hour, if he is lucky, and he will never wish to change back again. He

will soon come to regard the killing of birds as not only brutal, but

dreadfully silly, and his gun and cartridges, once so dear, will be to

him, hereafter, as the toys of childhood are to the grown man.

Nor will the good effect stop here. Birds are but a part of the life

on this our earth, and the hatred of destruction, once kindled by

them, will, like the ripples made by a stone flung into the water,

extend outwards through the whole animal and vegetable kingdom till it

include, at last, man himself--yes, even the Chinese. Unfortunately,

long before anything of this kind is likely to happen, all birds,

except poultry, and, perhaps, a lingering sparrow or two, will have

been destroyed. This seems a cheerless prospect, but, as usual (to

write like an optimist), it has its brighter side. Women will then

be no longer able to wear hats, to adorn which the most beautiful of

earth's creatures have been ruthlessly slaughtered, and, therefore,

faith in them will begin once more to revive. Faith in woman, we know,

is a very important thing. A nation that has once lost it must either

get it again, or go rapidly downhill. How much better, therefore, to

get it again!

I had meant, in this last chapter, besides touching a little more

fully on some points to which I have here and there referred, to say

something about the heron, nightjar, cuckoo, barn-owl, wagtail, and a

few other birds; but I have managed so clumsily that I now find myself

at the furthest possible limit of space, without having left myself

room either for the one or the other. With regard to the nightjar,

I have kept an observational diary on the nesting habits of a pair

of these birds, which was published in the _Zoologist_ for, I think,

September 1899. From this I had intended to quote, as in the case of

the great plover, but it is too late to begin now. All these birds,

therefore, must wait a little, but I will not forget them should I ever

write another book of this kind.
