THE NEST. ARCHITECTURE OF BIRDS.

Previous

I am writing opposite a graceful collection of nests of French birds, made for me by a friend. I am able thus to appreciate, to verify the descriptions of authors, to improve them, perhaps, if the very limited resources of style can give any just idea of a wholly special art, less analogous to ours than one would be tempted to believe at the first glance. Nothing in this branch of study can supply the place of actual sight of the objects. You must see and touch; you will then perceive that all comparison is false and inaccurate. These things belong to a world apart. Shall we say above, or below the works of man? Neither the one nor the other; but essentially different, and whose supposed similarities (or relations) are only external.

Let us recollect, at the outset, that this charming object, so much more delicate than words can describe, owes everything to art, to skill, to calculation. The materials are generally of the rudest, and not always those which the artist would have preferred. The instruments are very defective. The bird has neither the squirrel's hand nor the beaver's tooth. Having only his bill and his foot (which by no means serves the purpose of a hand), it seems that the nest should be to him an insoluble problem. The specimens now before my eyes are for the most part composed of a tissue or covering of mosses, small flexible branches, or long vegetable filaments; but it is less a weaving than a condensation; a felting of materials, blended, beaten, and welded together with much exertion and perseverance; an act of great labour and energetic operation, for which the bill and the claw would be insufficient. The tool really used is the bird's own body—his breast—with which he presses and kneads the materials until he has rendered them completely pliable, has thoroughly mixed them, and subdued them to the general work.

And within, too, the implement which determines the circular form of the nest is no other than the bird's body. It is by constantly turning himself about, and ramming the wall on every side, that he succeeds in shaping the circle.

Thus, then, his house is his very person, his form, and his immediate effort—I would say, his suffering. The result is only obtained by a constantly repeated pressure of his breast. There is not one of these blades of grass but which, to take and retain the form of a curve, has been a thousand and a thousand times pressed against his bosom, his heart, certainly with much disturbance of the respiration, perhaps with much palpitation.

It is quite otherwise with the habitat of the quadruped. He comes into the world clothed; what need has he of a nest? Thus, then, those animals which build or burrow labour for themselves rather than for their young. A skilful miner is the mountain rat, in his oblique tunnel, which saves him from the winter gale. The squirrel, with hand adroit, raises the pretty turret which defends him from the rain. The great engineer of the lakes, the beaver, foreseeing the gathering of the waters, builds up several stages to which he may ascend at pleasure; but all this is done for the individual. The bird builds for her family. Carelessly did she live in her bright leafy bower, exposed to every enemy; but the moment she was no longer alone, the hoped for and anticipated maternity made her an artist. The nest is a creation of love.

Thus, the work is imprinted with a force of extraordinary will, of a passion singularly persevering. You see in it especially this fact, that it is not, like our works, prepared from a model, which settles the plan, conducts and regulates the labour. Here the conception is so thoroughly in the artist, the idea so clearly defined, that, without frame or carcase, without preliminary support, the aerial ship is built up piece by piece, and not a hitch disturbs the ensemble. All adjusts itself exactly, symmetrically, in perfect harmony; a thing infinitely difficult in such a deficiency of tools, and in this rude effort of concentration and kneading by the mere pressure of the breast. The mother does not trust to the male bird for all this; but she employs him as her purveyor. He goes in quest of the materials—grasses, mosses, roots, or branches. But when the ship is built, when the interior has to be arranged—the couch, the household furniture—the matter becomes more difficult. Care must be taken that the former be fit to receive an egg peculiarly sensitive to cold, every chilled point of which means for the little one a dead limb. That little one will be born naked. Its stomach, closely folded to the mother's, will not fear the cold; but the back, still bare, will only be warmed by the bed; the mother's precaution and anxiety are, therefore, not easily satisfied. The husband brings her some horse-hair, but it is too hard; it will only serve as an under-stratum, a sort of elastic mattress. He brings hemp, but that is too cold; only the silk or silky fibre of certain plants, wool or cotton, are admissible; or better still, her own feathers, her own down, which she plucks away, and deposits under the nursling. It is interesting to watch the male bird's skilful and furtive search for materials; he is apprehensive lest you should learn, by watching him with your eyes, the track to his nest. Frequently, if you look at him, he will take a different road, to deceive you. A hundred ingenious little thefts respond to the mother's desire. He will follow the sheep to collect a little wool. From the poultry-yard he will gather the dropped feathers of the mother hen. If the farmer's wife quit for a moment her seat in the porch, and leave behind her distaff or ball of thread, he will spy his opportunity, and go off the richer for a thread or two.

Collections of nests are very recent, not numerous, and, as yet, not rich. In that of Rouen, however, which is remarkable for its arrangement; in that of Paris, where many very curious specimens may be examined; you can distinguish already the different industries which create this master-piece of the nest. What is the chronology, the gradual growth of it? Not from one art to another (not from masonry to weaving, for example); but in each separate art, the birds which abandon themselves to it are more or less successful, according to the intelligence of the species, the abundance of material, or the exigency of climate.

Among the burrowing birds, the booby, and the penguin, whose young, as soon as born, spring into the sea, content themselves with hollowing out a rude hole. But the bee-eater, the sea-swallow, which must educate their young, excavate under the ground a dwelling which is admirably proportioned, and not without some geometrical design. They furnish it, moreover, and strew it with soft yielding substances on which the fledgling will be less sensitive to the hardness or freshness of the humid soil.

Among the building-birds, the flamingo, which raises a pyramid of mud to isolate her eggs from the inundated earth, and, while standing erect, hatches them under her long legs, is contented with a rude, rough work. It is, moreover, a stratagem. The true mason is the swallow, which suspends her house to ours.

The marvel of its kind is, perhaps, the wonderful carpentry which the thrush executes. The nest, very much exposed under the moist shelter of the vines, is made externally of moss, and amid the surrounding verdure escapes the eye; but look within: it is an admirable cupola, neat, polished, shining, and not inferior to glass. You may see yourself in it as in a mirror.

The rustic art, appropriate to the forests, of timber-work, joining, wood-carving, is attempted on the lowest scale by the toucan, whose bill, though enormous, is weak and thin: he attacks only worm-eaten trees. The woodpecker, better armed, as we have seen, accomplishes more: he is a true carpenter; until love inspires him, and he becomes a sculptor.

Infinite in varieties and species is the guild of basket-makers and weavers. To note the starting-point, the advance, and the climax of an industry so varied, would be a prolonged labour.

The shore birds plait, to begin with, but very unskilfully. Why should they do better? So warmly clothed by nature with an unctuous and almost impermeable coat of plumage, they have little need to allow for the elements. Their great art is the chase; always lank, and insufficiently fed, the piscivora are controlled by the wants of a craving stomach.

The very elementary weaving of the herons and storks is already outstripped, though to no great extent, by the basket-makers of the woods, the jay, the mocking-bird, the bullfinch. Their more numerous brood impose on them more arduous toil. They lay down rude enough foundations, but thereupon plant a basket of more or less elegant design, a web of roots and dry twigs strongly woven together. The cistole delicately interlaces three reeds or canes, whose leaves, mingled with the web, form a safe and mobile base, undulating as the bird rocks. The tomtit suspends her purse-like cradle to a bough, and trusts to the wind to nurse her progeny.

The canary, the goldfinch, the chaffinch, are skilful felters. The latter, restless and suspicious, attaches to the finished nest, with much skill and address, a quantity of white lichens, so that the spotted appearance of the whole completely misleads the seeker, and induces him to take this charming and cunningly disguised nest for an accident of vegetation, a fortuitous and natural object.

Glueing and felting play an important part in the work of the weavers. It would be a mistake to separate these arts too widely. The humming-bird consolidates its little house with the gum of trees. Most birds employ saliva. Some—a strange thing, and a subtle invention of love!—here make use of processes for which their organs are least adapted. An American starling contrives to sew the leaves with its bill, and does so very adroitly.

A few skilful weavers, not satisfied with the bill, bring into play their feet. The chain prepared, they fix it with their feet, while the beak inserts the weft. They become genuine weavers.

In fine, skill never fails them. It is very astonishing, but implements are wanting. They are strangely ill-adapted for the work. Most insects, in comparison, are wonderfully furnished with arms and utensils. But these are true workmen, are born workmen. The bird is so but for a time, through the inspiration of love.
