Educated birds though, like educated dogs, horses, cats, mice, men, and everything else, are very different beings from the uneducated. Cultivation is a key that unlocks all sorts of miracles. Cats are cultivated tigers; and the richest grains that ripen in the fields of men, and the loveliest flowers that blow, are only educated weeds. Even the flea may be taught to exchange leaping for walking, to draw a tiny wagon, to ride on the seat, to fire a toy cannon, and do many other feats.
There is one family of birds in which the superior size, gorgeousness, and vivacity, usual to the males, are found in the other sex, the females being the larger and more brightly coloured—the Phalarope family. Indeed, the members of this small family not only reverse the usual arrangement of the sexual characters of birds, but completely upset many of the most cherished traditions of the avian household. The female does the wooing, and takes the lead in selecting the nest site. And while she lays the eggs, the privilege of incubation she hands over magnanimously to her dull-coloured mate.
Birds have a keen observation and a good deal of that invaluable faculty known as common-sense. It is wonderful how quickly they learn to avoid telegraph-wires when these invisible but deadly gossamers are first stretched across a country, and how unerringly they keep at safe distances when hunted with firearms. An experienced crow can tell a cane from a gun-barrel almost as far as he can see it.
Nearly all birds build nests of some kind in which to cradle their eggs and young. The cow-bird and cuckoo (European), however, are exceptions. These birds have the rather human practice of turning their cares and labours over to somebody else. They are loafers and parasites. They lay their eggs secretly in the nests of other birds, where their eggs are hatched and their young cared for by an alien mother. I have seen a mother song-sparrow hustling about among the shrubs and grasses for an hour at a time almost, gathering food for a young cow-bird nearly twice as big as she was, while her foundling sat phlegmatically at the foot of a tree chirping and fluttering its wings, and acting as a thankless and apparently bottomless receptacle for the morsel after morsel laboriously harvested for it by its tireless little foster-mother. Sand-martins and kingfishers burrow in the earth and rear their broods in subterranean cradles; gulls and gamebirds build on the ground; the flamingoes and barn-swallows build mud nests; the woodpeckers mine holes in trees; doves and eagles make platforms of sticks; the tailor-bird bastes living leaves together; the social weavers construct great straw roofs covering the top of a tree, and build their nests on the limbs beneath; most singing birds build daintily-lined baskets, and swing them in trees and bushes.
It is often said that all the birds of a species build their nests in precisely the same way, and that, while men change and improve their dwelling-places from generation to generation, birds build their abodes in the same old way, just as their ancestors built theirs centuries and centuries ago. This is a favourite thought with the fogies, with those who change not in their thinking from the ways hacked out for them centuries and centuries ago. Birds are like men. Some of them—some races and some individuals—are much more given to initiative than others. There is as wide a difference between the hang-bird and the auk in the construction of their domiciles as between the millionaire and the savage. And the hang-bird has come by her home-making art through centuries of improvement, just as the millionaire has arrived at his. It is believed by ornithologists that the first nests of birds were the niches of rocks or simple hollows scooped in the sand and soil, such as are still seen among the more primitive bird races, and that from these aboriginal beginnings have come, through ages of evolution, the elaborate creations of the cotton-bird, weaver-bird, tailorbird, oven-bird, the baya-sparrow, the finches, and the orioles. The savage who lives unmolested generation after generation in the same land and country builds his simple hut in just the same way as his ancestors built theirs, and thinks the same things his ancestors thought a thousand years before him. Sir Samuel Baker, in a paper on ‘The Races of the Nile Basin,’ points out that each tribe of men in eastern Africa, like each species of bird, has its own peculiar style of hut, and that the huts of the various tribes are as constant in their types as are the nests of birds. The same thing is true of their headdresses as of their huts; and this fixed character exists also in their languages, customs, and religions. It is only some races of men that are given to growth and fluidity, and only some men of these special races.
Right in our own country, among the remote mountain recesses of Appalachia, surrounded on all sides by the most wonderful development, material and intellectual, the world has ever seen, lives a race of rude mountain folk almost as aboriginal in their ways and views of life, and as unaffected by civilisation, as if they were in the heart of Africa. They live huddled together in one-room log-cabins without windows or floors, eat bacon and cornmeal, carry on almost constant wars, and execute the deputies of civilisation who happen to stray into their illicit dominions, just as they have done from the time these mountain silences were first broken by them 150 or 200 years ago.
Birds, as a rule, use a great deal of care and thought in the location of their nests. After they have selected a certain grove or field as the one best suited to their purposes, or as the one around which cluster the happiest memories, it usually requires several days of flying and peeping about, of spying and exploration, before the exact spot for the precious domicile is finally settled upon. It is a delicate matter for many birds, for security from sun, storm, and enemies must all be taken into account. Old birds, as has been frequently observed, build better nests and select more clever locations for their nests than the young and inexperienced. The nest-building habits of many birds are known to have changed during the past few hundred years. The American house-swallow did most certainly not build under the eaves of human houses 300 years ago, nor did the hair-bird in her nest with horsehair as she invariably does now. The fact that wrens, swifts, and martins now build almost altogether in boxes and chimneys shows that birds are able and willing to adapt themselves to new conditions. The chimney-swift and purple martin, it is said, still cling to their aboriginal custom of rearing their young in hollow trees in the unsettled parts of America. The indomitable house-sparrow builds its nest almost anywhere, from knot-holes and tin cans to electric-light globes and tree-tops. Its original dwelling was probably an arboreal affair, like that of other sparrows, and different nesting-places have been adopted as a result of its association with man. Not only in its architecture, but in several other ways, this bird has departed from the traditions of its tribe. The Fringillidae (the sparrow family of birds) are seed-eaters, both in structure and practice. But the house-sparrow, since it left the fields and groves to become a gamin on human streets, has learned to eat almost anything, and one thing, too, about as cheerfully as another. The varied habits of this bird are probably due to its natural elasticity in the first place, supplemented by the unsettling influences of its rather kaleidoscopic experiences during the past few hundred years.
The fear of birds for man is an acquired trait due to ages of persecution. If man would treat birds kindly, they would act toward him as they do toward any other friendly animal. When unfrequented islands are first visited by man, the birds are found to be perfectly fearless of him, flying about him, feeding from his hand, and manifesting no more timidity than if he were a big-hearted bird himself. Darwin states that, when he stopped at the Galapagos Islands on his famous trip around the world in the Beagle, he found the birds there so tame that he could push them from the branches of the trees with his gun-barrel. Professor Cutting, of the State University of Iowa, in an article in the Popular Science Monthly for August, 1903, tells of the almost absolute fearlessness of the birds on the island of Laysan, an isolated atoll in the Pacific west of the Hawaian Islands, which he visited during that summer. The island swarms with bird life—petrels, albatrosses, and tropical birds of various kinds—and these birds betray no more fear in the presence of man than if he were a cow. The albatrosses were so numerous and so indifferent to the presence of man that it was necessary to shove them aside with one’s foot to keep from stepping on them when one went for a walk along the sand-stretches of the shore. Professor Cutting took photographs of birds which literally posed for him in all sorts of positions, and half-savage jackies amused themselves by going about and pulling the pretty tail feathers from the tropical birds as they sat on their nests. I have known of two cases where persons, by going to the same place day after day with food and kindness, have in the course of a few weeks taught robins, sparrows, and other birds, to lose all fear of them, so much so as to sit on their shoulders and arms and eat out of their hands. This is the spirit all birds would show all the time toward their featherless lords if these featherless ones would only treat them with half the consideration they merit.
The love of a bird for the treasures of her nest is one of the most beautiful things of this world. Mother-like, the parent bird will do anything almost for the sake of her little ones. Who has not seen the kildeer strive with all the tact of her clever little soul to allure some big giant of a human being, who has wandered into her neighbourhood, away from her nest of precious young? Many a time as a boy on the farm I have followed one of these birds limping and tumbling and fluttering along on the ground a few feet ahead of me, utterly disabled, as I supposed, but always managing to keep just a little beyond the reach of my eager hands. And when the artful mother has led me far from the sacred spot where lay all there was in this world to her, how triumphantly she has lifted herself on her unharmed wings and, to my utter astonishment, sailed away. The partridge and the mourning-dove are, if possible, even more artful in their acting than the kildeer. After I became a large boy and had been told the meaning of these exhibitions by parent birds, I often followed the mourning-dove, thinking the bird must be really wounded after all, so perfectly did it pretend. But the cunning of the kildeer is not confined to luring one away from the nest. If by some accident one finds her nest (and the nest is so cleverly concealed that, if it is discovered at all, it will be by pure accident), the resourceful mother is ready with other expedients to outwit you. She watches you all the time from the proper distance, and knows by your conduct the moment you have found her nest. And before you have even had time to admire the skill displayed by the mother in blending so perfectly her abode with its surroundings, a single peculiar note from her has caused the whole nestful of cuddling young ones to dart out of their cradle and disappear among the surrounding clods as if by magic. No amount of searching can find one of them. They have vanished as effectually as if they had evaporated. And it is enough to touch the heart of the most indifferent to see the anxious mother bird, as I have seen her from the cranny of a neighbouring rock-pile, come back to her nest and call her scattered children together again after they have once dispersed at her command. Circling around the nest two or three times to assure herself that no one is nigh, she alights and begins a low clucking sound like that of a hen calling her brood. The little ones come out of their hiding-places one after another as mysteriously as they vanished. You can’t see for the life of you where they come from. They seem to just emanate. And if one of them fails to come at her call—for the devoted mother knows very well just how many she has—she extends her search farther out from her nest, looking all around and keeping up that peculiar little cluck, until the half-scared-to-death little slyboots finally comes creeping out from his improvised snuggery somewhere. If a kildeer’s nest has once been found, and the mother feels that it is in danger of future visits, she will move her family at night to some other locality, and it is practically impossible ever to find it again. The family relations of the ring-dotterels are said to be ‘so charming and touching that even hunters recoil from shooting a female surrounded by her young ones.’
Human beings, true to their instinct never to call into action their ability to think if they can employ their faculty for nonsense instead, call this love of the mother bird ‘machinery.’ But there are some of us (and our numbers are increasing) who are disposed to put off the adoption of this conclusion until we go mad. The bird builds her nest, weaving it of the rarest fibres. She hides it in the copse or prudently hangs it far out on some inaccessible bough. She lays her beautiful eggs, and hatches them with the warmth and life of her own breast. She tends her young, bringing them food and drink, and watching over them with a tender and tireless vigilance. She protects them in storm with her own little body, worries about them when danger lurks, and dreams of them, no doubt, as she rocks and sleeps under the silent stars. She sings to them in the overflow of her gladness and hope, and risks her very existence to shield them from harm. She teaches them to fly, to find their food, and to detect their enemies. She is true to her mate, and her mate is true and kind to her. As the days of summer shorten, and the cool, long nights warn of approaching autumn, she leads her children away from the old place, she and her faithful mate, out into the wide old world. And I say there is love in the heart of that mother as truly as in the heart of woman, and there are joy and genuineness and sorrow and fidelity in that sylvan home more sacred than may sometimes bloom in the cold mansions of men.
