BIRD INTIMACIES

When, as sometimes happens, I feel an inclination to seek out new lands in my own country, or in other countries, to see what Nature is doing there, and what guise she wears, something prompts me to pause, and after a while to say to myself: "Look a little closer into the nature right at your own door; do a little intensive observation at home, and see what that yields you. The enticement of the far-away is mostly in your imagination; let your eyes and your imagination play once more on the old familiar birds and objects."

One season in my walks to the woods I was on the lookout for a natural bracket among the tree-branches, to be used in supporting a book-shelf. I did not find it; but one day in a shad-blow tree, within a few feet from the corner of my own house, I found what I was searching for, perfect in every particular – the right angle and the supporting brace, or hypothenuse. It gave me a hint I have not forgotten.

I find that one has only to overcome a little of his obtuseness and indifference and look a little more closely upon the play of wild life about him to realize how much interesting natural history is being enacted every day before his very eyes – in his own garden and dooryard and apple-orchard and vineyard. If one's mind were only alert and sensitive enough to take it all in! Whether one rides or walks or sits under the trees, or loiters about the fields or woods, the play of wild life is going on about him, and, if he happens to be blessed with the seeing eye and the hearing ear, is available for his instruction and entertainment. On every farm in the land a volume of live natural history goes to waste every year because there is no historian to note the happenings.

The drama of wild life goes on more or less behind screens – a screen of leaves or of grass, or of vines, or of tree-trunks, and only the alert and sympathetic eye penetrates it. The keenest of us see only a mere fraction of it. If one saw one tenth of the significant happenings that take place on his few acres of orchard, lawn, and vineyard in the course of the season, or even of a single week, what a harvest he would have! The drama of wild life is played rapidly; the actors are on and off the stage before we fairly know it, and the play shifts to other stages.

I wonder how many of the scores of persons passing along the road between my place and the railway station one early May day became aware that a rare bird incident was being enacted in the trees over their heads. It was the annual sängerfest of the goldfinches – one of the prettiest episodes in the lives of any of our birds, a real musical reunion of the goldfinch tribe, apparently a whole township, many hundreds of them, filling scores of the tree-tops along the road and in the groves with a fine, sibilant chorus which the ear refers vaguely to the surrounding tree-tops, but which the eye fails adequately to account for. It comes from everywhere, but from nowhere in particular. The birds sit singly here and there amid the branches, and it is difficult to identify the singers. It is a minor strain, but multitudinous, and fills all the air. The males are just donning their golden uniforms, as if to celebrate the blooming of the dandelions, which, with the elm-trees, afford them their earliest food-supply. While they are singing they are busy cutting out the green germs of the elm flakes, and going down to the ground and tearing open the closed dandelion-heads that have shut up to ripen their seeds, preparatory to their second and ethereal flowering when they become spheres of fragile silver down.

Whether this annual reunion of the goldfinches should be called a dandelion festival, or a new-coat festival, or whether it is to bring the sexes together preliminary to the mating-season, I am at a loss to decide. It usually lasts a week or more, and continues on wet days as well as on fair. It all has a decidedly festive air, like the fête-days of humans. I know of nothing like it among other birds. It is the manifestation of something different from the flocking instinct; it is the social and holiday instinct, bringing the birds together for a brief season, as if in celebration of some special event or purpose. I have observed it in my vicinity every spring for many years, usually in April or early May, and it is the prettiest and most significant bird episode, involving a whole species, known to me.

The goldfinch has many pretty ways. He is one of our most amiable birds. So far as my knowledge goes, he is not capable of one harsh note. His tones are all either joyous or plaintive. In his spring reunions they are joyous. In the peculiar flight-song in which he indulges in the mating season, beating the air vertically with his round, open wings, his tones are fairly ecstatic. His call to his mate when she is brooding, and when he circles about her in that long, billowy flight, the crests of his airy waves being thirty or forty feet apart, calling, "Perchic-o-pee, perchic-o-pee," as if he were saying, "For love of thee, for love of thee," and she calling back, "Yes, dearie; yes, dearie" – his tones at such times express contentment and reassurance.

When any of his natural enemies appear – a hawk, a cat, a jay – his tones are plaintive and appealing. "Pit-y, pit-y!" he cries in sorrow and not in anger.

When with his mate he leads their brood about the August thistles, the young call in a similar tone. When in July the nesting has begun, the female talks the prettiest "baby talk" to her mate as he feeds her. The nest-building rarely begins till thistledown can be had – so literally are all the ways of this darling bird ways of softness and gentleness. The nest is a thick, soft, warm structure, securely fastened in the fork of a maple or an apple-tree.

None of our familiar birds endear themselves to us more than does the bluebird. The first bluebird in the spring is as welcome as the blue sky itself. The season seems softened and tempered as soon as we hear his note and see his warm breast and azure wing. His gentle manners, his soft, appealing voice, not less than his pleasing hues, seem born of the bright and genial skies. He is the spirit of the April days incarnated in a bird. He has the quality of winsomeness, like the violet and the speedwell among the flowers. Not strictly a songster, yet his every note and call is from out the soul of harmony. The bluebird is evidently an offshoot from the thrush family, and without the thrush's gift of song; still his voice affords us much of the same pleasure.

How readily the bluebirds become our friends and neighbors when we offer them suitable nesting-retreats! Bring them something from nature, something with the bark on – a section of a dry beech or maple limb in which the downy woodpecker has excavated his chamber and passed the winter or reared his brood; fasten it in early spring upon the corner of your porch, or on the trunk of a near-by tree, and see what interesting neighbors you will soon have. One summer I brought home from one of my walks to the woods a section, two or three feet long, of a large yellow birch limb which contained such a cavity as I speak of, and I wired it to one of the posts of the rustic porch at Woodchuck Lodge. The next season a pair of bluebirds reared two broods in it. The incubation of the eggs for the second brood was well under way when I appeared upon the scene in early July. My sudden presence so near their treasures, and my lingering there with books and newspapers, disturbed the birds a good deal. The first afternoon the mother bird did not enter the cavity for hours. I shall always remember the pretty and earnest manner in which the male tried to reassure her and persuade her that the danger was not so imminent as it appeared to be, probably encouraging a confidence in his mate which he did not himself share. The mother bird would alight at the entrance to the chamber, but, with her eye fixed upon the man with the newspaper, feared to enter. The male, perched upon the telegraph wire fifty feet away, would raise his wings and put all the love and assurance in his voice he was capable of, apparently trying to dispel her fears. He would warble and warble, and make those pretty wing gestures over and over, saying so plainly: "It is all right, my dear, the man is harmless – absorbed there in his newspaper. Go in, go in, and keep warm our precious eggs!" How long she hesitated! But as night grew near she grew more and more anxious, and he more and more eloquent. Finally she alighted upon the edge of the overhanging roof and peered down hesitatingly. Her mate applauded and encouraged till finally she made the plunge and entered the hole, but instantly came out again; her heart failed her for a moment; but she soon returned and remained inside. Then her mate flew away toward the orchard, uttering a cheery note which doubtless she understood.

The birds soon became used to my presence and their household matters progressed satisfactorily. Both birds took a hand in feeding the young, which grew rapidly. When they were nearly ready to leave the nest, a cruel fate befell them: I slept upon the porch, and one night I was awakened by the cry of young bluebirds, and the sound of feet like those of a squirrel on the roof over me. Then I heard the cry of a young bird proceed from the butternut-tree across the road opposite the house. I said to myself, "A squirrel or an owl is after my birds." The cry coming so quickly from the butternut-tree made me suspect an owl, and that the bird whose cry I heard was in his talons. I was out of my cot and up to the nest in a moment, but the tragedy was over; the birds were all gone, and the night was silent. In the morning I found that a piece of the brittle birch limb had been torn away, enlarging the entrance to the cavity so that the murderous talons of the owl could reach in and seize the young birds. I had been aroused in time to hear the marauder on the roof with one, and then hear its cry as he carried it to the tree. In the grass in front I found one of the young, unable to fly, but apparently unhurt. I put it back in the nest, but it would not stay. The spell of the nest was broken, and the young bird took to the grass again. The parent birds were on hand, much excited, and, when I tried to return the surviving bird to the nest, the male came at me fiercely, apparently charging the whole catastrophe to me.

We had strong proof the previous season that an owl, probably the screech owl, prowled about the house at night. A statuette of myself in clay which a sculptor was modeling was left out one night on the porch, and in the morning its head was unusually bowed. The prints of a bird's talons upon the top told what had happened. In the bronze reproduction of that statuette the head has more of a droop than the artist at first planned to give it.

The next season the bluebirds occupied the cavity in the birch limb again, but before my arrival in July the owls had again cleaned them out. In so doing they had ripped the cavity open nearly to the bottom. For all that, early the following May bluebirds were occupying the cavity again. It held three eggs when I arrived. I looked over the situation and resolved to try to head off the owl this time, even at the risk of driving the bluebirds away. I took a strip of tin several inches wide and covered the slit with it and wired it fast. Then I obtained a broad strip of dry birch-bark, wrapped it about the limb over the tin, and wired it fast, leaving the entrance to the nest in its original form. I knew the owl could not slit the tin; the birch-bark would hide it and preserve in a measure the natural appearance of the branch. When the bluebirds saw what had happened to their abode, they were a good deal distressed; they could no longer see their eggs through the slit which the owl had made, and they refused to enter the cavity. They hung about all day, uttering despondent notes, approaching the nest at times, but hesitating even to alight upon the roof above it. Occasionally the female would fly away toward the distant woods or hills uttering that plaintive, homesick note which seemed to mean farewell. The male would follow her, calling in a more cheery and encouraging tone. Once the couple were gone three or four hours, and I concluded they had really deserted the place. But just before sundown they were back again, and the female alighted at the entrance to the nest and looked in. The male called to her cheerily; still she would not enter, but joined him on the telephone wire, where the two seemed to hold a little discussion. Presently the mother bird flew to the nest again, then to the roof above it, then back to the nest, and entered it till only her tail showed, then flew back to the wire beside her mate. She was evidently making up her mind that the case was not hopeless. After a little more maneuvering, and amid the happy, reassuring calls of her mate, she entered the nest cavity and remained, and I was as well pleased as was her mate.

No owls disturbed them this time, and the brood of young birds was brought off in due season. In July a second brood of four was successfully reared and sent forth on their career.

The oriole nests in many kinds of trees – oaks, maples, apple-trees, elms – but her favorite is the elm. She chooses the end of one of the long drooping branches where a group of small swaying twigs affords her suitable support. It is the most unlikely place imaginable for any but a pendent nest, woven to half a dozen or more slender, vertical twigs, and swaying freely in the wind. Few nests are so secure, so hidden, and so completely sheltered from the rains by the drooping leaves above and around it. It is rarely discoverable except from directly beneath it. I think a well-built oriole's nest would sustain a weight of eight or ten pounds before it would be torn from its moorings. They are also very partial to the ends of branches that swing low over the highway. One May I saw two female orioles building their nests twenty or twenty-five feet above our State Road, where automobiles and other vehicles passed nearly every minute all the day. An oriole's nest in a remote field far from highways and dwellings is a rare occurrence.

Birds of different species differ as widely in skill in nest-building as they do in song. From the rude platform of dry twigs and other coarse material of the cuckoo, to the pendent, closely woven pouch of the oriole, the difference in the degree of skill displayed is analogous to the difference between the simple lisp of the cedar-bird, or the little tin whistle of the "chippie," and the golden notes of the wood thrush, or the hilarious song of the bobolink.

Real castles in the air are the nests of the orioles; no other nests are better hidden or apparently more safe from the depredations of crows and squirrels. To start the oriole's nest successfully is quite an engineering feat. The birds inspect the branches many times before they make a decision. When they have decided on the site, the mother bird brings her first string or vegetable fiber and attaches it to a twig by winding it around and around many times, leaving one or both ends hanging free. I have nests where these foundation strings are wound around a twig a dozen times. In her blind windings and tuckings and loopings the bird occasionally ties a substantial knot, but it is never the result of a deliberate purpose as some observers contend, but purely a matter of chance. When she uses only wild vegetable fibers, she fastens it to the twig by a hopeless kind of tangle. It is about the craziest kind of knitting imaginable. After the builder has fastened many lines to opposite twigs, their ends hanging free, she proceeds to span the little gulf by weaving them together. She stands with her claws clasped one to each side, and uses her beak industriously, looping up and fastening the loose ends. I have stood in the road under the nest looking straight up till my head swam, trying to make out just how she did it, but all I could see was the bird standing astride the chasm she was trying to bridge, and busy with the hanging strings. Slowly the maze of loose threads takes a sacklike form, the bottom of the nest thickens, till some morning you see the movement of the bird inside it; her beak comes through the sides from within, like a needle or an awl, seizes a loose hair or thread, and jerks it back through the wall and tightens it. It is a regular stitching or quilting process. The course of any particular thread or fiber is as irregular and haphazard as if it were the work of the wind or the waves. There is plan, but no conscious method of procedure. In fact, a bird's nest is a growth. It is not something builded as we build, in which judgment, design, forethought enter; it is the result of the blind groping of instinct which rarely errs, but which does not see the end from the beginning, as reason does. The oriole sometimes overhands the rim of her nest with strings and fibers to make it firm, and to afford a foundation for her to perch upon, but it is like the pathetic work which an untaught blind child might do under similar conditions. The birds use fine, strong strings in their nest-building at their peril. Many a tragedy results from it. I have an oriole's nest sent me from Michigan on the outside of which is a bird's dried foot with a string ingeniously knotted around it. It would be difficult to tie so complicated a knot. The tragedy is easy to read. Another nest sent me from the Mississippi Valley is largely made up of fragments of fish-line with the fish-hooks on them. But there is no sign that the bird came to grief using this dangerous material. Where the lives of the wild creatures impinge upon our lives is always a danger-line to them. They are partakers of our bounty in many ways, but they pay a tax to fate in others.

The orioles in my part of the country always use the same material in the body of their nests – a kind of soft, gray, flaxlike fiber which they apparently get from some species of everlasting flower. Woven together and quilted through with strings and horse-hairs, it makes strong, warm, feltlike walls. In the nest sent me from Michigan the walls are made of something that suggests brown human hair, except that it is too hard and brittle for hair.

Our orchard oriole also makes a pendent nest, but not so deep and pocketlike as that of the Baltimore oriole, and showing no such elaborate use of strings and hairs. It is made entirely of some sort of dried grass, very elaborately woven together.

Bullock's oriole of California weaves its nest entirely of the long, strong threads which it draws out of the palm-leaves. The only one I have seen was suspended from the under side of one of those leaves.

I think the prize nest of the woods, if we except the nest of the hummingbird, is that of the wood pewee. It is as smooth and compact and symmetrical as if turned in a lathe out of some soft, feltlike substance. Of course, the ph[oe]be's artistic masonry under the shelving rocks, covered with moss and lined with feathers, or with the finest dry grass and bark fibers, sheltered from the storms and beyond the reach of four-footed prowlers, is almost ideal. It certainly is a happy thought.

The least flycatcher, the kingbird, the cedar-bird, the goldfinch, the indigo-bird, are all fine nest-builders, each with a style of its own.

About the most insecure nest in our trees is that of the little social sparrow, or "chippie." When the sudden summer storms come, making the tree-tops writhe as if in agony, I think of this frail nest amid the tossing branches. Pass through the grove or orchard after the tempest is over, and you are pretty sure to find several wrecked nests upon the ground. "Chippie" has never learned the art of nest-building in trees. She is a poor architect. She should have kept to the ground or to the low bushes. The true tree nest-builders weave their nests fast to the branches, but "Chippie" does not; she simply arranges her material loosely between them, where the nest is supported, but not secured. She seems pathetically ignorant of the fact that there are such things as wind and storm. Hence her frail structure is more frequently dislodged from the trees than that of any other bird.

Recently, after a day of violent northwest wind, I found a wrecked robin's nest and eggs upon the lawn under a maple – not a frequent spectacle. The robin's firm masonry is usually proof against wind and rain, but in this case the nest was composed almost entirely of dry grass; there was hardly a trace of mud in it, hence it was flexible and yielding, and had no grip of the branches. It was evidently the second nest of the pair this season, and the second nest in summer of any species of bird is frailer and more of a makeshift than the first nest in spring. Comparatively few of our birds attempt to bring off a second brood unless the first attempt has been defeated, but the robin is sure to bring off two, and may bring off three. But the robin is a hustler, probably the most enterprising of all our birds. I recall a mother robin that, in late June, repaired a nest in a climbing rosebush which her first brood had vacated only a week before. A brood of wood thrushes which left their nest about the same time was still being fed by their parents about the place.

The song sparrow, the social sparrow, the ph[oe]be, the bluebird, all build a second nest. The first brood of the bluebird will be looked after by the father in some near-by grove or orchard, while the mother starts a new family in the old nest. If all goes well with them, those two bluebird families will unite and keep together in a loose flock till they migrate in the fall.

So many of our birds nest about our houses and lawns and gardens and along our highways, that at first sight it seems as if they must be drawn there by a sense of greater security for their eggs and young. The robin has become almost a domestic institution. It is rarely that one finds a robin's nest very far from a human habitation. One spring there were four robins' nests on my house and outbuildings – in the vines, on window-sills, or other coigns of vantage. There were at the same time at least fifteen robins' nests on my lot of sixteen acres, and I am quite certain that I have not seen all there were. They were in sheds and apple-trees and spruces and cedars, in the ends of piles of grape-posts, in rosebushes, in the summer-house, and on the porch. We did not expect to get one of the early cherries, and might count ourselves lucky if we got any of the later ones.

A robin has built her nest in my summer-house. She abuses me so when I try to tarry there, after incubation has begun, that I take no comfort and presently withdraw. Until her brood has flown, I am practically a stranger in my open-air rest-house and study.

When the fish crows come egging in the spruces and maples about the house, and I hear the screaming of the robins, I seize my gun and rush out to protect them, but am not always successful, as the mischief is often done before I get within reach; I am not sure but that the robins think – if they think at all – that I am in league with the crows to despoil them. I was not in time to save the eggs of the wood thrush the other morning, when I heard the alarm calls of the birds, but I had the satisfaction of seeing the black marauder go limping over the hill, dropping quills from his wings at nearly every stroke. I am sure he will not come back. The fish crow is one of the most active enemies of our small birds. Of course, he only obeys his instincts in hunting out and devouring their eggs and young, but I fancy I obey something higher than instinct when I protest with powder and shot.

The birds do not mind the approach of the domestic animals, such as the cow, the horse, the sheep, the pig, and they are only a little suspicious of the dog, but the appearance of the cat fills them with sudden alarm. I think that birds that have never before seen a cat join in the hue and cry. What alarms one alarms all within hearing. The orioles are probably the most immune from the depredations of crows and jays and owls of all our birds, and yet they will join in the cry of "Thief, thief!" when a crow appears. (The alarm cry of birds will even arrest the attention of four-footed beasts, and often bring the sportsman's stalking to naught.)

I fancy that Ph[oe]be selects our sheds and bridges and porticoes for her nesting-sites because they are so much more numerous than the overhanging rocks where her forbears built. For the same reason certain of the swallows and the swifts select our barns and chimneys.

If the birds themselves are not afraid to draw near us, why should their instinct lead them to feel that their enemies will be afraid of us? How do they know that a jay or a crow or a red squirrel will be less timid than they are? And why also, if they have such confidence in us, do they raise such a hue and cry when we pass near their nests? The robin in my summer-house knew, if she knew anything, that I had never raised a finger against her. On the contrary, my hoe in the garden had unearthed many a worm and slug for her. Still she sees in me only a possible enemy, and tolerate me with my book or my newspaper near her nest she will not. Another robin has built her nest in a rosebush that has been trained to form an arch over the walk that leads to the kitchen door and only a few yards from it; but whenever we pass and repass she scurries away with loud, angry protests and keeps it up as long as we are in sight, so that we do not feel at all complimented by her settling down so near us. If one's appearance is so alarming, even when he is going to hoe the garden, why did the intolerant bird set up her household gods so near? If I keep away her enemies, why will she not be gracious enough to regard me as her friend? The robin that trusted her brood to the sheltering vines of the woodshed, and lined her nest with the hair of our old gray horse – why should she scream, "Murder!" whenever any of us go to the well a few feet away?

What is the real explanation of the fact that so many of our birds nest so near our dwellings and yet show such unfriendliness when we come near them? Their apparent confidence, on the one hand, contradicts their suspicion on the other. Is it because we have here the workings of a new instinct which has not yet adjusted itself to the workings of the older instinct of solicitude for the safety of the nest and young? My own interpretation is that birds are not drawn near us by any sense of greater security in our vicinity. It is evident from the start that there is an initial fear of us to be overcome. How, then, could the sense of greater safety in our presence arise? Fear and trust do not spring from the same root. How should the robins and thrushes know that their enemies – the jays, the crows, and the like – are more afraid of human beings than they are themselves? Hunted animals pursued by wolves or hounds will at times take refuge in the haunts of men, not because they expect human protection, but because they are desperate, and oblivious to everything save some means of escape. If the hunted deer or fox rushes into an open shed or a barn door, it is because it is desperately hard-pressed, and sees and knows nothing but some object or situation that it may place between itself and its deadly enemy. The great fear obliterates all minor fears.

The key to the behavior of the birds in this respect may be found in the Darwinian theory of natural selection. From the first settlement of the country a few of the common birds, attracted by a more suitable or more abundant food-supply, or other conditions, must inevitably have nested near human dwellings. These birds would thrive better and succeed in bringing off more young than those that nested in more exposed places. Hence, their progeny would soon be in the ascendancy. All animals seem to have associated memory. These birds would naturally return to the scenes and conditions of their youth, and start their nests there. It would not be confidence in men that would draw them; rather would the truth be that the fear of man is inadequate to overcome or annul this home attraction.

The catbird does not come to our vines on the veranda to nest from considerations of safety, but because her line of descent runs through such places. The catbirds and robins and ph[oe]be-birds that were reared far from human habitations doubtless return to such localities to rear their young. The home sense in birds is strong. I have positive proof in a few instances of robins and song sparrows returning successive years to the same neighborhood. It is very certain, I think, that the ph[oe]be-birds that daub our porches with their mud, and in July leave a trail of minute creeping and crawling pests, were not themselves hatched and reared in the pretty, moss-covered structure under the shelving rocks in the woods, or on the hillsides.

How different from the manners of the robins are the manners of a pair of catbirds that have a nest in the honeysuckle against the side of the first-floor sleeping-porch! Nothing seems farther from the nature of the catbird than the hue and cry which the robin at times sets up. The catbird is sly and dislikes publicity. An appealing feline mew is her characteristic note. She never raises her voice like the town-crier, as the robin does, perched in the mean time where all eyes may behold him. The catbird peers and utters her soft protest from her hiding-place in the bushes. This particular pair of catbirds appeared in early May and began slyly to look over the situation in the vines and bushes about the house. All their proceedings were very stealthy; they were like two dark shadows gliding about, avoiding observation – no tree-tops or house-tops for them, but coverts close to the ground. We hoped they would divine safety in the shadow of the cottage, but tried to act as if oblivious of their goings and comings. We saw them now and then stealthily inspecting the tangle of honeysuckle on the east side of the veranda, where a robin last season reared a brood, and the low hedge of barberry-bushes on the south side of the cottage, where a song sparrow had her nest. If they come, which will they take, we wondered. Several times in the early morning I heard the male singing vivaciously and confidently in the thick of the honeysuckle. I guessed that the honeysuckle was the choice of the male, and that his song was a pæan in praise of it, addressed to his mate. But it was nearly a week before his musical argument prevailed and the site was apparently agreed upon.
