Birdwatching

“ If by accident one happens upon a sleeping bird, it suddenly rouses and flies away, making no more sound than a passing butterfly — a curious and uncanny silence that is quite remarkable. When the sun goes down and as the gloaming deepens, the bird's activity increases, and it begins its nightly duties, emitting from time to time, like a sentry on his post or a watchman of the night, the doleful call which has given the bird its common name. ”

“ He liked to watch birds in the high alfalfa under the sycamores, but when it came to standing still where the hot sun beat down through the brush and there was nothing to eat, his interest in ornithology flagged perceptibly. Then he sometimes carried the rôle of grazing horse too far, marching off to a fresh clump of grass out of sight of my nest at the most interesting moment; or when I was intently gazing through my glass at a rare bird, he would sometimes give a sudden kick at a horsefly, bobbing the glass out of range just as I was making out the character of the wing-bars. ”

“ The tread of the tall bird himself no one hears, so carefully does he place his foot on the moist ground, cautiously suspending it for a while at each step of his progress. Now his golden eye glances over the surrounding objects, in surveying which he takes advantage of the full stretch of his graceful neck. Satisfied that no danger is near, he lays his head on his shoulders, allows the feathers of his breast to droop, and patiently awaits the approach of his finned prey. You might imagine what you see to be the statue of a bird, so motionless is it. ”

“ When thus disporting, each within its own charmed circle, the downward rush and bleat of one snipe will often for a long time immediately precede or follow that of another, bleat answering to bleat, till at length the duet is broken and complicated by a third intermingling voice. At last a bird, trampling on etiquette, will flit into the circle of the one you are watching, and the two, excitedly pursuing each other with "chack-wood, chack-wood," or, with the harsh, wild scream and loud swish of pinions, will speed off and vanish together. ”

“ This holds good of a considerable number of species, studied with special reference to their flight, as the robin, the wood-thrush, cedar-bird, cat-bird, pewee, and indigo-bird.
It is doubtful if young birds, while yet in their nests, are conscious of the use to be made of their wings. After long-continued experimenting, I find they make no use of them, in endeavoring to escape, but trust to their legs entirely, if removed from the nest, or defend themselves by pecking at the intruder. ”

“ Well, as you are proceeding, full of anxiety, and gazing in astonishment at the multitudes of feathered travellers, all of a sudden a larger bird attracts your eye. It sweeps along in the stillness of the autumnal evening with a rapidity seldom equalled, creating confusion, terror, and dismay along the whole shores. The flocks rise en masse with a fluttering sound which comes strangely on your ear, double and double again, turn and wind over the marsh, agitated and fearful of imminent danger. ”

“ Only rarely does one get a glimpse of this shy little bird, that darts out of sight like a flash at the first approach. Balancing on a cat-tail stalk or perched upon a bit of driftwood, it makes a feeble, husky attempt to sing a few notes; and during the brief performance the opera-glasses may search it out successfully. While it feeds upon the bits of sea-food washed ashore to the edge of the marshes, it gives us perhaps the best chance we ever get, outside of a museum, to study the bird's characteristics of plumage. ”

“ One of the greatest of these field difficulties is that the camera is rarely focused upon the bird to be taken, but is either snapped at random or focused upon some spot to which the bird is expected to return. The latter, in the great majority of cases, is the nest; at other times a much-used perching-place or feeding-ground. Success depends, therefore, very largely upon the nature, disposition, and habits, especially nesting habits, of the particular bird being dealt with. Some birds are of a confiding, unsuspicious nature, and easily reconciled to quiet intrusion ”

“ The habits in confinement, however, make it somewhat doubtful whether the bird is as nocturnal as is asserted, for in the daytime it is quick and lively in its motions, chasing its fellow-captives, dancing round with the tip of its outspread wing or tail held fast in its bill, tossing about dry leaves or pieces of paper, spreading out its wings and thrusting its beak into the ground, kicking with its legs, and finally tumbling about as if in a fit. ”

“ Then the wise bird goes to sleep, and wakes up again only to resume with new zest its persistent and varied efforts, by which it becomes acquainted with all the details of its environment. Watch young birds on the wing gaining their mastery of the air in flight, young seals tumbling in the water, young foals scampering and kicking up their heels in the meadows. ”

“ Early one spring morning he found a nest of this species occupied by one of the birds. Approaching the bird cautiously, he managed to stroke its plumage without its taking fright, so great was its faith in its protective colours. He also succeeded in taking a photograph of the bird, placing the camera a few feet from it. Focussing was accomplished with difficulty, and only by using the eye of the bird as a focal point. The picture is a veritable puzzle. The bird is invisible to most eyes, though plain enough when once distinguished. While the bird was sitting a slight snow fell. ”

“ We can readily understand how the old birds, that have made several journeys and - 270 - must be familiar with all the landmarks, may make the journey without the aid of a supernatural power.
We must remember that the sense of sight in birds is developed to a degree unknown to mankind. It often happens that I startle a ruffed grouse from its perch in the night. In such case it hurls itself through the shrubbery with amazing speed. When I think of the keenness of sight that enables this bird to avoid twigs and limbs, I know that my sight is nothing but blindness in comparison. ”

“ Not surely on the capture of birds, for at that slight elevation its keen eye would detect the movement of a bird at a mere glance; nor has it the dashing flight one would expect to see in a hunter after game furnished with the same organs of motion as itself. ”

“ Their familiar honking is heard long before the thin, wavering, black, V-shaped line appears on the horizon; as it draws nearer, the volume of sound increases, resembling the baying of a pack of hounds, and at last, the flock sweeps overhead with deafening cries; large birds, with long necks fully outstretched, wings beating the air in unison, and all following the leadership of one bird in their journey over their invisible path. ”

“ But if we train our ear so that it catches every fine natural sound, no matter how trifling, we become aware some crisp winter day of a thin see, see, see, often repeated from some hedge, or group of orchard trees. If we watch, our eye will catch sight of one or two tiny creatures, flitting restlessly among the twigs, keeping their wings in almost constant motion, even when not actually flying. The general color of the bird is a shade known in the books as olivaceous, but the effect outdoors and at a distance is a dark gray ”

“ The unfledged bird may stand for a while on the border of its nest, and perhaps open its winglets and attempt to soar away, but his youthful imprudence may, and indeed often does, prove inimical to his prowess, as some more wary and older bird, that has kept an eye toward him, pounces relentlessly upon the young adventurer and secures him within the grasp of his more powerful talons. ”

“ The characteristic cry of the species, spring and fall. It is commonly given by passing or leaving birds. It advertises the species—and a change of policy in the individual according to its loudness. Analogous with notes of other species spoken of as flight notes or identification notes; occasionally heard from an alighted bird. This call is subject to considerable variation, when heard from a bird about to drop down and join others feeding it is comparatively low-pitched and even, leaving or about to leave a feeding ground, highly modulated. ”

“ In the hedgerows and by the wood-sides unfamiliar notes and calls of birds are constantly heard—the notes of young birds, which cannot be identified owing to the thickness of the foliage, and though in the large woods the cry of the young sparrow hawks and the flight of the pigeons and woodpeckers betray their presence, it is almost impossible to watch them, or to ascertain their way of procuring food. ”

“ As to the way, the eye of the bird is like a telescope. It magnifies and sees from very far off. Flying through the upper air the bird watches the line of coast and river, and the instinct that is placed in him says, 'Follow these.' So he follows them, remembering that by doing so he has found a place of safety in other seasons. ”

“ On the ground it is much more drawn out, and a sort of long wailing twitter [3] often precedes and leads up to the final wail. In the air it comes as just a wail without this preliminary.
These birds, then, stand or sit about during the afternoon (but from what hour I do not yet know) in their chosen place of assemblage, and if not occupied in catching insects or preening themselves are dull and listless. But as the evening falls, and the air cools, they cast off their lassitude, think of the joys of the night, there is dance and song for a little, and then forth they fly. ”

“ At intervals large numbers of birds rise up, to hang like a black cloud above the trees for some minutes, but as the evening darkens they all finally settle down for the night; still, in so vast an assemblage there are always many waking individuals, and a noise of subdued cawing may be heard throughout the hours of darkness. With the returning light there is a renewal of the loud noise and excitement, as the birds rise up and wheel about in the air before setting out on their journey to their distant feeding-grounds. ”

“ 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. ”

“ The repast finished, each bird gradually rises to the highest branches of the nearest trees, and remains there until the full digestion of all the food they have swallowed is completed; from time to time opening their wings to the breeze, or to the sun, either to cool or to warm themselves, The traveller may then pass under them unnoticed; or, if regarded, a mere sham of flying off is made. The bird slowly recloses its wings, looks at the person as he passes, and remains there until hunger again urges him onwards. ”

“ His description recorded, proceed to note his manners; whether quiet or restless, whether he jerks his tail, or his head; walks or hops. See what he is doing; picking up insects, digging them from bark or ground, seeking them among flowers or leaves, or whether he is eating seeds from the grass or weeds. Sit there as long as that bird is in sight, and note down everything he does, even his calls and his song as it sounds to you. ”

“ But so closely do the back and outspread wings resemble the dead foliage and sandy soil, that it is almost impossible for the most practised eye to detect these birds when crouching on the ground; and there can be no doubt that it as effectually conceals them from birds of prey. ”

“ Few British birds, indeed, show higher and closer adaptation to special conditions than our dreamy night-jars, essential insect-hawkers of the dusk on open and treeless uplands. Their large and mysterious eyes, their gaping mouths, their straining fringe of bristles, their delicate owl-like plumage, their swift and silent flight, their agile movements, their eerie cry, their curious love-sick nature—all mark them out as marvellously modified nocturnal variants on the general type of the swifts and trogons. ”

“ Whether it be standing in or near a reed-bed, erect, with neck preternaturally elongated and beak pointed upwards, or crouching against a riverside tree-stump, the attitude is calculated to deceive the eyes of all but the keenest observers, especially since the colour of the bird's plumage harmonizes in a remarkable degree with that of the natural surroundings. ”

“ This mysterious bird is also a dweller in lonely places, feeding at night in the woods, having no nest, and laying the eggs in a hollow in the ground or on a stump or log. He is so nearly of the color of wood, earth, and rock, that you may pass near him a hundred times and never see him. Then too, when he perches in the day-time, he does not sit across a branch like other birds, but lengthwise, so that House People and cats cannot see him from below or cannibal birds from above. ”

“ A walk in one of our extensive parks is nearly always rewarded by the sight of one or more of these interesting and attractive birds. They are usually so industriously engaged that they seem to give little attention to your presence, and hunt away, tapping the bole of the tree, until called elsewhere by some more promising field of operations. Before taking flight from one tree to another, they stop the insect search and gaze inquisitively toward their destination. ”
