Part 19

Toward the close of March, or in the beginning of April, the hens separate from the males, and seek for themselves nesting-places in secluded localities. The nest is anything but an elaborate affair, consisting of a few dry leaves or grasses scratched into a depression by the side of a prostrate log. Here the eggs--twelve beautiful, oval, speckled treasures--are laid, and for thirty long, weary days and nights they are sat upon by their author in her efforts to warm them into life. When she leaves them, which she does a short time each day for food, she always takes the necessary precaution to cover them with leaves, as a protection against cold and intrusion. Nothing will tempt her to quit the nest when the young are about to be hatched. So absorbed does she then become that she has been known to submit to capture rather than endanger the lives of her offspring.

No human mother manifests deeper affection for her children than does this bird of the prairie for hers. She fondles and dries them after they have escaped from their prison-houses, and tenderly helps them out of the nest. It is now that her cares may be said to commence. Where their interest and well-being are concerned, hardly any responsibility is too great for her to assume. She leads them into pleasant pastures, teaches them to know good from bad foods, and acquaints them with all the devices and subterfuges practised for eluding man and other enemies. But it is not long that they are thus subservient to maternal wisdom and forethought, for in fourteen days they are old enough to scratch for a living, and to seek shelter and security from lawlessness and cruelty. Their _menu_ consists of wheat, berries, grasses, earth-worms, and all kinds of terrestrial insects.

When summer is over, the different families of the same neighborhood come together, unite in one large flock, and travel over the country for food. The males emerge from their meeting-places and join the moving army, and parents and young have nothing to do but to feed vigorously and grow fat. Late in October, or early in November, they begin to attract the attention of gunners, and thousands are killed for the market, where they are in eager demand by all lovers of good living.

AMERICAN OSPREY.

_Pandion haliætus_, as the Fish Hawk or Osprey is called in ornithological language, is found from the fur region surrounding Hudson’s Bay to Central America, and from Labrador to Florida, excepting Boston Harbor, on the Atlantic Coast, and almost from Alaska to the southern extremity of the peninsula of Lower California on the Pacific seaboard. Birds have been known to nest on the rocky islands of California, and about Sitka, according to Bischoff, as well as along the small streams in the vicinity of Nulato. From Long Island to Chesapeake they breed in vast communities, which often number several hundred pairs, but away from the sea-coast they are only occasionally met with on the margins of rivers and lakes. Dr. Hayden found several pairs nesting on the summit of high cottonwood trees in the Wind River Mountains, and Mr. Allen observed the birds particularly abundant about the lakes of the Upper St. John’s River in Florida, six nests being noticeable within a single circle of vision. Salvin claims that they nest on both coasts of Central America, but more especially about Balize, although on the islands of Trinidad, St. Croix, Jamaica and Cuba they are seen at all times except during the breeding-season.

Below Philadelphia, and in the south-eastern counties of Pennsylvania bordering on the Delaware, individuals have been occasionally observed. Their arrival is about the beginning of March, often when the streams which they frequent are fettered with icy bonds, and their departure occurs about the twenty-fifth of September, and frequently, especially when the weather is remarkably fine, as late as the fifteenth of October. Well-established communities, numbering more than fifty pairs, have been met within the swamps of Southern New Jersey, among whom the best order and most perfect harmony prevailed. Few species display less shyness and greater confidence, or are more eminently social, as is particularly shown when these birds take up their quarters in close proximity to occupied dwellings, or by the side of frequented by-paths and highways. Where undisturbed, the same localities are visited year after year. Their exclusive piscine habits secure for them free and unlimited sway in their carefully chosen abodes, for the poultry has nothing to fear, and the smaller birds are not intimidated by their presence and sent screaming to their coverts as they do even when pursued by the little sparrow hawk. Wilson cites a case where four nests of the common purple grackle were built within the interstices of an Osprey’s nest, and a fifth on an adjoining branch, and the Osprey was quite tolerant of such intrusion and freedom. The writer has observed a nest of the grackle built in a similar position, while all around the great Hawk’s home, and scarcely five rods distant, were nests of the robin, wood thrush, red-winged blackbird and others, and no annoyance was known to occur, the Ospreys carefully attending to their own business and scarcely noticing their more humble brethren.

Their bitterest enemy is the white-headed eagle, against whom the united attacks of many of these birds are concentrated when he has the audacity to venture within their hunting-grounds or breeding-quarters, for they are too familiar with his powerful muscularity and courageous disposition to attempt a single attack. When an Osprey is pursued by this king of the forest and hunting-ground, his loud, vociferous cries of distress, resounding far and near, evoke an army of defenders, who come with all possible speed to wreak vengeance upon the great arch-enemy of their pleasures and happiness. These attacks are made for the purpose of compelling the Osprey to drop his prey or disgorge, which the superior bird, if his efforts have been successful, pounces down upon and seizes before it has had time to reach the water or ground.

Powerful as the flight of the Fish Hawk is, yet it is never very high, nor much protracted. While skimming over the water’s surface, even at a moderate elevation, his quick eye soon descries his quarry, and, in an instant, he pounces down with tremendous force below the water’s level, often to a great distance, but seldom missing his prey. Arising from his watery bath, he moves off to a suitable perch to digest his meal at leisure. But should the movement attract the keen vision of the bald eagle, who is generally waiting in some secret covert, or sailing so high up in the air as to be almost invisible, the Osprey swallows his victim if small, or seeks to bear it away in his talons to a position of shelter and safety, but, rather than endure the too near approach of his more powerful relative, drops it to the infinite delight and great satisfaction of the latter. Where a suitable tree, or a commanding stump, presents itself by the side of his chosen fishing-grounds, he may be seen perched thereon for hours together, gazing into the liquid depths below for the finny tribes that sport therein, and ever and anon swooping down with amazing velocity and bearing up in his resistless talons the squirming victim. In shallow places his mode of capture is regulated in conformity with their character, gliding over their surface and clutching at his victims as they come within sight.

The food of the Osprey consists mainly of fish, although the reptiles and batrachians that inhabit the swamps and marshes wherein he builds do not escape his vigilance. Almost all kinds of fish, except the very largest, which would be more than a match for his strength, are captured and devoured with avidity. We have watched with a great deal of interest and pleasure his piscatorial pursuits on the shores of Delaware Bay, and have often seen him bear from great depths fish much larger than the common shad. The latter, together with the herring, striped bass and black bass, are favorite articles of diet, while his catchings from fresh-water streams, the larger cyprinidonts, cat-fish and pumpkin-seed, are quite as great luxuries.

When the nesting-time comes around, the last of April or the beginning of May, these birds are not so engrossed with the thoughts of feeding as to be utterly oblivious of the duties which it imposes. Generally the same nest is selected year after year, but when a new one is to be constructed it is not uncommon to find many pairs engaged in its building, the friends of the destitute assembling and laboring with the most determined energy till its completion. A more sociable disposition could hardly be conceived. The spirit which would lead these birds to fly to the assistance of a distressed companion would certainly induce them to co-operate with their brethren in the difficult task of nest-building, especially when such a bulky structure as the species is known to construct would severely task both the time and patience of the pair which is to occupy it. The vast amount of labor and time expended in rearing such a fabric is a sufficient inducement for them not to want to indulge in such employment any more than is absolutely necessary. Hence these nests are constructed for durability. Unlike his European congener, whose nest is placed upon a high cliff, the Osprey almost invariably builds on trees. All nests taken by the writer have seldom been at a greater elevation than fifteen feet, although instances have been recorded where they were twice that height. It is a remarkable fact that the trees supporting these nests are always dead and generally placed in the midst of marshy ground, either completely isolated or surrounded by a dense growth of bushes. At all events, they occupy rather conspicuous positions. It is probable that the excrement of the birds or the saline character of their food has much to do with killing the nesting-trees. Trees which seem vigorous and thrifty at first manifest after a year’s occupancy unmistakable signs of death. Not always are trees selected for nesting purposes, for a Mr. W. H. Edwards describes a nest built on a tall cliff on the banks of the Hudson River, not very far from West Point.

Externally the nest is composed of large sticks piled to a height varying from two to five feet, and measuring fully three feet in diameter. Corn-stalks, mullein-stocks and bark are occasionally intermingled with the sticks, but within there is a rather profuse lining of sea-weed and the long grasses which grow so luxuriantly in salt-water marshes. The cavity ranges from fourteen to fifteen inches in diameter, and is unusually shallow in proportion to the size of the nest.

Three eggs constitute the usual nest-complement, although two are sometimes laid, and rarely four, and these are deposited on consecutive or alternate days, at the rate of one egg a day. They measure about two and one-half inches in length and one and three-fourths in width, and are of a yellowish-white color, thickly covered with large blotches of different shades of brown. Incubation follows close upon the last deposit, the task being begun by the female, and devolving principally upon her, although the male occasionally relieves her for a brief spell each day. While she is on the nest, he is a jealous husband and a most faithful provider. The choicest catch of his piscatorial exploits is carried directly to the nest and ungrudgingly administered to the patient sitter. When not engaged in providing for their wants he stations himself upon an adjoining tree, if such should happen to be present, or somewhere in the immediate neighborhood, and exercises the closest surveillance over the nest and its occupant. All attempts at intrusion are most summarily punished. Dr. Brewer mentions a case where a lad essayed to reach the nest in order to rob it of its eggs, when he was assailed with so much violence that the male’s talons were driven through a cloth cap that he wore and laid bare the scalp. Experience has proved the risk incurred in visiting these nests with hostile intentions. You may pass and repass underneath the nest, the authors criticising your every movement the while, without calling forth the slightest opposition. When, however, you attempt to mount the tree that contains their cherished treasures, you virtually invite the full measure of their wrath. That the male is affectionately devoted to his partner is shown by Wilson in a case which he cites of a female who was prevented from fishing by a broken leg and that was abundantly supplied with food by her mate.

When the young appear they are objects of more than common parental solicitude, the parents vying with each other in rendering them every needed attention and in providing them with a plentiful supply of suitable food. But one parent is absent from the nest at a time, the other remaining at home to guard against danger. They are ravenous feeders, and soon attain to full development, when they resemble very closely in dress their parents, having the upper parts spotted with pale reddish-brown or white. Adult birds are dark-brown or grayish-brown above, with most of the head, neck and under parts white, the chest in the female, and sometimes in the male, being spotted with brown. The tail, usually paler than the back, has six or seven dusky bars, and is tipped with white.

That these birds may be fitted for powerful flight they are provided with long and pointed wings, the second and third quills being the longest. They have a stout bill, with a very long hook and sharp end. Their feathers are oily to resist water, those of the head being lengthened and pointed, and of the thighs and a little of the front parts of the tarsi short and close together. The legs, tarsi and feet are very strong and robust, and the claws all of the same length and very large and sharp. Rough scales completely invest the tarsi, and the toes are padded below and covered with numerous hard-pointed projections to aid in holding their slippery prey. The iris in some specimens is reddish, but mostly yellow; the bill and claws blue-black, and the tarsi and toes grayish-blue. Male birds are not so large as the females, the latter measuring twenty-five inches in length, and with an extent of wings of fifty-two inches.

TURKEY BUZZARD.

Few species, if any, have a wider distribution in America than the Turkey Buzzard. It is found more or less abundantly to the Saskatchewan throughout North America, from the Atlantic to the Pacific Coast, and in all portions of South America as far south as the Strait of Magellan. Individuals have been met with in Nova Scotia and New Brunswick, though these birds are generally not common north of Central New Jersey. From Eastern Maine, in the neighborhood of Calais, to Connecticut, specimens have occasionally been captured. In a single instance, Mr. Lawrence observed a small company of nine at Rockaway, Long Island. West of the Alleghenies, from Central America nearly to the Arctic regions, it occurs more abundantly. Without exception, it is found in greater or less numbers in all the Middle, Western, Southern and North-western States. From Lower California to Washington, along the Pacific, numerous parties attest to its common occurrence. The West Indies, the islands of Cuba, Jamaica and Trinidad, the last-named in particular, include it within their faunæ. Honduras and Guatemala, as well as the Falkland Islands, off the eastern coast of Patagonia, are permanent residing-places.

In Pennsylvania and New Jersey, where the writer has had abundant opportunities for studying the species, these Vultures summer quite plentifully. From their first appearance, in March, large numbers may be seen high up in the air, moving in large circles, apparently exploring the ground below for their favorite articles of food. In rural districts they are, however, more frequently observed than in the vicinity of densely-populated towns, the greater abundance of carrion to be met with in the former places doubtless being the cause of this preference. But in California and Oregon, according to Dr. Newberry, they are quite as common near towns as about the large rivers. In our Southern States they visit cities and large villages, and play the part of scavengers in company with the black vulture. They are said to be so tame and unsuspicious in Kingston, Jamaica, that they roost upon the house-tops or prey upon offal in the streets. In country places they are no less familiar and trustful, as is evidenced while feeding. So intent upon their business are they at this time that the presence of human beings is unnoticed, and even when forced to forsake their booty they sullenly repair to a short distance, only to resume their feeding when the annoyance has passed. The common crow has been observed to gather around the same food, and the utmost good-feeling prevailed. A small flock will often settle down upon a dead horse around which several dogs have gathered. The snapping and snarling of the dogs, when they approach them too closely, do not cause the Vultures to retire, but only to step a few paces aside, when, nothing daunted, they continue their feeding, apparently oblivious of their whereabouts and surroundings.

Although the sense of sight is rather keenly developed in these birds, yet that of smell is none the less so. This is an advantage, for both the visual and olfactory organs seem requisite in the determination of the presence of decaying animal matters. As a proof that smell leads to food-detection, Dr. Brewer cites an instance, on the authority of Dr. Hill, where several of these birds were attracted to the house of a German emigrant who was prostrated by fever, being drawn by the strong odor escaping from his neglected food which had become putrid. Mr. G. C. Taylor, whilst a resident of Kingston, sufficiently tested their power of smell. He wrapped the carcass of a bird in a piece of paper, and flung the parcel into the summit of a densely-leaved tree, that stood in close proximity to his window. A moment or two only elapsed, when the keen smell of these birds scented something edible, but they were unable to find it, obviously for the reason that it was hidden from view by the enveloping paper.

Generally their food consists of all kinds of animal matter. They are often accused of sucking eggs, and also of eating the young of herons, as well as those of other birds. In Trinidad, they are said to live on friendly terms with the poultry. As no breach of faith has been reported to have occurred in this instance, it is not likely that they would molest in any way our smaller birds, at least we are not cognizant of any such cases of interference from our own observation, nor do we find them in the recorded experiences of friends. They are worse-disposed, it seems to us, to their own kith. When several are feeding together, most violent wrangles occur over the booty. Each strives to get the lion’s share. It is amusing to witness their manœuvres. Some luckless fellow has just discovered a choice and racy bit, which he is endeavoring to make off with in a somewhat hurried manner, when instantly he is beset by a near companion, who has scarcely swallowed his own morsel. A conflict ensues. The latter, being the stronger, succeeds after a little in defrauding the other of his rightful property. When gorged, these birds are stupid and indisposed to exertion, the period of digestion ordinarily being passed in a motionless, listless attitude, with half-opened wings.

Recovered from their semi-stupid condition, they do not at once go to feeding again, but spend a long time in the healthful exercise of their volant appendages. Few birds are more graceful, easy and dignified while on the wing. On the ground they may seem awkward, but it is while soaring at a great height above the earth that they are seen in all their glory. When prepared for lofty flights, they spring from the ground with a single bound, and, after a few quick flappings of wings, move heavenward. Attaining a great elevation, they cleave the ether in ever-widening circles, or sail on nearly horizontal wings, the tips being slightly raised, with steady, uniform motion. These aerial diversions, for such they seem to be, are never performed singly, but in small parties of a dozen or more, being more common in early spring, and at the close of the breeding-season, than at any other time. It is to be observed further that these movements are executed in silence, the only sounds which the Buzzards are capable of producing being a kind of hiss, which has not inaptly been compared to the seething noise emitted by plunging a hot iron in a vessel of water.

When ready to breed these birds look about for a hollow tree, or some stump or log in a state of decay, either upon the ground, or slightly above it. Generally, there are no indications of a nest. In occasional instances a few rotten leaves, scratched into the hollow selected for the deposition of the eggs, constitute the nest, these treasures being laid without any previous care for their preservation and shelter being taken. In Southern New Jersey the nest has been inadvertently strayed upon in the midst of a deep and almost impenetrable morass, where it was found placed upon a hollow stump. Within the rocky caverns along the wide, shallow Susquehanna, as many as a dozen nests have been counted in a few hundred yards of space, often as early as the last week of March in favorable seasons, but generally not till the middle of April. When the winters are not extremely rigorous, a few individuals remain in the vicinity of their breeding-quarters throughout the entire year. We have found the birds breeding in Delaware County, Pa., towards the latter part of April or the beginning of May, but in Philadelphia they rarely do, if they breed at all. In Southern Ohio they are a common summer sojourner. Speaking of the birds in Jamaica, Mr. Gosse says they nest in depressions in the rocks and in the ledges thereof, in retired localities and also upon inaccessible cliffs. On Galveston Island Audubon found the birds nesting in great numbers, either under wide-spreading cactus branches or underneath low bushes in the midst of tall grasses in level saline marshes.

In the vicinity of Cheraw, S. C., Dr. C. Kollock met with the black vulture and our present species in swamps and dense forests, where they congregate in vast numbers throughout the entire year. These places are commonly designated Buzzards’ roosts. Audubon once visited one of these roosts in the vicinity of Charleston, which covered more than two acres of ground, and which was completely denuded of vegetation. On the banks of many of the rivers of Southern Texas, Mr. Dresser found them nesting in large numbers, the timber along their borders constituting comfortable and secure shelter; but, contrary to what has always been entertained, he affirms that they build large and bulky nests of sticks, which they place at great heights in an oak or cypress, close by the river-banks. Captain C. C. Abbott says that in the Falkland Islands the eggs are deposited in the midst of bushes beneath high banks, or on the summits of decayed balsam logs, during the early part of November. In certain localities, where the birds are not very common, paired individuals are not infrequently found.
