Nests and Eggs of Birds of the United States Illustrated
Part 10
In the Gulf States, Louisiana especially, according to Mr. Audubon, nesting generally begins in April, and sometimes as early as March. In Pennsylvania, frequently as early as the fifteenth of the former month, except in seasons which are unusually backward, when this important business is delayed until May. The fifteenth of this month marks the time in New England. In Illinois, and other Western States, it begins in early April, while along the Pacific coast, the period ranges from the first to the twentieth of May. Two broods are annually raised in most localities. The second does not, it seems, appear at any regular time, but may no show itself as early as the fifteenth of June, or as late as the middle of September, or during any intermediate period.
The nest being prepared for occupancy, on the ensuing day the female commences to deposit her first egg. This is followed by a second on the next day, when further efforts in this direction cease, and incubation at once proceeds. This lasts for fourteen days, and is chiefly the task of the female. Although the male occasionally takes the nest, yet his principal duty is to supply his mistress with food. When not thus occupied, he is seldom observed on the same tree, but stations himself close-by, where he is ready at all times to answer to her summons. Should the nest be approached by human enemies, the female makes no effort to protect it, but vacates in a. hurry, and silently contemplates, from a stump, or fence-rail, in the immediate vicinity, the intended desecration. The male, however, is more timid, and surveys the scene with the same quiet, sorrow-stricken expression, but from a safe distance. A few days of lamentation, and their troubles are in a measure forgotten. The disappointed couple, if the season be not too far advanced, not to be frustrated in their plans, now seek other quarters, where they hope to achieve the object of their mission in peace and prosperity. In places where the nest is not interfered with, the same spot is chosen on each return of the breeding-season.
There is one feature about these birds that should not be passed over. We refer to their fidelity. Unlike many females, our lady-bird disdains the meaningless flirtations which characterize the actions of so many of our smaller insessorial birds about the mating-time. In no way does she encourage the attentions of other birds, nor will she even tolerate them. The male is not behind his partner in this particular. To show his appreciation of her, a dozen times a day he comes before her presence, parades himself backward and forward in front of her admiring gaze, trails his wings, and, ever and anon, puffs himself up to more than his ordinary capacity. Assured of her pleasure, he temporarily abandons these pompous manouvres, and manifests his regard for her by thrusting his bill into her mouth and discharging therein the contents of his crop.
The love which the male lavishes upon his mate, is none the deeper and intenser than that which the sexes bestow upon their offspring. Few birdies are objects of more special regard upon the parental part. From morning until night the parents are constantly on the search for some racy _tidbit_ to gratify their fastidious appetites. Beetles, spiders, and such like, which are savory articles of meat to a Robin and Bluebird, are not considered fit for these dainty creatures, who must needs be nurtured with food of a more kingly nature. Prepared food, as rich, as nutritious, doubtless, as the honey which the Brazilian Fairy imbibes from painted tulip and chaliced lily, are their portion. Nature does not prepare it as she does the nectar of flowers, and offer it up to their toothsome appetites, but she has endowed the authors of their being with the power so to do. Deep down in the innermost recesses of their bosom exists a churn, which learned men call the _crop_, and here it is prepared. This tempting food consists of a lacteous secretion and the macerated materials of the crop. Its preparation is the work not of the female exclusively, but of both parents. The method of feeding is quite interesting, and after the fashion of the common domestic pigeon. As in this case, either parent thrusts its bill into the mouth of the young, and by a process of regurgitation, forces the contents of its crop into the stomach of the latter. Nor does their food consist always of such a substance, but only during the first five or six days of their existence, for at the expiration of this time, various caterpillars of the measuring-worm family, and other smooth-skinned larvæ, are gathered, and after being completely killed and mashed, are fed to their rapacious appetites. When seventeen days old, the young are able to leave the nest. They are not, however, ready to seek their own fortunes until a fortnight later. Strange to say, the nest-full usually contains a bird of each sex--a beautiful and wise provision of Nature.
Having attained to maturity, the young still linger with the parents in the old, familiar haunts, until the season for departure arrives--about the middle of September--when they leave together. It is nothing uncommon to find several families associating with each other, forming some sort of society, in which the most perfect harmony and good-will prevail.
When captured, either in the young or adult stages, and confined within cages, these birds soon become reconciled to their lot, and make quite agreeable pets. They quickly recognize their keepers, and learn to come at their call. As to the matter of raising them, there does not seem to be any great difficulty. The different kinds of bird-seeds, rape and canary especially, being very nutritious, can be fed to them with splendid results. When vegetation is in season, chick-weed, grasses, and the tender leaves of the common cultivated salad, will be found equally successful. Care must be taken to see that they are also provided with plenty of gravel and fresh water. In confinement as many as four broods have been known to be raised. In his interesting volume on the "Birds and Seasons of New England," Mr. Flagg gives his experience. When a boy he came into possession of one of these birds. At the time of its capture, it was nearly ready to fly. A strictly farinaceous diet enabled him to bring it to maturity. As it grew, it became very tame, and resembled in its actions the young of a domesticated Dove. This bird was always allowed to wander at will. When hungry, it would fly off to a distance, and having satisfied the demands of its being, would regularly return to its accustomed quarters. At length it grew so docile, that it would often fly to its master and sit upon his hand. Other instances of a similar character might be mentioned, many of which have come under our own immediate observation, but we forbear.
The eggs of this Dove are of an elongated oval form, nearly symmetrical at each end, and of a pure-white color. A clutch from Pennsylvania measures respectively 1.18 by .87 and 1.20 by .88 of an inch. Specimens from Texas, California and Maine manifest not more than ordinary variations of size. The largest egg, out of four sets which were sent to us from the Pacific coast, has a length of 1.21 of an inch, and a width of .86; the smallest, .97 by .84 inches. The same difference holds reasonably true with respect to samples from other localities.
Plate XX.--TINNUNCULUS SPARVERIUS, (Lnn.) Vieillot.--Sparrow Hawk.
|The Sparrow Hawk is the handsomest of American birds of prey. Few small species are more active in the pursuit of quarry, and none more friendly and sociable in their intercourse with man. It receives its common name from the fringilline character of its fare, our various Sparrows forming a no inconsiderable portion thereof.
From Maine to California, and from Hudson's Bay to the Mexican possessions, these birds abound in greater or less abundance, but are notably scarce, or entirely wanting, in the Arctic regions of British America, and in our newly acquired territory of Alaska. The highest points which they have been supposed to reach are Fort Resolution, on Great Slave Lake, and Fort Rae. Throughout nearly the whole of this vast region they undoubtedly summer, and spend the time in the rearing of families.
Within the United States the species is a _rara avis_ in some places, and a very abundant one in others. In the vicinity of Calais, Maine, it is quite common, which is otherwise the case in Eastern Massachusetts, although in the western parts of the latter State, birds have been known to breed. In the Middle Atlantic States, New York and Pennsylvania especially, it is a not uncommon occurrence to find it in great plenty, often as many as a dozen paired individuals being seen within a single square mile of territory. Throughout the West, but more particularly in the canyons of the eastern range of the Humboldt Mountains, Ridgway attests to its abundance, and also to its disposition to nest in hollows of limestone cliffs.
On the approach of winter these birds desert the northern and middle sections of our country, and mostly retire to warm southern latitudes beyond Virginia. According to Mr. Samuels, they are permanent residents of the lower districts of New England, although but slightly so in cold weather, if the observations of other writers of equal prominence are to be relied upon. In Florida they are found at all seasons, but mostly in the higher latitudes of the State during the breeding-season. West of the Rockies, and in the region watered by the "Father of Waters" and its numerous tributaries, they are probably but transient occupants; yet there seems to be no strong reason why they should not find comfortable winter-quarters in Southern California and in the regions situated between the same isothermal lines. When the Western history of this species has been more closely studied, this will doubtless prove the case.
The period of migration in the Middle Atlantic States seems dependent upon climatic influences. When the season is tardy by reason of long, cold winters, the birds do not arrive until after the middle of April; but when the weather is fine, and the prospect favors a continuance thereof, they ordinarily make their appearance early in the month. In New England, doubtless somewhat later, if the time of laying forms any argument upon which to base a conclusion.
Upon its arrival in the vicinity of Philadelphia, the species takes up its abode in old orchards chiefly, where it can be convenient to the homes of man. While here it destroys immense numbers of field-mice and noxious insects, and is certainly one of our foremost feathered benefactors. To be sure it will destroy a few young chickens occasionally, by way of changing the monotony of its life, but the immense good which it otherwise accomplishes, should induce humanity to throw a veil over its thoughtlessness and imprudence, and extend to it a cordial welcome. So small a bird could hardly perpetrate much mischief, and therefore should not be dreaded. Its many visits to the farm-yard are not made solely with the view of depredating upon the poultry, but for the purpose of feeding upon the vermin which infest the out-buildings, and which are so destructive to the garnered grain. These visits should be encouraged by all means. The adult chicken is too heavy a burden for such apparently frail creatures to bear away, and as for the young, they are generally too well guarded by the parent, to become very easy victims. It is only when the chicks have been scattered, that this Hawk has the audacity and hardihood to venture an assault upon the brood. Unlike many species, our little friend does not pursue its prey, but prefers to watch for it while perched upon a dead tree, or on a projecting twig. Here, solitary and alone, it will remain for hours, without perceptibly changing its position. The only motion visible at the time, is a peculiar jerking of the tail, which seems to betray an over-anxiety for something to turn up. A very common place of resort is a clump of bushes, or a hedge-row. The abundance of small birds which seek such situations being the cause of the attraction thither.
Thus the sexes keep apart from each other, and feast on the fat of the land, until the latter part of April, or the beginning of May, when the male, who is the first to abandon this selfish mode of life, desists therefrom, though hardly without a great effort, and prepares to lead the way by calling his partner from her near or far-off feeding-grounds. Standing upon a dead branch in an open situation, he sounds his peculiar call-note, at somewhat irregular intervals, and, anon, turns himself round as though to catch the well-known response, or to see the agreeable presence. For hours at a time he may be thus seen where undisturbed by bird or man. If no reply is elicited, he darts away in great hurry, and tries his fortunes elsewhere. This is usually the case with young males. But with old birds the rule is different. They mostly select the partners of past years, and there is always less formality in renewals of plighted vows. The suits of the younger and more spirited males are often attended with considerable difficulty. This arises chiefly from the fickleness and waywardness of the young females, who seem hard to woo, and who often indulge in cruel flirtations, much to the annoyance of their respective suitors. These little pranks upon their part are generally of short continuance, and soon decided one way or the other. If settled in favor of the several actors, the latter become highly elated, and give expression to their feelings in the most ridiculous manner. The females now become as unwavering and devoted in their fidelity and affection as they were before changeable and whimsical. The period of courtship seldom exceeds two days at the utmost. While it lasts, the birds make short tours around the country, and on their return settle down to the prosy realities of wedded life. A suitable spot must be selected for a home. Although both birds spend no little time in searching for one, yet the matter is generally and wisely left to the judgment of the female.
They are never known to construct homes for themselves, but make use of hollow trees, Wookpeckers' holes, and often the old and forsaken nests of the common Crow and the Gray Squirrel. A low, flat shelving of rock beneath an overhanging bluff, in situations remote from the dwellings of man, is not unfrequently chosen. But in' places immediately surrounding him, and even within his precincts, unfinished stone-buildings and pigeon-cotes are occupied, the latter much to the dread of their rightful owners, who soon become reconciled to the glaring insult, and live on friendly terms with their courageous neighbors. In Germantown, Pa., many of these birds are accustomed to deposit their eggs in the holes left by the removal of scaffolding from the walls of unfinished buildings. In some instances, they are placed within a slight depression produced by the removal of the mortar; but, generally, a thin covering of leaves and grasses serves to relieve the roughness of the cavity. In one case a rather dense bedding of moss made a soft and cozy lining. Almost any tree that has been pressed into service by the Golden-shafted Woodpecker, and made to answer as a receptacle for its eggs, is utilized by the species under consideration. In an orchard, the apple is mostly a favorite; while in other situations, the swamp maple and common chestnut are as frequently occupied. Their height above the ground varies from ten to fifty feet. In no cases have we discovered it below this figure, and never above it. A nest found April 20th, 1881, near Rowlandville, by William Wentz, in a decayed chestnut branch, was fifty feet from the ground, and consisted entirely of dry grasses in quite limited quantity. This is the earliest one ever found in this locality. Generally, the nest is completed for oviposition during the last of this month, or the beginning of the succeeding. My son, Alan F. Gentry, on the fourth of May of the same year, met with one in a hollow branch of the chestnut, in Germantown. This was placed about twenty feet up, in a cavity whose width at the mouth was four and a half inches, and whose depth was nine inches. It was lined with a few leaves and fragments of decayed wood, and contained four eggs, which were partially incubated. Another complement of eggs, five in number, before us, was found May 17th, 1880, near Granville, N. Y., by F. T. Pember, Esq. It was placed in an isolated maple, about twenty feet from the ground, in what was once the home of a pair of Flickers. The bottom of the cavity was lined with straw and grass of last year's deposit, little, if any, fresh materials being noticeable. The diameter of the base was seven inches, and depth, twenty inches. The drawing represents a nest in a decayed branch of the red maple. The female bird is considerably reduced, and placed on the edge of the cavity, looking outwardly; whereas the male, in perfectly erect attitude, and with dignified demeanor, stands on a bent branch, at some distance from his home, engaged, as it were, in surveying the surrounding scenery. He is shown in his jauntiest feathers, and with his fair proportions diminished but one-fourth. Owing to the difficulty encountered in figuring the eggs _in situ_, we have been compelled to show a single specimen, the natural size, and on a tinted background below and to the left of the picture.
The nest being ready, the female is not dilatory about laying. Unlike most of the birds which we have previously described, she does not deposit with much regularity. Sometimes the eggs are laid on consecutive days, and, at other times, on each alternate day; never more than one being deposited daily. This business being accomplished, the female proceeds at once to incubate. After she has been thus occupied for a varying period of time, seldom less than two hours at a sitting, she summons her mate to her side, and resigns to him the laborious task for a season. While one is on the nest, the other, when not in quest of food, is on a tree in the immediate neighborhood, quietly on the alert. If danger is imminent, the sitting-bird is apprised of the fact in time to make its escape. This done, the two endeavor to protect their home from pillage. As long as there is some prospect of frightening away the depredators, they keep up the warfare with a good show of courage. But when constrained to desist from the attack by the too near approach of enemies, they do not forsake their home entirely, but choose a point out of reach of harm, where they station themselves, and behold with profound distress its demolition. In these attacks the female is the superior of her masculine companion, and exhibits the most reckless bravery. The latter is, however, more circumspect and cautious. But should the enemy be a feathered species, and of superior physique, the unequal warfare is waged with terrible fury, and often results in favor of the defendants. Where not interfered with by man, these birds have been known to visit the same locality year after year; but when meddled with, they abandon the site for another of greater security. The period of incubation ranges from fifteen to sixteen days.
The young are very helpless creatures when first hatched, and often tax the patience and vigilance of the parents to the utmost in their efforts to obtain for them a _quantum sufficit_ of nourishing food. Both birds are seldom absent together on this important mission. While one is abroad, the other remains at home, and exercises the strictest surveillance. The food of the young at first consists of grasshoppers, crickets, and caterpillars of the family of measuring-worms. Being rapid growers, they are soon able to digest bits of small rodents and birds, which the parents tear from the warm flesh of the quivering victims which they hold in their talons. When four weeks old, parental assistance is in a measure withdrawn, and they are forced to feed themselves. A fortnight longer, they quit the nest, and receive their meals while perched on the tree-branches. But it is not until they attain an age of two months that they are entirely thrown upon their own resources. They, however, continue to reside with their parents, but for what length of time, we are unable to say. Like the latter, their appetites are very fastidious, tainted and unsavory food being rejected with disgust. When the young have vacated the nest, Audubon asserts that the parents are known to imitate their feeble cries, as they travel together in pursuit of game. Ordinarily, the cry of the adult birds is a peculiar series of notes, which are pronounced in a very shrill manner, and most difficult of imitation. It is said to resemble the call of the European Kestrel, and would doubtless be mistaken for it, were it not for its more powerful intonation.
When taken from the nest, these Hawks are readily domesticated, and make very interesting pets. Audubon once reared a young bird, which he kept about the house. At nights it would roost upon a favorite window-shutter. In the daytime it would wander about the fields, where it was often assailed by its wilder kindred. On these occasions, instead of making a stand and resenting such uncivilized conduct, it would invariably beat a precipitate flight to the house where it was sure of finding protection. At length this poor bird was killed by an enraged hen, one of whose chicks it was essaying to capture. While in Columbia, South Carolina, Dr. Coues saw three of these birds in the possession of a neighbor. They had been taken while quite young, and were perfectly reconciled to their imprisonment. During early life they ate all kinds of meat, but as they approached the age of maturity, they began to display much of their natural disposition. When disturbed they would show their displeasure by snapping the bill, and clutching at the offending cane with their talons. Among the number there was a cripple who was most dreadfully misused and bullied by his companions. One night, being insufficiently fed or unusually irritable, they set upon the poor fellow, killed him, and had nearly made way with him by the returning morn.
