Plate XLIII. CYANOCITTA CRISTATA, (Linn.) Strickl. Blue Jay.

Previous

This abundant, beautiful and familiar bird is a resident of the eastern half of North America, from the Atlantic west to Kansas, Eastern Nebraska and Dakota, and from Florida and Texas on the south to the 56th parallel of north latitude. Wherever met with it breeds in greater or less numbers, according as its presence is welcomed or rejected by the imperious lords of creation, and food is readily or with difficulty obtained.

Few species show more striking peculiarities of conduct, and none scarcely exhibit as much sagacity and intelligence. Within its natural haunts it is exceedingly shy and suspicious, and is hardly approachable. Frequent intercourse with man, however, has, in some sections, modified its disposition, and, as a necessary consequence, confidence has taken the place of distrust. This is substantiated by its tendency to nest in places contiguous to the dwellings of man. In Eastern Pennsylvania, a decade ago, it was quite a common occurrence to find a score of birds nesting in a square mile of territory, but, at the present time, the collector considers himself very fortunate if he encounters one-fifth of this number within the same area, and these only in localities whose solitude is seldom unbroken by the tread of human footsteps. In the wooded regions of Iowa, Mr. Allen found this species quite as trustful as the Black-capped Titmouse, and in Illinois, reduced to a semi-domesticated condition. Within the former State a pair of birds were found nidificating under the window of a house, in a lilac-bush, and this, too, in one of the most prominent and frequented streets of the town of Richmond.

A curious behavior marks the species' first acquaintance with human society. The movements of man are followed with noteworthy pertinacity, the slightest action being carefully scanned, but our feathered friend never ventures too near at first. After frequent interviews at a wary distance, if undisturbed, he gradually approaches nearer and nearer, and in time comes to regard him with kindly favor. Sometimes these advances are received with coldness, and the most bitter persecutions occur. When such is the case, the Jay takes a dislike to man, and shuns his society. In his rural retreats this bird is the enemy of the hunter, and often provokes his ire and vengeance by its tantalizing behavior. When he is in pursuit of game, it takes great delight in following him, and, by its seemingly distressing cries, seeks to warn its feathered neighbors of approaching danger.

Though occasionally found within cultivated regions, yet these birds affect the shelter of dense forests, where they can pursue their craft with undismayed tranquillity. It is in such quarters that they are mostly to be seen in winter, searching for the eggs of insects. When there is a scarcity of such diet, the fruits of the oak, beech, birch and pine are hunted and devoured. Large numbers of beetles, some terrestrial in habits, also contribute largely to their sustenance. With the return of spring, insect life is more rife, and we find them feeding upon grasshoppers and caterpillars of every description. Like the Crow, the Jay is pre-eminently omnivorous, although preferring animal to vegetable matters. In the gratification of its appetite for the former, it is led to destroy the eggs and young of smaller birds, and even to kill those that are full-grown. Such merciless conduct detracts from its general good character, and often conduces to its destruction. But the good which it accomplishes, as evidenced above, outweighs in tenfold proportion the mischief committed, and should encourage us to desist from our persecutions, and accord to it a generous welcome. Its depredations upon the garden and farm are so trivial, that they do not warrant the abuse which thoughtless farmers are wont to lavish upon these feathered benefactors. To favor our readers with some idea of the good which has been accomplished in some portions of the country, we cannot do better than give the substance of Dr. Kirtland's estimate of its character, as given by Dr. Brewer. When the former gentleman first settled upon his farm he observed that every wild cherry and apple tree was well-nigh denuded of its leaves by the tent-caterpillar. The evil was so widespread that all efforts to counteract it seemed hopeless. At this crisis the Jays made their appearance and established colonies. The caterpillar constituted a ready diet for their young, and was preyed upon so extensively, that in a short time, not one was seen in the neighborhood.

Whilst feeding, the Jay is both silent and vigilant, save when disturbed, when he signifies his discontent by a harsh, petulant cry, which sounds like djay, jay, jay. In his more complaisant humor, he is by no means an unmusical fellow, but gives expression to a series of vocal sounds which for variety beauty and harmony are truely creditable, and, as Nutall happily notes are by no means unpleasant, and fall in harmoniously with the cadence of the feathered choristers around him, so as to form a finishing part to the general music of the grove. Wilson likens him, among singing-birds, to the trumpeter of the band. His notes are anything but monotonous. At one time he screams with all his power as if actuated by some terrible impulse, and, almost the next instant, greets you with notes as soft and pensive as those of the Bluebird, but to be only followed by others that fairly shock the ear with their unutterable harshness. The latter have been observed to resemble the syllables whÈÈo-whÈÈo-wieeo, but the sweet bell-like note almost baffles the powers of description His powers of mimicry, though different from those of the Mocking-bird can hardly excelled by that species. The cries of the Sparrow Hawk are imitated with great pleasure, and so accurately does he mimic the harsh screams of the Red-shouldered and Red-tailed Hawks, that the smaller birds seek their coverts in dismay, and the poultry are thrown into the greatest consternation. When reared from the nest these birds make interesting pets, and in due time learn to simulate every sound they hear not even excepting those of the human voice. A case is cited by Wilson of an individual that had been raised by a South Carolinian, which evinced remarkable intelligence, and which possessed nearly the loquacity of some of the Parrots. It could pronounce several words with remarkable distinctness, and when called, would respond to its name in quite a sociable manner. By fanciers the Jay is esteemed the most ingenious, artful and teachable bird with which they have met.

A peculiarity of the species, deserving mention, is the habit of the sexes to go together during the winter, showing that some kind of attachment exists, even at the period when many birds, not gregarious, find it most to their interest to lead solitary lives. This disposition to go in pairs may be the beginning of a tendency to gregariousness, such as prevails among some of its near cousins, or it may be considered as the last vestige of a habit that was once predominant. Cases have been observed where the sexes dwelt apart, which leads to the suspicion that the species is surely and inevitably gravitating towards such a state. In the season of cold and scarcity, when most of our resident birds are too much concerned with the procurement of food to permit the social relations to have a moment's sway, the life of a celibate seems to be more fitting, and in very many cases is one of preference. While these birds thus continue to keep together, possibly through force of long-established habit, yet they do not manifest the slightest tendency to matrimony, until Nature has sufficiently recovered from torpor to insure a living for their offspring. Not very fastidious in appetite, and easy to please, almost any kind of insect diet answers. Consequently, with the early dawning of April, but never later than the fifteenth of the month, a change comes over them. Less anxiety is manifested for food-matters, and more friendly relations established. The sexes consort together much, and after a few days of courtship, which business is seemingly unmarked by any great display of form, settle down to the prosy realities of life. Nidification is now entered into with commendable zeal. For this purpose a forest or orchard tree is generally chosen, although a low bush is sometimes made subservient. In retired localities a preference is shown for the pine. The selection of a site never consumes much time. With old birds it requires careful and diligent searching for a day or two, but in the ease of inexperienced individuals, the time may be protracted for nearly a week. Where permitted to rear their progeny unmolested, a strong attachment is shown for the same neighborhood, and instances occur where the same pair dwell and breed in some cherished haunt for several years in succession.

In the construction of a home both birds labor with the utmost diligence. They are usually about three days thus occupied, each bird taking an equal share in the task. The nest is anything but elaborate in its mechanism, and has little to recommend it in artistic design and beauty. It is a strong, coarse structure, placed upon a branch over a crotch, sometimes held in position by adjoining twigs, and is composed of sticks rudely and firmly interwoven. Inside there is usually a lining of dark fibrous roots. In proportions it is almost equal to the nest of the Purple Grackle.

The domicile being completed, on the following day, sometimes not so soon, the female begins to lay, at the rate of one egg a day, her complement of eggs. This is usually five, although nests have been found with six, and others more rarely with four. Incubation is closely attendant upon oviposition, and generally dates from the day following the last deposit. This business is the sole labor of the female for about seventeen days. While she is thus occupied the male encourages her by his presence, or when not foraging, guards the spot from intrusion. He is a very jealous husband, and will not permit any of the feathered denizens of the woods to approach, without resenting it in the most determined manner, and inflicting severe punishment. Human interference is greeted with loud and angry cries, and the infuriated bird is with difficulty beaten off.

In Texas, according to Dr. Lincecum, the nest is built of mud, a substance which is rarely utilized in more northern localities. In situations contiguous to houses, rags of calico, cotton thread, and other similar materials, form a very cosy and suitable lining. Such places are chosen on account of the protection against Hawks which they secure. A single brood is annually raised, and but four eggs constitute a setting. In the abdomen of a female which he dissected there were found one hundred and fifty ova, and from this and the preceding datum, he was led to the inference that the natural life of the Jay was thirty years.

When the young birds make their appearance they are welcomed with demonstrations of great joy by the parents. The latter manifest much solicitude for their safety, and attend to their demands with the most sedulous devotion. They watch over them with unwearying vigilance, and actually imperil their own lives when their helpless charges are in danger. Earthworms, caterpillars, moths of various kinds, beetles, grasshoppers, acorns, berries, etc., make a voluminous bill of fare, but they are always carefully chosen to suit the age and condition of life. Both birds are seldom absent together in search of food. When three weeks old, the young quit the nest, and a fortnight later, are able to gain their own living.

In the drawing we have delineated the appearances which the sexes present when they have attained their full dress. The female, which is shown considerably in the background, is duller than her lord and, in the natural state, is somewhat smaller. The mature male is purplish-gray below, with a tendency to whitening on the throat, belly and crissum. This is diversified by a black band across the lower throat, which is continued up the sides of the neck and head to a space behind the crest, and, also, by a black frontlet with a whitish border. The wings and tail are a rich blue, with bars of black. The greater wing-coverts, secondaries and tail feathers, the central excepted, are broadly tipped with unsullied white, and the tail is much rounded. The bill and feet are black, and the iris of the eye of a hazel color. The length is about twelve and a quarter inches, wing five and thirteen-twentieths, and tail five and three-quarters.

The eggs are rounded-oval in contour, obtuse, and pretty nearly equal at both extremities. They are brownish-olive on the ground, in most cases, although some specimens show a decided olive-drab color. A few darker olive-brown spots, however, relieve the monotony of the background. The average size is about 1.16 inches in length, and .85 in width. We have seen some that varied from 1.04 to 1.21 in length, and in breadth from .81 to .89 of an inch.
