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.
