THE WOOD OR SUMMER DUCK.

The or  (Aix sponsa) represents a group possessing a slender body, moderately long, thin neck, a large crested head, and a short slender bill, which terminates in a hooked and nail-like tip. In these birds the short powerful foot is placed far backward; the narrow, pointed wing has its first and second quill longer than the rest; and the very broad strong tail is composed of sixteen feathers, and rounded at its extremity. The plumage of this species is magnificently coloured, and forms a crest at the back of the head; a small space between the eyes and the base of upper mandible is bare. This beautiful bird has the feathers on the crown of head and the cheeks of glossy dark green; the sides of head and a patch on sides of the neck are purplish green shaded with blue; the crest is golden green, decorated with two narrow white stripes that commence on the brow; the sides of the upper neck and breast are bright reddish brown dotted with white; some of the shoulder-feathers, hinder parts of back, and upper tail-covers, are blackish green; the rest of the shoulder-feathers, the primary quills, and tail, greenish purple, shaded with blue and glossy black; some of the exterior tail-feathers are prolonged, and of an orange hue; the lower tail-covers are brown; the chin, throat, a band on the upper neck, the centre of the breast, and the belly, are white; the sides of the body yellowish grey, marked with black; some of the long feathers on these parts are black edged with white; the eye is bright red; eyelid orange; beak whitish, with reddish base and black tip; the foot is reddish yellow. This species is seventeen inches and a half long and twenty-seven and a half broad; the wing measures eight and a half, and tail four inches. The female is somewhat smaller than her mate, and without an actual crest upon her head; her plumage is deep brownish green on the back, shaded with purple and spotted; the head is greyish green, neck brownish grey, gullet white, breast white spotted with brown, and belly pure white; the eyes are surrounded by a broad white line, which passes from thence as far as the region of the ear. The Summer Duck is a native of America, where it occupies the United States, and thence wanders regularly to the central portions of that continent and to the West Indies; it has also been killed in Great Britain, France, and Germany, but most probably these specimens were not stragglers but birds that had been reared in aviaries. According to Audubon, the flight of the Wood Duck is remarkable for its speed, and the ease and elegance with which it is performed. "It passes," he says, "through the wood, and even among the branches of trees, with as much facility as the Passenger Pigeon, and when removing from some secluded haunt to its breeding-grounds, at the approach of night it shoots over the trees like a meteor, scarcely emitting any sound from its wings." Wilson asserts that these birds seldom fly in parties of more than three or four individuals together; but Audubon expresses his surprise at such a statement from the admired author of "American Ornithology," and assures his readers that he has "seen hundreds in a single flock, and has known fifteen to be killed by a single shot." In disposition the Wood Duck is naturally bold and fearless; but, if molested, soon becomes shy and cautious. When in captivity it is very readily tamed, and exhibits much attachment to those who feed it. In their natural state these birds subsist upon grain, reeds, delicate shoots of plants, worms, snails, and insects, the latter being gleaned from the trees, or snapped at as they float through the air; they will also readily devour small reptiles, and a variety of similar fare. When tame, they can be reared on corn or fish, and in fact will eat almost anything that may be offered them. The period of incubation commences about March, and at this season the parties separate in pairs and commence their search for a convenient breeding-place. For this purpose a squirrel's or Woodpecker's hole is usually selected as affording all that they require, and into this the female at once creeps in order to make the preparations necessary for the
