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 reception of her eggs, while her faithful spouse keeps watch outside. About May, or in some localities a month later, the eggs, from seven to twelve in number, are deposited; they are small, oval, and have a smooth white or yellowish shell. As soon as all the eggs are laid, the female covers them with down, spreading it thickly over them whenever she quits her charge. No sooner is the mother burdened with family cares than, as is the case with some other species, she is deserted by her hitherto devoted mate, who joins his male companions and roams with them over neighbouring pieces of water until the close of the moulting season. The period of incubation lasts about twenty-five days. "If," says Audubon, "the nest of the Wood Duck is placed immediately over the water, the young, the moment they are hatched, scramble to the mouth of the hole, launch into the air with their little wings and feet spread out, and drop into their favourite element; but whenever their birthplace is at some distance from it, the mother carries them to it one by one in her bill, holding them so as not to injure their tender frames. On several occasions, however, when the hole was thirty, forty, or more yards from a pool or other piece of water, I observed the mother suffered the young to fall on the grasses and dried leaves beneath the trees, and afterwards led them to the nearest edge of the next pool or creek. At this early age the young answer to their parent's call with a mellow 'Pee, pee, pee,' often and rapidly repeated. The call of the mother at such time is soft, low,
