On the Atlantic coast the Long-eared Owl occurs in more or less abundance from Nova Scotia to Florida. It is found in the vicinity of Halifax, according to Mr. Downes, and about Calais according to Mr. Boardman, though not abundantly in either region. In Western Maine, and in the rest of New England, it is more common. It has been known to breed at least as far south as Maryland, Mr. W. M. McLean finding it in Rockville. Mr. C. N. Holden, Jr., during his residence at Sherman, in Wyoming Territory, met with a single specimen of this bird. A number of Magpies were in the same bush, but did not seem either to molest or to be afraid of it. The food of this bird consists chiefly of small quadrupeds, insects, and, to some extent, of small birds of various kinds. Audubon mentions finding the stomach of one stuffed with feathers, hair, and bones. The Long-eared Owl appears to nest for the most part in trees, and also frequently to make use of the nests of other birds, such as Crows, Hawks, or Herons. Occasionally, however, they construct nests for themselves. Audubon speaks of finding such a one near the Juniata River, in Pennsylvania. This was composed of green twigs with the leaflets adhering, and lined with fresh grass and sheep’s wool, but without feathers. Mr. Kennicott sent me from Illinois an egg of this bird, that had been taken from a nest on the ground; and, according to Richardson, in the fur regions it sometimes lays its eggs in that manner, at other times in the deserted nests of other birds, on low bushes. Mr. Hutchins speaks of its depositing them as early as April. Richardson received one found in May; and another nest was observed, in the same neighborhood, which contained three eggs on the 5th of July. Wilson speaks of this Owl as having been abundant in his day in the vicinity of Philadelphia, and of six or seven having been found in a single tree. He also mentions it as there breeding among the branches of tall trees, and in one particular instance as having taken possession of the nest of a Qua Bird (_Nyctiardea gardeni_), where Wilson found it sitting on four eggs, while one of the Herons had her own nest on the same tree. Audubon states that it usually accommodates itself by making use of the abandoned nests of other birds, whether these are built high or low. It also makes use of the fissures of rocks, or builds on the ground. As this Owl is known to breed early in April, and as numerous instances are given of their eggs being taken in July, it is probable they have two broods in a season. Mr. J. S. Brandigee, of Berlin, Conn., found a nest early in April, in a hemlock-tree, situated in a thick dark evergreen woods. The nest was flat, made of coarse sticks, and contained four fresh eggs when the parent was shot.
