LONG-EARED OWL—Family Strigidæ.

366. Asio wilsonianus. 15 inches.

This species has unusually long ear tufts, from which it is given its name; the face is brown, the under parts white and buff, with streaks and bars of brownish black; back is brown, with almost black markings; wings and tail brown; barred with black.

Nest.—Usually in trees, frequently using a crow’s nest instead of building for themselves. They are in great disfavor with the crows. They lay from four to seven pure white eggs (1.55 × 1.35).
