SCREECH OWL
373. Otus asio. 9.5 in.
Two color phases independent of age, sex or season; eyes yellow; has ear tufts. The Screech Owl, or its sub-species, is found throughout the United States, and is one of the most abundant and best known of the family. They are not at all timid, in winter frequently being found in church towers, while on the outskirts of cities and in the country, they reside, at all seasons of the year, in orchards. They remain mated for life, and live in the same tree for years, if not too much disturbed by curious boys. Both adults and the four young are often found in the nest together, and they offer no resistance when they are removed by hand. Their food is almost wholly of insects and rodents.
Notes.—A wavering trill.
Nest.—In holes of trees; eggs white (1.35 × 1.20).
Range.—Resident in U. S. and southern Canada. 373a. Florida Screech Owl (floridanus), is smaller and slightly darker, 373b. Texas Screech Owl (mccalli), is smaller and more heavily barred on the sides.
