The Eastern Screech-Owl (Megascops asio) is a small owl that is relatively common in Eastern North America, from Mexico to Canada. This species is native to most wooded environments of its distribution, and more so than any other owl in its range, has adapted well to man-made development, although it frequently avoids detection due to its strictly nocturnal habits.
Two color variations are referred to as “red or rufous morphs” and “gray morphs” by bird watchers and ornithologists. Rusty birds are more common in the southern parts of the range; pairings of the two color variants do occur. While the gray morph provides remarkably effective camouflage amongst the bark of hardwood trees, red morphs may find security in certain pine trees and the colorful leaves of changing deciduous trees.
