Megascops asio ⁷

A small (7-10 inches) owl, the Eastern Screech-Owl is most easily identified by its size, streaked breast, and ear-like feather tufts. This species has two color morphs, one with gray plumage and the other with rusty-red plumage. Male and female Eastern Screech-Owls are similar to one another in all seasons. The Eastern Screech Owl inhabits much of the eastern United States and southern Canada west to the eastern edge of the Rocky Mountains. This species also occurs in northern Mexico south to the Tropic of Cancer. Eastern Screech-Owls are non-migratory in all parts of their range. Eastern Screech-Owls inhabit a variety of deciduous, evergreen, or mixed woodland habitats. This species may also be found in more built-up areas, and can sometimes be found in large urban parks. Eastern Screech-Owls eat a variety of small animals, such as insects, songbirds, and rodents. Like most owls, the Eastern Screech-Owl hunts almost exclusively at night, making it difficult to observe. This owl may be more visible when it is active at dusk or just before sunrise, and birds roosting in trees may be seen during the day with the aid of binoculars. As its name suggests, the Eastern Screech-Owl produces a high-pitched hooting call which may be used to identify this species at night.
