Eastern screech-owls are 6.3 to 9.8 inches long with wingspans of about 18.9 to 24 inches. They are about 6 inches tall and weigh about 130-220 grams (about 4.6-7.8 ounces).

The eastern screech-owl is found in North America. It lives east of the Rocky Mountains in the United States, with small populations in eastern Canada and Mexico.

Eastern screech-owls can be found in wooded areas that are near water, including neighborhoods and parks. They can also be found in trees around orchards, marshes, meadows and fields. They tend to avoid dense forests with thick patches of trees, where larger owls often live.

Eastern screech-owls are carnivores. They eat mammals, birds, earthworms, insects, crayfish, tadpoles, frogs and lizards. They fly down from trees to capture prey but rarely hover when hunting. They also help control small mammal populations — they can easily eat more than 1,000 mice in one year!

At the Smithsonian’s National Zoo, eastern screech-owls eat frozen-thawed mice. They don’t receive live prey.

Eastern screech-owls are nocturnal — they are highly active at night (and more often heard than seen).

Eastern screech-owls are mostly solitary. They are only in pairs during the breeding season. These owls do not migrate. They stay within their home range throughout the winter, leaving only during severe weather in search of food. Eastern screech-owls’ unique feather patterns help camouflage them in the tree bark. When threatened, they will stretch their body and tighten their feathers to look like a branch.

To attract a mate, a male will call to a female while swiveling his head and body. He may also wink his eyes slowly. If he’s successful, the birds will touch bills and clean each other's feathers. Eastern screech-owls mate for life and often reuse the same nest sites year after year.

They nest in natural tree cavities or old woodpecker holes. They will also use nest boxes or nest behind loose boards on abandoned buildings or barns. Females lay three to four eggs. Males help during nesting by bringing food to the female while she cares for the eggs and young.
