Eastern Screech-Owl

The Eastern screech-owl (Otus asio) is a small owl that ranges from six to nine inches in height. Mostly active at night, Eastern screech-owls prey on birds and small mammals as well as insects, frogs, lizards, and tadpoles. These true owls have excellent camouflage skills — depending on their unique coloration, they find the perfect matching tree cavity to roost.

Found throughout eastern North America from Canada to Mexico, this short and stocky species has a misleading name. It doesn't actually screech but makes a descending tremolo call. (Listen to the Eastern screech-owl’s call via Cornell’s Macauley Library.)
