Range and Habitat

Eastern Screech-Owl: Common in east North America from east Montana and the Great Lakes to the Gulf of Mexico, south to Tamaulipas in northeast Mexico; also found from south Ontario to Florida. Preferred habitats include mixed woodlands, deciduous forests, parklands, wooded suburban areas, riparian woods along streams and wetlands, mature orchards, meadows, and fields.

Breeding and Nesting

Eastern Screech-Owl Gray Morph: Two to eight white eggs are laid on natural sawdust on the floor of a natural tree cavity or abandoned woodpecker hole, usually 6 to 20 feet above the ground; readily nests in suitable boxes. Incubation takes about 26 days and is done mostly by the female.

Foraging and Feeding

Eastern Screech-Owl Gray Morph: Feeds on mice, rats, chipmunks, squirrels, shrews, bats, and moles. Searches for prey while in flight, rather than from a perch.

Vocalization
