Song & Call Comparison
Barred Owl
Song: who-cooks-for-you, who-cooks-for-you-all — eight rhythmic hoots.
Calls: cackles, screams and pair duets.
Eastern Screech-Owl
Song: a descending tremulous whinny, plus a long monotone trill.
Calls: soft barks and trills between pairs.
Range & Seasonal Presence
The Barred Owl owns mature eastern woodlands and river-bottom forests, and has spread through the Northwest in recent decades. Wooded suburbs with big trees suit it well.
The Eastern Screech-Owl lives east of the Rockies anywhere trees and cavities exist — including small town parks and backyards. It is the owl most likely to use a backyard nest box.
Feeder Behavior & Favorite Foods
- Barred Owl: hunts rodents, birds, frogs and crayfish — it may stoop on birds and squirrels at busy feeders at dusk.
- Eastern Screech-Owl: hunts large insects, mice and small songbirds; a nest box is the best way to host one.
- Nest boxes: a screech-owl box 10–30 feet up on a tree trunk gets used; Barred Owls need huge cavities and rarely take boxes.
- Window strikes: both occasionally hunt feeder birds at dawn — place feeders within 3 feet of windows or beyond 30 feet.
Temperament & Flock Behavior
Barred Owls are bold and curious — they answer imitated hoots, hunt at dusk and even in daylight, and tolerate people in wooded suburbs.
Eastern Screech-Owls are strictly nocturnal and secretive by day, roosting in cavities or tight against a trunk — but at night a singing male may sit right over the patio.
