Asio otus
Family: Owls · Status: Ship-assisted · Size: 35–40 cm · Conservation: Least Concern
Widely distributed in North America and Eurasia.
Similar in appearance to Short-eared Owl, but can be separated by strong streaks on underparts that extend down the belly and are accompanied by ventral barring. In flight, fine barring on wing tips (primaries), lack of white trailing edge, and orange irides.
Grasslands, shrublands, open forests, and dense vegetation near open habitats.
Nocturnal; takes long glides while hunting. Has been observed in communal roosts outside the breeding season.
