A slim owl, crow-sized, yellow-eyed, long-winged, without a white throat. Upperparts are gray-brown, underparts are heavily streaked and barred with dark brown. Facial disks are rusty, and the ear tufts are long and closely spaced. In flight, they have a buff patch in the upperside of the wing and a dark crescent at the bend of the wing's underside. Voice is a long "hooo," which may be repeated, or doglike barks and hoots, whines and squealing sounds--although they are usually silent on the wintering ground in Missouri.
