Long-Eared Owl Asio otus LEOW L 15in

Uncommon deep inside forest. Melts into the trees— you know they are there, watching you try to find them. Nocturnal, coming out when pitch-black, rarely before. Away from breeding grounds, roosts are usually communal, sometimes with several birds in one tree. Sits upright and slim (camouflage posture). Whitewash or pellets are usually easier to spot than the bird. Easily flushed, the wings are heard hitting branches as it flies to another tree. A much closer look will often reveal more birds, still sitting. Gives a wide array of hoots, barks, and squeals that are easy to confuse with GHOW. ID: Superficially similar to SEOW. LEOW has longer ear tufts and orange face with black lines through eye and more extensive white in between. Breast barred as well as streaked and much darker—easiest difference to see in flight (daytime). Other differences in flight are more rounded wings, shorter tail, and finely barred outer primaries that lack contrast and dark tip of SEOW. Both species give wing-clapping displays. GHOW is much larger but very similar when flying away in dense woods.
