The Papuan hawk-owl (Uroglaux dimorpha) is a medium-sized, sleek owl with a proportionately small head, long tail, and short, rounded wings. Its white facial disk is small and indistinct, with black streaks, and white eyebrows. It has buff colored upperparts and barred black and brown underparts. Its eyes are bright yellow, and it has a gray to black bill. The male is larger than the female, which is unusual among owls; in most owl species, the female is larger than the male.
