The long-eared owl (Asio otus) is a medium-sized owl of the family Strigidae, and found in the woodlands throughout much of the Northern Hemisphere.


The long-eared owl is about 12–16 inches long, with a wingspan of 34–39 inches, and weighs between 6.3–15.3 ounces. Females are larger than males. The upper plumage is a yellow rust brown to grayish-brown (females are somewhat darker), mottled with black spots and stripes. Chest and belly are a pale yellow to cream, and bearing dark vertical stripes. The facial disk is a light buff-brown to rufous-brown, with a light greyish "V" mark centered between the yellow-orange eyes, and extending downwards on either side of the beak. The brown ear tufts are set more in towards the center of the face, directly over the eyes; their length sets it immediately apart from the similar short-eared owl, with which it shares much of its range.
