Long-eared Owl

The Long-eared Owl is a medium-sized owl with conspicuous erect ear tufts, a pale tawny facial disc edged in black, and mottled ochre, grey, and dark-brown upperparts. The visible tufts are display feathers rather than the openings used for hearing. Its actual ear slits are large and asymmetrically placed, an arrangement that helps locate sounds above and below the bird. In flight, relatively short broad wings and a squarer tail give it different proportions from the Short-eared Owl. (Wikipedia, Long-eared Owl account)

Long-eared Owls use semi-open landscapes, roosting and nesting in dense stands of trees while hunting across nearby open ground. Small rodents, particularly voles, dominate the diet, although birds and insects are taken when regular prey is scarce or local conditions differ. Instead of constructing a nest, a pair commonly occupies one built by another animal, especially a corvid. The species is not strongly territorial or sedentary, and some populations move or disperse in response to prey availability and seasonal conditions. (Wikipedia, Long-eared Owl account)
