Sound localization in owls. Eurasian eagle-owl in Poland. Most owls are nocturnal or crepuscular birds of prey. Because they hunt at night, they must rely on non-visual senses. Experiments by Roger Payne [1] have shown that owls are sensitive to the sounds made by their prey, not the heat or the smell. In fact, the sound cues are both necessary ...

The Eurasian eagle-owl is one of the most widely distributed of all owl species, although it is far less wide-ranging than the barn owl, the short-eared owl (Asio flammeus) and long-eared owl and lacks the circumpolar range of boreal species such as great grey owl, boreal owl and northern hawk owl (Surnia ulula).
Long-eared owl. The long-eared owl ( Asio otus ), also known as the northern long-eared owl[ 3] or, more informally, as the lesser horned owl or cat owl, [ 4] is a medium-sized species of owl with an extensive breeding range.

[ 6] Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. [ 2] It has a number of unique adaptations to its habitat and ...
This fossil is from a taxon similar in size to the great horned owl (B. virginianus) or the great grey owl (S. nebulosa). [ 11 ] The Sinclair owl ( Bubo sinclairi ) from Late Pleistocene California may have been a paleosubspecies of the great horned owl, [ 12 ] while the roughly contemporary Bubo insularis of the central and eastern ...
