The long-eared owl is medium-sized, smaller in size than a wood pigeon. It often looks long and thin, with head feathers (known as ear tufts even though they are not ears) which it raises when alarmed. It is buff-brown with darker brown streaks, and deep orange eyes. It is nocturnal and secretive, so unlikely to be seen other than on migration (when birds may turn up on coasts at any time of day) or when leaving or returning to a communal roost site in winter.
