The Birds Of South Gloucestershire          Long-eared Owl - asio otus

 

It has been shown under controlled conditions that the Long-eared Owl can catch mice in complete darkness and like some other owls it has asymmetrical ear openings: the left ear opening is higher than the right. This positioning helps the bird to locate prey by sound. The hoot of the male Long-eared Owl can sometimes be heard up to one kilometre or nearly three quarters of a mile away. The word Owl comes from the Middle English  word 'owle' and from the Old English 'ule' and is of imitative origin. 'Otus' has a derisory reference to 'simpleton'. Some historical names for Long-eared Owl include; Horn Coot, Cat Owl and Hornie Hoolet.
