THE BIRDS OF SOUTH GLOUCESTERSHIRE

 

LONG-EARED OWL – Asio otus

 

As with all reports of rare and scarce birds they are subject to ratification by the respective rarities committees

 

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.
