Transcript of Owl

Barn Owl
The Barn Owl is a pale, long-winged, long-legged owl with a short tail.The Barn Owl measures about 25–50 cm (9.8–20 in) in overall length, with a wingspan of some 75–110 cm (30–43 in). Adult body mass is also variable, ranging from 187 to 800 g (6.6 to 28 oz), the owls closer to the tropics being generally smaller. Tail shape is a way of distinguishing the Barn Owl from true owls when seen in flight, as are the wavering motions and the open dangling feathered legs. The light face with its heart shape and the black eyes give the flying bird an odd and startling appearance, like a flat mask with oversized oblique black eyeslits, the ridge of feathers above the bill somewhat resembling a nose.
Description
About The Barn Owl
The Barn Owl is the most distributed species of owl, and one of the most widespread of all birds. is found almost anywhere in the world except polar and desert regions, Asia north of the Alpide belt, most of Indonesia, and the Pacific islands. She is nocturnal, as is usual for owls, but often becomes active shortly before dusk and can sometimes be seen during the day when relocating from a sleeping place it does not like.
Hunt
This is a bird of open country such as farmland or grassland with some interspersed woodland, usually below 2,000 m ASL but occasionally as high as 3,000 m ASL in the tropics. This owl prefers to hunt along the edges of woods. It has an effortless wavering flight as it quarters pastures or similar hunting grounds. Like most owls, the Barn Owl flies silently; tiny serrations on the leading edges of its flight feathers help to break up the flow of air over its wings, thereby reducing turbulence and the noise that accompanies it.It hunts by flying low and slowly over an area of open ground, hovering over spots that conceal potential prey. They may also use fence posts or other lookouts to ambush prey. The Barn Owl feeds primarily on small vertebrates, particularly rodents. Studies have shown that an individual Barn Owl may eat one or more rodents per night; a nesting pair and their young can eat more than 1,000 rodents per year. Barn Owl threat displays usually include hissing and bill-snapping.
