The '''Long-eared Owl''' (''Asio otus'') is a species of [[owl]] which breeds in [[Europe]], [[Asia]], and [[North America]]. This species is a part of the larger grouping of owls known as [[typical owl]]s, family [[Strigidae]], which contains most species of owl. The other grouping of owls are the [[barn owl]]s, family [[Tytonidae]]. |
|||
==Appearance== |
|||
The Long-eared Owl is a medium sized owl, 31-37 cm in length with an 86-98 cm wingspan. It has erect blackish ear-tufts, which are positioned in the center of the head. The female is larger in size and darker in colouration than the male. |
|||
The Long-eared Owl’s brownish feathers are vertically streaked. [[Tarsus (skeleton)|Tarsus]] and toes are entirely feathered. Eye disks are also characteristic in this species. However, the eye disks of ''A. otus'' are darker in color or rusty-orange. This [[nocturnal]] species is perhaps most easily seen perched in a tree in its daytime roost. |
|||
==Behaviour== |
|||
The Long-eared Owl's breeding season is from February to July. This [[bird]] is partially [[bird migration|migratory]], moving south in winter from the northern parts of its temperate range. Its habitat is forest close to open country. |
|||
It nests in trees, often [[coniferous]], using the old stick nests of other [[bird]]s such as [[crow]]s, [[raven]]s and [[magpie]]s and various [[hawk]]s. The average clutch size is 4-6 eggs, and the incubation time averages from 25-30 days. It will readily use artificial nesting baskets. An unusual characteristic of this species is its communal nesting in thickets during the winter months. |
|||
The Long-eared Owl hunts over open country by night. It is very long winged, like the similar [[Short-eared Owl]], and glides slowly on stiff wings when hunting. Its food is mainly [[rodents]], small [[mammal]]s, and [[bird]]s. |
