About this species
The western barn owl (Tyto alba) is a species of barn owl native to Europe, southwestern Asia, and Africa. It was formerly considered a subspecies group together with barn owls native to other parts of the world, but this classification was found to be paraphyletic with respect to some other members of the genus.
The plumage on the head and back is a mottled shade of grey or brown; that on the underparts varies from white to brown and is sometimes speckled with dark markings. The facial disc is characteristically large and heart-shaped, with white plumage in most subspecies. This owl does not hoot, but utters an eerie, drawn-out screech.
The western barn owl is nocturnal over most of its range, but in Great Britain, it also hunts by day. Barn owls specialise in hunting animals on the ground, and nearly all of their food consists of small mammals, which they locate by sound, their hearing being very acute. The owls usually mate for life unless one of the pair is killed, whereupon a new pair bond may be formed.

西仓鸮(学名:Tyto alba)或称西方仓鸮,是分布最广的猫头鹰种类,也是所有鸟类中分布最广的之一,属于鸮形目中两科之一的草鸮科。它广布于欧洲和非洲,除了极地、荒漠等外。不同亚种间的体型和颜色差异很大,但体长大多在33至39厘米之间,翼展在80到95厘米之间。头背部的羽毛为斑驳的灰色或棕色,下体呈白色至棕色,有时带暗色斑点。面盘是标志性的心形,大部分亚种为白色。
绝大部分西仓鸮为夜行性动物,但在英国和一些太平洋岛屿,它们也在日间狩猎。西仓鸮擅长猎杀地面上的动物,几乎所有的猎物为小型哺乳动物。它们的听觉十分敏锐,通过听声辩位的方式捕捉猎物。它们为终身配偶制,若配偶被杀,新的配对才可能会形成。繁殖时间视所处地域而定,每窝平均产4只蛋,营巢于空树洞、旧房屋或壁岩洞中。雌鸟负责孵蛋,雄鸟为雌鸟和雏鸟提供食物。当大量小型猎物能被轻易取得时,西仓鸮的数量会快速增长。它们在全球范围被评估为无危物种,但部分地区的一些亚种受威胁的程度较高。
