陆居权的回答：

鸮又称猫头鹰、枭，是夜行性鸟类，大多数种类几乎专以鼠类为食，是重要的益鸟。由于它们的外貌丑陋，叫声凄厉，给人以恐怖的感觉，因而招致一些人的厌恶，甚至有一些迷信传说，认为它是不吉利的鸟，其实都是不正确的。从它给人们带来的巨大益处来说，应该大力保护才对。 我国常见的种类有红角鸮、雕鸮、鸺鶹（xiu liu）、长耳鸮和短耳鸮。 红角鸮（Otus scops）是一种小型鸮类，比鸽子还小一些，上体褐色，有黑色和黄褐色斑；后头部有黄白色斑，下体淡褐色有暗褐纵纹，头上有两簇小型耳羽。栖于山地、林中深处，平时昼伏夜出，嗜食昆虫。遍布我国东北、河北、陕西、甘肃等地，为留鸟。 雕鸮（Bubo bubo）是大型鸮类，体长约半米，体褐色，有黑斑纹，耳羽甚长，尾短、翼宽；下体有黑纵斑，胸部斑比腹部斑宽大。留居于东北、河北及山西等地。 鸺鶹（Glaucidium cuculoides）是我国南方普遍分布的一种小型鸮类，它的整个上体以棕褐色为主，密布有狭细的棕白色横斑；翅及尾羽黑褐色，在尾羽上有六条鲜明的白色横带，头部不具耳羽，这些特征使它很容易与红角鸮区别开来。鸺鶹是昼夜活动，因而白天在林中也很容易遇到它，为我国南方留鸟。主要以昆虫为食，也吃鼠类及青蛙等。 长耳鸮（Asio otus)上体黄褐色，有密集的黑褐色斑，下体淡色有黑褐色纵斑，耳羽长。栖于低山地带，平原森林中，白天很少活动，黄昏后飞出觅食，以小型兽类和昆虫、小鸟为食，分布于我国东北、西北、新疆等地。对农业有益。 短耳鸮（Asio flammeus）与长耳鸮外形十分相似，但比长耳鸮色较淡，下体淡色有十字形黑褐色纹，耳羽较小。栖于平原、耕地、草原等地，昼间常可见于平原或沼泽地带，平时潜伏于草丛间，夜间觅食；以啮齿类为主，白天以昆虫为食。繁殖于我国北方，越冬时刻遍及全国。对农业有益。 全球的猫头鹰种类名称： Tytonidae: Barn and Grass Owls 草鸮科 Tyto tenebricosa Greater

张亮亮的回答：

猫头鹰，又叫鸮（猫头鹰是它的俗称），属于鸮形目夜行性猛禽，共有180多种。分布在我国的猫头鹰大约有26种，均属于国家二级保护动物。 猫头鹰的大眼睛只能超前看，要向两边看的时候，就必须转动它的头。猫头鹰的脖子又长又柔软，能转动270度。由于是夜间出来捕食的种类，它们的听力十分的敏锐，它的两只耳朵不在同一个水平上，有利于根据地面猎物发出的声音来确定猎物的正确位置。 猫头鹰是现存鸟类种在全世界分布最广的鸟类之一。除了北极地区以外、世界各地都可以见到猫头鹰的踪影。猫头鹰完全依靠捕捉活的动物为食。猎物的大小视猫头鹰的体型大小而定，小到昆虫，大到兔子都有。
