红隼Falcotinnunculus|奇妙的鸟类

隼形目,隼科

体长:约35厘米;体重:200~300克

主要以昆虫为食,也捕食小型哺乳动物和鸟类。它们善于突然袭击,从高空折起双翅直扑猎物,用嘴打击猎物后脑,在对方受伤、丧失逃生能力时,再高速冲过去抓走猎物,这个过程是一套高精度的攻击和特技飞行表演。它们每窝产2~3枚蛋,从孵化到幼鸟习飞,亲鸟要辛苦忙碌2个月。

鸱鸮科Strigidae

在我国有30余种,被统称为“猫头鹰”,均为国家二级保护动物。它们是“捕鼠专业户”:头可左右各转动180°,观察范围极广;眼无环状肌,不能收缩转动,视网膜圆锥细胞,只有圆柱细胞,所以白天睁一只眼闭一只眼,夜里却可以明察秋毫,看清老鼠的活动;有一对长耳孔,且高低不同,能通过声音准确判断老鼠活动的位置;周身的羽毛又轻又软,飞行时毫无声息,老鼠往往是刚发现“敌情”,就已落入它们的利爪和勾嘴之下。它们会把杀死的老鼠囫囵吞下,等消化完以后才将不能利用的毛、骨从嘴里吐出,所以在其栖息地周围往往有一些褐色的“食团”,那就是老鼠被食后的残渣。猫头鹰在繁殖时才成对活动,树洞、墙洞、岩穴都可以垫一点干草做窝。雌鸟负责抱孵,雄鸟负责警戒。由于人们的不了解,再加上猫头鹰的奇特的模样、夜行习性以及令人感到凄切的夜间鸣叫,过去常被人将它和灾难联系在一起
