攀禽包括鸟纲中的鹦形目、鹃形目、雨燕目、咬鹃目、夜鹰目、佛法僧目、戴胜目、鴷形目和犀鸟目的鸟类。它们的脚趾多为两个向前,两个向后(对趾型),有利于攀缘树木。攀禽因食性不同,分别活动于有树木的平原、山地 、丘陵或者悬崖、水域附近,其喙也呈现出极大的多样性。常见攀禽包括夜鹰、鹦鹉杜鹃、雨燕、翠鸟啄木鸟等。绝大多数攀禽为留鸟,少数物种为候鸟

杜鹃科Cuculidae

此科鸟类均为中小型树栖鸟。它们的脚短弱,两趾向前两趾向后,为对趾型。它们主要以昆虫为食,特别爱吃多数鸟儿不敢吃的松毛虫松针枯叶蛾和舞毒蛾的幼虫,是森林的卫士。它们一般在树顶浓荫里栖息,对人很警惕。其鸣声又大又响,往往彻夜不停,自古就有“望帝啼鹃”“杜鹃啼血”的故事和传说。

大多数杜鹃科鸟类既不做窝也不孵蛋,但“托儿”有高招:借巢育雏。它们会瞅准空子,在寄生鸟亲鸟离巢的短短几分钟里,产下和寄生鸟蛋色彩无异的蛋。杜鹃蛋的孵化期较短,小杜鹃一出壳,连眼都未睁就会将巢内其他蛋和幼雏推到巢边,驮到背上抛出巢去,独享养父母的抚育;而小杜鹃长大后,却会抛下养父母远走高飞。这一切都是杜鹃的本能,不能按人类道德标准给它们扣上“骗子”“凶手”“忘恩负义”“黑心肠”的各种罪名。值得思考的是:杜鹃借巢育雏的本能是怎样产生和形成的?
