名鸟维鸟

鸟是两足、恒温、卵生的脊椎动物，身披羽毛，前肢演化成翅膀，具有坚硬的喙。鸟纲在生物分类学上是脊椎动物亚门下的一个纲。因其身体被羽毛覆盖，中国古代动物学将其统称为羽蟲。
鸟的体型大小不一，最大的鴕鳥體高可達2.5公尺，而最小的吸蜜蜂鳥體長最小僅5公分。目前全世界为人所知的現存鸟类一共有一萬多种，僅中国就记录有1,300多种，其中特有种至少有70幾種。与其他陆生脊椎动物相比，鸟是一个拥有很多独特生理特点的种类。
鸟的食物多种多样，包括花蜜、种子、昆虫、鱼、腐肉、其他的鸟甚至垃圾。大多数的鸟是在日间活动，也有一些鸟是夜间或者黄昏的时候活动（例如夜鷹、猫头鹰等）。许多鸟都会进行长距离迁徙以寻找最佳栖息地（例如北极燕鸥），也有一些鸟大部分时间都在海上度过（例如信天翁）。
