这是《科学美国人》——60秒科学。我是凯伦·霍普金斯。只需要一分钟！

当你想到鸟类时，你可能会想到它们令人眼花缭乱的羽毛或美妙的歌声。但自达尔文时代以来，科学家们已经发现，鸟类的个体物种不应该同时具备这两个特征：它们要么是单调而有技巧的，要么是只唱一个音符的好看的鸟。

现在一项研究表明，一些鸟类实际上既擅长于视觉表演又擅长于声音表演。这项工作发表在《皇家学会B类学报》上。

鲜艳的羽毛和复杂的歌声是吸引配偶的不同方式。展示得越夸张，鸟类就越容易被注意到。但这些夸张的招牌需要消耗大量的能量来产生。这就是为什么科学家们认为鸟类必须在旋律和外表之间进行选择。

但对中南美洲的一类歌鸟——唐纳鸟的详尽调查显示，没有发现任何权衡。虽然一些唐纳鸟物种确实强调演说而不是外表，比如恰如其分地命名为"单调半斑鸟"的物种，但一些物种，比如山唐纳鸟，既迷人又悦耳动听。而白腹籽鸟则不介意看起来和听起来相当沉闷。

不同的物种可能经历了不同的选择压力，导致它们采取了不同的策略。无论需要什么来吸引潜在配偶的眼睛和/或耳朵。
