第十五期：进化，空调，扭曲 - 鸟喙的这点事儿

喙是鸟类的重要器官。 不同的鸟拥有不同形态的喙，应对的是他们不同的功能。 为什么同样是鸟，在不同种类之间喙的区别这么大？除了吃东西以外，还有其他的功能么？为什么有时候会看到有的鸟的喙长得非常异于常鸟？在本期内容， 我们来说说鸟喙的进化与功能，当然还有一些小知识。 图片来源：晒宁鼻涕（小红书：晒宁鼻涕）栗臀䴓图片来源：Martin Renner 黑顶山雀图片来源：网络 短嘴鸦感谢JackieMei这位朋友给我们的赞赏。 如果您喜欢我们的节目，也请您多多评论，转发给更多喜欢观鸟和自然的朋友。 有任何的意见，建议，或者也想参与到我们的节目中来， 可以直接给我们发邮件。再次感谢各位朋友的收听。 我们下期再见！参考文献Evolution of a multifunctional trait: shared effects of foraging ecology and thermoregulation on beak morphology, with consequences for song evolutionNicholas R.
