研究发现蜂鸟用柔软的纸币和舌头 来高效吸取花蜜 Study finds hummingbirds use flexible bills and tongues to efficiently suction nectar.

《皇家社会界面议事录》的一项研究表明,蜂鸟有惊人的灵活法案。 A study in the Proceedings of the Royal Society Interface reveals that hummingbirds have surprisingly flexible bills. 研究人员发现,这些鸟类在与舌头协调,以高速抽取花蜜的同时,迅速打开并关闭其部分浮标。 Researchers found that these birds rapidly open and close parts of their bills while coordinating with their tongues to draw nectar at high speeds. 这一发现突出表明了其账单在结合抽吸和机械抽水机制的喂养方面的关键作用。 This discovery highlights the essential role of their bills in feeding, combining both suction and mechanical pumping mechanisms.
