2025年10月9日发表在《科学》上的一项新研究证实,大小蝙蝠、欧洲最大的蝙蝠、猎杀和吃候鸟在飞行中。 A new study published in Science on October 9, 2025, confirms that the greater noctule bat, Europe’s largest bat, hunts and eats migrating songbirds mid-flight. 研究人员使用生物记录标签观察到蝙蝠上升到近 1,200 米，然后高速潜水，使用回声定位捕捉欧洲知更鸟等鸟类。 Using biologging tags, researchers observed the bats ascending to nearly 1,200 meters before diving at high speed to catch birds like the European robin using echolocation. 一次有记录的袭击包括鸟在静默前发出21次求救呼叫,然后在飞行时喂食23分钟。 One recorded attack included 21 distress calls from the bird before silence, followed by 23 minutes of feeding while flying. 在狩猎地点下面发现的鸟类翼碎片上的咬痕表明,蝙蝠摘除翅膀以降低体重。 Bite marks on bird wing fragments found beneath hunting sites suggest bats remove wings to reduce weight. 以及DNA和音频证据支持这些发现,揭示了该物种开发迁徙鸟类的能力,尽管这些鸟类的体积和敏捷度很大。 DNA and audio evidence support the findings, revealing the species’ ability to exploit migrating birds despite their size and agility. 这一发现为了解这只濒危蝙蝠的觅食行为提供了罕见的洞察力。 The discovery offers rare insight into the foraging behavior of this endangered bat.
