Bats 'tricked' into flying into buildings 蝙蝠“上当”撞上建筑物

一项最新科学研究发现，那些有大面积玻璃或镜子外观的现代建筑对蝙蝠来说是“潜在的危险”。科学家呼吁人们对该状况进行持续性监测，特别是在蝙蝠大量聚集的地区中。请听报道。

Bats have a remarkable ability to fly at high speeds in the dark while avoiding obstacles. Yet the number of injured or dead bats found near buildings prompted scientists to investigate the risks.

Experiments and observations of bats in the wild suggest glass windows and mirrored buildings create a blind spot for the flying mammals because of the way these surfaces reflect sound.

Bats make calls and listen to the returning echoes to build up a sonic map of their surroundings. Smooth, vertical structures seem to trick bats into thinking the way ahead is clear, increasing the chances of collision.

Researchers from the Max Planck Institute for Ornithology in Germany say more monitoring is needed to assess the impact particularly in key habitats.
