What a surprising behavior !
🦇Greater noctules (𝘕𝘺𝘤𝘵𝘢𝘭𝘶𝘴 𝘭𝘢𝘴𝘪𝘰𝘱𝘵𝘦𝘳𝘶𝘴) soar above 400 meters, using echolocation to chase and snatch nocturnal migratory passerines mid-flight—unlocking a high-altitude feast most predators can’t reach.

Greater noctule bats prey on and consume passerines in flight
Despite billions of passerines seasonally migrating during the night at high altitudes, only three bat species have been found to consistently tap into this rich prey resource. However, it remains unk...
