A new study confirms Europe’s largest bat hunts and eats migrating songbirds mid-flight.
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.
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.
One recorded attack included 21 distress calls from the bird before silence, followed by 23 minutes of feeding while flying.
Bite marks on bird wing fragments found beneath hunting sites suggest bats remove wings to reduce weight.
DNA and audio evidence support the findings, revealing the species’ ability to exploit migrating birds despite their size and agility.
The discovery offers rare insight into the foraging behavior of this endangered bat.
