Bats use the evening sky's polarization pattern for orientation
Date:7/23/2014

etic field.

The researchers caught 70 female mouse-eared bats in a cave in North-eastern Bulgaria. During dusk they exposed half of the bats to a polarization direction which was shifted 90 degrees from the natural spectrum. The other half of the animals was placed in similar experimental boxes but with a natural polarization direction. Long after nightfall the bats were brought to two different sites some 20 kilometres away from their home roost. There they were released after the scientists equipped them with tiny radio transmitters to follow their flight trajectories on their way back to the cave. Those animals that experienced a 90 degrees shifted polarization pattern at sunset, vanished in a direction which deviated about 90 degrees from the control group. With this simple experiment the researchers showed for the first time that bats can use the polarization pattern of the evening sky to calibrate their inner compass for orientation. The precise mechanism however, is still unknown so far. "Further behavioural and physiological studies are necessary to understand this fascinating new sensory capability", says Stefan Greif, lead author of this study.
