Fur from 1,665 bats shows turbine-hit species migrated both north and south
Summary
Biologists examined fur from 1,665 migratory bats to trace their movements like a travel diary. The two species most often killed at wind turbines were moving both north and south each autumn, rather than only south.
Details
Biologists analyzed fur samples from 1,665 migratory bats, using them as a kind of travel diary to trace the animals’ movements. The data were linked to the bats’ migration routes and to the risk wind turbines pose to them.
The findings show that the two bat species most often killed in collisions with wind turbines migrated both north and south during each autumn. This challenges the notion that their seasonal movement is exclusively southward.
The available information does not identify the two species or provide further details about where the samples were collected. The study nevertheless used fur from a large number of migratory bats to track the directions of their movements.
NEXORA AI — Why it matters
The findings indicate that understanding turbine-related bat deaths requires tracking movements in both northward and southward directions.
