How the Moon Helps Night Birds Eat and Fly
The lunar cycle drives migration of a nocturnal bird

Surprising Findings
Up to 100% of birds migrated simultaneously during certain periods.
Complete population-level synchronization is extremely rare in wild animals—most migration is staggered. This level of coordination was unexpected.
Practical Takeaways
Conservation efforts could time habitat protection or light pollution regulations around lunar cycles to support nocturnal migrants.

European nightjars stay up late hunting bugs, and they seem to do it more when the moon is bright—probably because the extra light helps them see their dinner better.
The phases of the moon might help time when night-flying birds migrate together, and all that group movement could spread nutrients and germs in ways that affect entire ecosystems.
European nightjars stay up way longer and hunt more bugs on bright, moonlit nights than on dark ones — it’s like they’re using the moon as a nightlight to help them see their dinner.
European nightjars seem to time their big migration flights with the moon — they all tend to take off together about 11 days after the full moon, like clockwork.
European nightjars don’t stay longer at rest stops just to take advantage of bright moonlit nights—they actually leave about a week after the full moon, following a set schedule instead of waiting for the best lighting conditions.
