Similar Assertions

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.

Freckled Nightjars are more likely to go into energy-saving mode based on how bright the moon is than on how cold it is, which means they might be using the moonlight to hunt instead of just reacting to the temperature.

The moon's light changes how much food night-migrating birds can find, which affects their energy levels during travel.
