Why do some birds migrate at night instead of daytime?
AnimalsBirds
Quick Answer
Night migration can reduce overheating, avoid many predators, and let birds use stars, the Moon, and Earth’s magnetic field for navigation. It also frees daytime for feeding.
The Full Story
Many birds, especially smaller songbirds, migrate at night. Cooler temperatures help reduce dehydration and overheating, and the darkness can lower the risk from diurnal predators like hawks. Night flying also leaves the day available for feeding and resting. Birds navigate using a combination of cues, including stars, polarized light at dusk and dawn, and magnetic sensing. This is a sophisticated solution to the problem of long-distance travel.
Key Facts
1.Night migration can reduce heat stress
2.It may lower predation risk
3.Birds use multiple navigation cues
