The migration of birds is a complicated process, made even more confusing by the fact that many species migrate at different times and in different directions. But scientists have discovered their migratory routes are deeply tied to natural seasons on Earth and will spring into action when they detect changes in those seasons.

Birds migrate to warmer climates during the winter, but how do they know where to go? A recent study found that birds can detect changes in Earth’s magnetic field. Birds use this information to determine which direction is north and where their food source is located. Read more in detail here: how far do birds migrate.

What do birds use as a compass when they migrate?

A: Birds use the Earths magnetic field as a compass to navigate during migration. They are able to detect changes in the magnetic field, which helps them know when they are moving in the right direction.

Why do most birds migrate at night?

A: Most birds migrate at night because they are able to see better during the day, and they dont need as much sleep. Birds have a different circadian rhythm than humans, so their body clock is set up differently.


Birds migrate to find food and a suitable habitat. They do not know where they are going, but they can sense the changes in their environment and use this information to find a new location. Birds are able to detect these changes by using their sense of smell. Reference: do all birds migrate.
