Question

Why do birds fly south for the winter?​

Answer 1

Answer:

Many birds fly south in the winter. Birds that eat nectar or insects will not be able to find food in areas that have cold winters.

To find the food they need, birds will migrate.

Migrating means leaving to find warmer areas.

Birds that migrate usually leave at about the same time each year and fly back home at around the same time each spring!

Answer 2

Answer:

Why do birds migrate? Birds migrate to move from areas of low or decreasing resources to areas of high or increasing resources. The two primary resources being sought are food and nesting locations. ... As winter approaches and the availability of insects and other food drops, the birds move south again.
