Migration
Migration is a form of adaptation. Birds migrate to survive. Learning about migration is one of the best ways to understand the risks that birds and other animals must take in their daily lives - and it's a great way to interpret the changes you can see in the bird life around you.

Arctic terns have the longest migration of all. This means a round trip of up to 35,000 km each year.

Swifts
Swifts need warm weather to provide a constant supply of flying insects, so they spend only about three months in the UK each year.
