Migration - the regular movement of birds and other creatures from one part of the world to another and back again - is one of the wonders of the natural world.
Why do birds do it? Where do they go? What hazards do they face along the way? These, and similar questions, are all answered here.
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.
