Bird migration is perhaps one of the most fascinating phenomena in nature. Each year, billions of birds migrate across the earth from their wintering grounds to their breeding grounds. And back again. Nearly all these birds prefer to migrate over land. There is no food for them over the open sea, whereas on the border of water and land there is a lot of food for many species.
The main migratory routes are therefore also concentrated along the coasts of the continents. One of those 'main highways' for birds runs along the west coast of Europe and Africa, the East Atlantic migratory route. It runs from Eastern Canada and Siberia in the far north, to the southernmost tip of Africa. It is estimated that more than 90 million birds use this route every year.
