Cranes fly past the setting sun near Linum, Germany. The cranes spend the summer in Scandinavia, where they breed. Every fall they migrate south to spend the winter in warmer climes in southern France and Spain. En route the birds take a four to six week break in the German wetlands. Cranes are omnivorous, living on berries, roots, leaves as well as insects and smaller birds and mammals. The marshland near Linum becomes host to up to 80,000 cranes every year.
