Did you know that...?

Like other birds, after the breeding season, Shelducks moult and grown new feathers. During this time, Shelducks are particularly vulnerable as they are unable to fly or dive thus form huge flocks at the coast. Some of the most impressive flocks can reach over 100,000 birds and been seen off the German coast.
