|Site Of Nest:
|Breeds on coastal and inland marshes.
Winters mostly on estuaries and beaches.
Insects, fish, offal and carrion.
Breeding adults are unmistakable with their complete black hoods,
drooping red beaks and, above all, broad, rounded, pure white wings.
The non breeding adult is similar but the hood is reduced to an
extensive dusky "bandit" mask through the eye.
