The Oystercatcher's World
Black Oystercatchers prey on shellfish in the wave zone, especially mussels and limpets. The waves cause mussels to open often, making them easier to eat. The Black Oystercatcher nests on ledges just off shore, and its eggs and young suffer far less predation by mammals. Contrary to their name, oystercatchers rarely eat oysters.
