Population and distribution.
The Black Oystercatcher inhabits rocky tidal areas along the West Coast from Baja, California to Alaska. Black Oystercatchers are elusive "Western shorebirds", as they hide among rocks and dunes until the tide ebbs half way out, so they can forage for food, using their chisel-like bills to force open the shells of bivalves.
These oystercatchers are wary birds that incubate 2-3 eggs on the bare sand, in little depressions, surrounded by low plants.
