The Black oystercatcher is easily recognized with its black plumage, long, strait, laterally compressed, orange-red bill with a yellow tip, orange-red eye ring, yellow iris, and pale pink legs. These birds are restricted to rocky coastal shorelines where they feed in the intertidal zone.
They are an uncommon to fairly common resident on rocky shores and sand/gravel beaches along the entire coast. Along the sandy central coast, they are present only as an occasional dispersing or wandering individual, typically on jetties.
