BLACK OYSTERCATCHER


Haematopus bachmani


Description:

Unlike the American Oystercatcher, the Black Oystercatcher prefers rocky coasts, where it feeds on a variety of marine life, except oysters! Actually, they will eat oysters, but not to the extent they eat other marine life, such as invertebrates, especially mussels, worms, echinoderms; also fish, crabs, barnacles and limpets. Especially those that cling to rocks below the high-tide line.


Appearance:

Entirely black plumage. Long, thick, bright orange bill. Yellow eye surrounded by orange orbital ring. Pale pink legs. Sexes similar. Juveniles have browner plumage and a dark bill tip. 17 to 17.5 inches in length.


Habitat:

Rocky shorelines.


Nesting:

2-3 olive-buff colored eggs with brown-black blotches. The eggs have a 24-29 day incubation period. Fledging occurs at 35+ days. The nest is a shallow ground depression or hollow, amoung pebbles, on a beach.


Observed Locations:

  • Cabrillo National Monument tidepools, Point Loma
  • Zuniga Jetty, San Diego Bay
