Black Oystercatcher
Haematopus bachmani
- tidak umum
- 40 km/h
- Risiko rendah
Pacific Coast specialist that pries limpets off wave-pounded rocks. Looks like a goth in a high-vis vest.
- Populasi
- ~8,900–11,000 individuals rangewide (~10,000 breeding birds)
- Habitat
- Rocky intertidal shorelines — sea islets, jetties, breakwaters, and gravel/cobble beaches free of tall vegetation — where it forages on mussel- and barnacle-covered rocks exposed at low tide
- Fakta menarik
- Because it feeds almost exclusively on rocky-shore shellfish, the Black Oystercatcher is treated by biologists as a keystone indicator species for the health of the Pacific intertidal ecosystem.
- Sebaran
- Pacific coast of North America, from the Aleutian Islands and southern Alaska south through British Columbia, Washington, Oregon, and California to Baja California, Mexico; largely year-round resident with only short-distance post-breeding movement
- Makanan
- Marine intertidal invertebrates — chiefly mussels and limpets, also chitons, barnacles, crabs, sea urchins, isopods, and marine worms — pried or hammered open with its strong, laterally flattened bill
