Description

The plumage of the blackish oystercatcher is slaty-black with wings and back being rather dark brown. The long bill is blood-red and the legs are white. The sexes are similar in appearance. The blackish oystercatcher is easily overlooked on a rocky shore. Its dark colour blends in with the colour of the rocks on which it walks as it forages, and it does not draw attention to itself. Its presence, however, can easily be detected by its loud and distinctive warning calls. The song of the blackish oystercatcher, when given in duet, consists of an excited chatter of piping whistles. Calls include notes that sound like "pip" and "peeeeyeeee".

Feeding Habits
Blackish Oystercatcher predominantly consume mollusks like mussels and limpets, along with chitons, crustaceans, and some fish. They exhibit foraging behaviors such as hammering and prising on rocky shores, and their diet shifts to mainly mussels in winter on mudflats. Unique dietary items include endangered northern abalone. Blackish Oystercatcher's feeding is adapted to intertidal zones.
Habitat
Blackish Oystercatcher proliferates along coastal environments, particularly favoring rocky shorelines and intertidal zones that comprise rockpools and pebbly beaches. This bird species exhibits a preference for gradually sloping shores rather than steep rocky coasts. During breeding, blackish Oystercatcher is often found on pebble and shell beaches but shifts to interact with shingle shores, rocky outcrops, and mudflats outside the breeding season. Such habitats are favored across broad geographical regions encompassing parts of the South American coastline.
