The heaviest of all oystercatchers, the sooty oystercatcher weighs up to 980 g (2.16 lb), averaging around 819 g (1.806 lb), with females larger and heavier in both subspecies. Males have shorter, thicker bills and females have longer, thinner bills. The 19% average difference in length is the most marked of any oystercatcher species.

Feeding Habits
Sooty Oystercatcher mainly forages during low tide, with diets differing between sexes. Females eat soft prey like fish and jellyfish, while males prefer hard-shelled species like mussels and sea urchins. They exhibit specialized feeding behaviors based on prey type.
Habitat
Sooty Oystercatcher typically resides along coastal environments, favoring rocky shores. Geographically, they inhabit broad coastal regions featuring rocky coastlines, as well as estuaries with mudflats and sandy beaches, predominantly on islands. During the breeding season, sooty Oystercatcher selects habitats such as sand and shingle beaches, often on islands, avoiding mainland shores. The species employs distinct nesting strategies based on habitat. In areas where their range overlaps with similar species, sooty Oystercatcher demonstrates a preference for nesting on rocky shores, whereas their counterparts prefer sandy shores with adjacent mudflats.
