Alternative names: Wilson's Shearwater; Mother Carey's Chickens
- Oceanites oceanicus
Identification
Length 7.25" (18 cm), wingspan 16-18" (41-46 cm). Dark blackish brown except for bold U-shaped white rump patch that extends onto flanks, pale carpal bars and underwings.

It breeds on the Antarctic coastlines and nearby islands such as the South Shetland Islands as well as in southern Chile. Common migrant in the North Atlantic Ocean.
Taxonomy
Subspecies
Two subspecies are recognized[1]:
- oceanicus is a mainly temperate species mostly limited to the southern hemisphere
