This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Geographic Range [top]

Range Description: The Black-winged Petrel breeds in the south-west Pacific, from Lord Howe Island (Australia) and eastern Australia in the west, New Caledonia in the north, the Chatham Islands (New Zealand) in the south and Austral Islands (French Polynesia) in the east. Outside the breeding season it migrates to the north and east Macific, being common in the north-west Pacific in July - November, and particularly abundant between the Hawaiian Islands (USA) and Peru1.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is marine and highly pelagic, avoiding land except during breeding. Little is known about its diet, but it is known to include cephalopods and prawns which it catches mainly by surface-seizing and dipping, but also pattering. It has often been recorded feeding in association with other Procellariiformes. It breeds in colonies on oceanic islands, usually making burrows on high ground inland amongst scrub or tussock grass (del Hoyo et al. 1992).
Systems: Terrestrial; Marine
