LC
Soft-plumaged Petrel Pterodroma mollis

Justification
This species has an extremely 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). The population trend appears to be stable, and hence the species does not 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.

Distribution and population
The Soft-plumaged Petrel breeds on islands in the Southern Hemisphere, nesting on Tristan da Cunha and Gough Island (St Helena to UK), the Prince Edward Islands (South Africa), Crozet Islands (French Southern Territories) and on the Antipodes Islands (New Zealand). It disperses outside the breeding season, reaching eastern South America north to Brazil, South Africa, Australia and New Zealand (del Hoyo et al. 1992).

Population justification
Brooke (2004) estimated the global population to number at least 5,000,000 individuals.

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
This marine species is highly pelagic, rarely approaching land except at colonies. It feeds mostly on cephalopods but will also take crustaceans and fish, which is taken mainly by surface-seizing. Breeding starts in September in colonies on oceanic islands, occupying steep slopes with tussock grass or ferns, usually along the coast but also inland. Pairs nest in long burrows (del Hoyo et al. 1992).
