| Summary: | Globally, the species is listed as Endangered because the area of occupancy is small (B1) and a decrease in the number of individuals has been inferred (2e). Although the status in Australian waters more closely fits Vulnerable: A2d, on the basis of probable decreases in population over the next three generations (75 years), it is upgraded as per Gärdenfors et al. (1999) to match the global status, because all visiting birds are from an Endangered population. Australian fishing zone Estimate Reliability Extent of occurrence 5,000,000 km 2 low trend stable medium Area of occupancy 5,000 km 2 low trend decreasing medium No. of breeding birds 3,300 medium trend decreasing high No. of sub-populations 1 high Generation time 25 years medium 6 Infraspecific taxa None described.
