Population justification:
At the end of the 2013-2014 breeding season, the global population was estimated to be 4,200 individuals, with 3,540 birds on Torishima, 650 birds on the two islands in the East China Sea and 10 birds on Ogasawara Islands. Eda et al. (2012) showed that two populations of Phoebastria albatrus existed about 1,000 years ago and suggested that descendants of each population have segregated breeding colonies on Torishima and on the two islands in the East China Sea. The sequence divergence between the two clades is greater than between other Diomedeidae sister species (Eda and Higuchi 2012). The trend of assortative mating was indicated among birds from the Torishima and the two islands in the East China Sea (Eda et al. 2016).
Trend justification: In 1954, 25 birds (including at least six pairs) were present on Torishima. Given that there are now 609 breeding pairs on Torishima (H. Hasegawa in litt. 2014), the species has undergone an enormous increase since its rediscovery and the onset of conservation efforts.
