Population justification: Baker et al. (2014) estimated 39,995 breeding pairs on the Bounty Islands, which represents 99% of the global population; this is equivalent to 79,990 mature individuals, or roughly 110,000 total individuals.

Trend justification: In 1998, the population on the Bounty Islands (99% total) was estimated to be 30,750 breeding pairs (Clark et al. 1998, A. M. Booth in litt. 1999) compared to the estimate in 1978 of 76,000 breeding pairs (Robertson and van Tets 1982). Although census methods differed between years making comparisons difficult, island-wide ground counts of breeding birds during incubation on Proclamation Island resulted in totals that declined 14% from 3065 in 1997 to 2634 in 2004; a count of breeding albatrosses over part of the island in 2011 indicated a further decline of 13% between 2004 and 2011 and an overall decrease of 30% 1997-2011 (Sagar et al. 2015). In addition, in 2010 and 2013, aerial surveys of all breeding sites in the Bounty Islands and ground counts on Proclamation Island provided an estimation of 31,786 and 39,995 breeding pairs in 2010 and 2013, respectively. Nevertheless, due to methodological differences, it is not possible to combine all data sets and further studies using the same methodology is necessary to assess the population trend.
