Population justification: The total population is estimated at 130,000-140,000 mature individuals, based on estimates of 26,000 breeding pairs on the Bounty Islands in 2011 and 41,000 pairs on the Antipodes Islands in 2011 (J. Hiscock in litt. 2012). Based on the assumption that mature individuals account for around 2/3 of the total population, there are estimated to be c.195,000-210,000 individuals.
Trend justification: The Bounty Islands population declined 76% during 1978-1998, but census methods were variable. The Antipodes population declined by c.50% during 1978-1995, and there have been further decreases since (G. A. Taylor in litt. 1999, Taylor 2000, D. Houston in litt. 2008). Based on this information, a very rapid decline is estimated to have occurred over the last three generations. However, recent surveys indicate that the rate of decline may be slower than this (J. Hiscock in litt. 2012).
