Population justification: The number of mature individuals was estimated to be fewer than 50 until 1998 (C. Barbraud in litt. 2013), but Rains et al. (2011) estimated the population at c. 170 birds in total, including 80 mature individuals, with c. 26 pairs breeding annually. Between 2001 and 2007 there were c. 24-31 pairs breeding annually (Rivalan et al. 2010), and in 2014 the breeding population has reached 46 pairs (unpublished CNRS Chizé data from 2014 submitted to ACAP).
Trend justification: It is believed to have suffered severe declines in the 1970s, and so, over the past three generations (c.82 years), it has probably declined overall. However, the population increased between 1983-2009 (ACAP unpubl. data, Inchausti and Weimerskirch 2001, Rivalan et al. 2010). On average, adult survival is just over 97%, the highest ever found for an albatross (Cuthbert et al. 2004, Rivalan et al. 2010), and juvenile survival has also been reported to be very high (up to 70%), and this in part may explain the recent gradual growth of this population (Weimerskirch et al. 1997). However, there has been a recent decline in breeding success in this species, in parallel with a continuous decrease of the Indian Yellow-nosed Albatross population (Thalassarche carteri) on Amsterdam Island (Weimerskirch 2004), and D. amsterdamensis may now be stabilising (H. Weimerskirch in litt. 2016).
