Population justification: Ground counts between 1999-2003 revealed c.5,300 occupied sites (Robertson et al. 2003), and further counts in 2007 and 2010 gave similar figures (5,247 and 5,245 occupied sites, respectively) (Robertson in litt. 2008, Fraser et al. 2011). This gives a total estimated global population of c.11,000 mature individuals, roughly equating to c.16,000 individuals in total.

Trend justification: Counts in recent years (1999, 2000 and 2001) and aerial photographs from 1973, 1974 and 1991 suggest that the population is stable, and is expected to remain stable in the near future (Croxall and Gales 1998, Robertson et al. 2003, C. J. R. Robertson in litt. 2008, ACAP 2010).
