Population justification: The overall population of the species probably does not exceed 10,000 pairs (i.e. 20,000 mature individuals) and 30,000 individuals. It is thus placed in the band 10,000-19,999 mature individuals, and thought to number 20,000-30,000 individuals in total.

Trend justification: There are no recent data, however the species is thought to be declining, mainly due to nest predation by introduced predators and open cast mining activities. Marine surveys in the eastern tropical Pacific from 1988-2000 estimated a 35% reduction between the periods 1988-1990 and 1998-2000 (Balance et al. 2002).
