Population justification: The global population was estimated to number c.2,600-3,400 individuals, roughly equivalent to 1,700-2,300 mature individuals, based on records and surveys (BirdLife International 2001). However, this is thought to be an underestimate, as the number in China alone is estimated at c.1,000 mature individuals and could be around 1,500-2,000 mature individuals (Xiaolin Chen et al. in litt. 2012). On this basis, the population is placed in the band for 2,500-9,999 mature individuals, which is probably equivalent to 3,800-15,000 individuals, assuming that mature individuals account for around 2/3 of the population.

Trend justification: Surveys of a breeding population on an offshore island in southern China indicate a decline of 22% over six years (Xiaolin Chen et al. in litt. 2012). There is little additional evidence for a significant decline in this species's population over the last ten years, although overall some decline (<20% over ten years) is suspected to be occurring, owing to on-going loss and degradation of available habitat through reclamation, especially of offshore breeding islands.
