Population justification: This is not a particularly rare bird at sea, and the total population runs into thousands, if not tens of thousands. Based on this judgement, the population is placed in the range 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: Observations suggest that the population may be increasing.
