Population justification: The population size is estimated to be below 1,000 birds based on analyses of available records. It is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: Although there is very little information available, the one monitored colony appears to be stable; thus, the remainder of the population is also suspected to be stable.
