Population justification: The population size of this species is difficult to estimate because it is easily overlooked outside of the breeding season. An analysis of detailed accounts in BirdLife International (2001) tentatively suggests that total population may number fewer than 10,000 individuals, and so it is placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: A rapid and on-going decline is suspected, owing to the many active and continuing threats impacting the population.
