Population justification: The population is estimated to number fewer than 10,000 individuals, and so is placed in the band 2,500-9,999 individuals (R. Schlatter in litt. 2002). This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: The population is suspected to be in decline owing to a lack of suitable habitat.
