Population justification: The total population is estimated to number fewer than 5,000 individuals (F. Hawkins in litt. 2003), roughly equivalent to 3,300 mature individuals.

Trend justification: The population is suspected to be declining at an unquantified rate, owing to limited habitat loss (F. Hawkins in litt. 2003).
