Population justification: Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
