Population justification: Partners in Flight estimated the population to number fewer than 50,000 mature individuals (Partners in Flight 2019), thus it is placed in the band 20,000-49,999 mature individuals here.

Trend justification: The population trend is uncertain; although substantial areas of habitat have been lost to tourist development, much remains intact and the species seems to adjust well to secondary habitats (Brewer and de Juana 2017).
