Population justification: The population was previously estimated to number 1,000-2,499 individuals, based on an assessment of known records, descriptions of abundance and range size. However, the species is being recorded at an increasing number of localities, suggesting that the population has been underestimated, and it is thought likely to exceed 2,500 individuals (S. David-Rivera in litt. 2011). On this basis, the population is now placed in the band for 2,500-9,999 mature individuals.

Trend justification: The population has not been intensively surveyed, and the species is known to tolerate modified habitats, but remaining forest in its range continues to be cleared and fragmented, suggesting that it is likely to be in a slow and continuing decline.
