Population justification: This species is poorly known and its population size has not been quantified, though has been described as uncommon to fairly common (B. Beehler in litt. 1994, D. Gibbs in litt. 1994, G. Dutson pers. obs 1997).

Trend justification: There are no data on population trends. Remote sensing data (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein) indicate that forest loss is slow but ongoing: in the three generations (21.6 years) to 2023, 2-3% of forest cover was lost within the range, and since 2017 the rate appears to have accelerated (to a rate equivalent to c.4% in three generations). Given much of this species' range lies above elevations affected by logging however, it is not clear whether this is driving population declines. Trends in area of habitat between 1998 and 2020 have remained stable overall (calculated by sRedList [2023], using underlying data from Jung et al. [2020]) and remaining forest appears to have high intactness (Grantham et al. 2020). The population trend is therefore considered unknown.
