Population justification: Partners in Flight estimate the total population to number 50,000-499,999 individuals (A. Panjabi in litt. 2008).

Trend justification: The species is currently common to very common throughout its range. However, its limited range and reliance upon tropical deciduous forests makes it vulnerable to any habitat degradation or destruction (del Hoyo et al. 1994).
