Population justification: Partners in Flight placed the esimtate in the band 50,000-499,999 individuals (A. Panjabi in litt. 2008).
Trend justification: Despite its ability to tolerate some habitat degradation and fragmentation, this species is declining owing to habitat loss and, possibly, unsustainable hunting levels (del Hoyo et al. 1994).
