Population justification: Surveys suggest that this species is fairly common in its preferred habitat (P. Davidar in litt. 2016). A total of 119 birds were recorded in a survey carried out in 1993-94 (Davidar et al. 1996), and over 36 recorded in a rapid survey in 2007 (Pande et al. 2007). 

Trend justification: Evidence of increasing human population pressure and development within the species's range suggests that slow declines are likely to be occurring.
