Population justification: The global population size has not been quantified, but evidence suggests that it is moderately common within suitable habitat.
Trend justification: Although no quantitative data is available, suitable forest in the Western Ghats is being cleared (del Hoyo et al. 2007), hence the species is suspected to be declining.
