Population justification: The global population size has not been quantified, but the species is described as not uncommon by Konig et al. (1999), and uncommon by Jathar and Rahmani (2006).

Trend justification: This species is capable of tolerating habitat degradation, occurring in even semi-open or cultivated areas, and even around human settlements. Therefore, given the low rate of habitat loss within its range (Tracewski et al. 2016) the species is considered to be stable.
