Population justification: Partners in Flight estimate the total population to number 5,000,000-50,000,000 individuals (A. Panjabi in litt. 2008).

Trend justification: This species's population is suspected to be stable owing to its nomadic nature and ability to thrive in a wide range of open habitats (del Hoyo et al. 2004).
