Population justification: The global population is estimated at 1,500,000 mature individuals (Partners in Flight 2019).
Trend justification: This species appears to benefit from anthropogenic land-use change (Clark and Mitchell 2020) and the population is thought to be increasing (Meehan et al. 2018).
