Population justification: The global population size has not been quantified, but the species is described as scarce or locally common (del Hoyo et al. 2006).
Trend justification: Much uncertainty. Remote sensing data (Global Forest Watch [2021], using Hansen et al. [2013] data and methods disclosed therein) indicate that on this species' remote breeding grounds, forest loss has occurred at a negligible rate over the past 20 years. In its non-breeding range, forest loss has also been slow (equivalent to 2% over the past 10 years) and as such a continuing decline in mature individuals cannot be inferred. However, there are reports of increasing anthropogenic pressures in its breeding range in response to increasing human and livestock populations (Arun P. Singh in litt. 2022, J. Eaton in litt. 2022), although data from India between 2006-2007 and 2019 suggest there has been no decline (Arun P. Singh in litt. 2022).
