Population justification: The population size has not been quantified, but the species is described as rare, though possibly under-recorded. Based on the number of observations within its large range (see eBird 2022), it is considered unlikely that the population is small.
Trend justification: The species is reported to have declined over large parts of its range, particularly in Argentina (Winkler and Christie 2020). The main driver of the decline is thought to be the clearance and conversion of woodland (Winkler and Christie 2020).
Within the range, tree cover is lost at a rate of up to 14% over three generations (10.8 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species' strict dependence on trees, including standing deadwood for nesting, suggests that population declines may be steeper than the rate of tree cover loss alone. Declines are therefore here tentatively placed in the band 20-29% over three generations.
