Population justification: The global population size has not been quantified. The species is described as uncommon to fairly common and local, but may be overlooked (Stotz et al. 1996, Marantz et al. 2020).
Trend justification: The population trend has not been investigated, but declines are suspected on the basis of logging and fragmentation of forests within the range. Tree cover loss amounts to 8-11% over three generations (13.2 years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Due to its sensitivity to the loss and degradation of its habitat population declines may be steeper than the rate of tree cover loss suggests, though overall declines are not thought to be especially rapid (Aleixo et al. 2023, R. Subira in litt. 2024). Tentatively, declines are here placed in the band 10-19% over three generations.
