Taxonomic note
Pionites leucogaster, P. xanthomerius and P. xanthurus (del Hoyo and Collar 2014) were previously lumped as P. leucogaster following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species is described as fairly common to common in undisturbed areas (Stotz et al. 1996, Collar et al. 2020).

Trend justification: The population trend has not been quantified, but the species is assessed as being in slow decline as a consequence of habitat loss and potentially hunting and trapping. Large tracts of forest within the range remain pristine and at low risk; over three generations (14.4 years) tree cover loss amounts to 3% (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Despite its apparent preference for edges and openings, the species is not tolerant of habitat degradation, secondary growth or agropastoral land (Collar et al. 2020). The impact of trapping on the population size has not been quantified. Overall however, it is tentatively assumed that population declines do not exceed 10% over three generations.
