Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 2.7% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
Trend justification
.
Race X. o. perplexus occurs in western Amazonia, south of Amazon, in northeastern Peru (east from lower Rio Ucayali, possibly from Rio Huallaga) and western Brazil (east at least to Rio Tefé, probably to Rio Purús, and south to southeastern Acre); recorded also in extreme northeastern Bolivia (Pando). Race X. o. ocellatus is patchily distributed in Amazonian Brazil, south of Amazon, from Rio Purús east to left bank of lower Rio Tapajós.
Chiefly evergreen forest. At most sites occurs in tall terra firme forest, but at some mostly near rivers or swamps (várzea at some sites) or in forests associated with sandy soils. Frequents primarily interior of mature forest, less often in disturbed forest, second growth (including younger growth), and forest edge. Patchy distribution possibly related to habitat preferences that are poorly known, and perhaps geographically variable. Chiefly Amazonian lowlands, mostly below 500 m.
