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 'uncommon' (Stotz et al. 1996). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 2.5% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
Trend justification
.
Race C. a. aurita occurs in Guyana, east through Suriname to French Guiana and south to northern Brazil (Manaus E to Amapá). C. a. inexpectata occurs in south east Colombia and north west Brazil, south and east along the western bank of Rio Negro. C. a. occidentalis occurs in north east Ecuador and north east Peru (east of Rio Napo). C. a. australis occurs south of Rio Amazon from north east Peru (south to Ucayali) to west Brazil (east to Rio Madeira, south to northern Acre and central Rondônia); population east of Rio Madeira in western Rondônia provisionally placed here.
Inhabits humid lowland forest. Most frequent in well-drained, tall terra firme forest with fairly dense growth of understorey plants; seems to avoid densest thickets, or not especially attracted to them. Generally does not occur in regions with extensive bamboo, and not partial to bamboo where it is present. South of Rio Amazon, may be concentrated in or restricted to blackwater drainages, where appears to replace C. peruviana. Recently recorded at 1300 m in western Guyana.
