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 <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). 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 (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is described as uncommon to rare and occurring at low densities (Stotz et al. 1996, Marantz et al. 2021).
Trend justification
The population is feared to be declining as a consequence of habitat loss. The species is described as sensitive to habitat modification; despite some tolerance of selectively cut forest is it not found in young secondary stands (Marantz et al. 2021).Tree cover loss is low within the range, amounting to 3% over three generations (14.8 years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Given the species' sensitivity to forest degradation, population declines may be steeper than the rate of tree cover loss suggests; precautionarily, they are here placed in the band 1-9% over three generations.
The species occurs in the lowlands of east Venezuela through the Guianan Shield south to the Rio Amazonas in Brazil.
This species is mainly found in "terra firme", gallery or seasonally flooded forests, occasionally also in dry and savanna forests (Marantz et al. 2021). It is usually confined to the interior of mature and primary forest; it avoids young secondary growth, but does occur in some older secondary habitats, edge and selectively cut forest (Marantz et al. 2021). Its diet generally consists of small arthropods, with small vertebrates occasionally taken when available. Breeding is poorly known, probably occurring during the dry season; it has been speculated that only one egg is laid and that the species has a low breeding success (del Hoyo et al. 2003).
The species is threatened by forest loss through logging activities and the expansion of the agricultural frontier.
