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.
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).
This population is suspected to be in decline owing to ongoing habitat loss and degradation.
This species's range extends from eastern Colombia through northern Brazil, southern and eastern Venezuela to the Guianas (French Guiana, Guyana, Suriname).
The species chiefly inhabits humid lowland forest, although habitat preferences vary geographically, and in some areas it can also be found in semi-deciduous and gallery forests, palm swamps, cerrado woodland, mature mangroves, clearings with scattered trees and plantations. It is most abundant below 900 m, although it occurs in small numbers at high altitudes, locally to 2400 m in Venezuela. It feeds primarily on arthropods, but also on small vertebrates, taken by gleaning, pecking or probing into bark crevices, dead leaves, clumps of moss or knotholes. It is a regular associate of mixed-species flocks frequenting the mid-levels and subcanopy (Marantz et al. 2003).
