LC
Chestnut-backed Antshrike Thamnophilus palliatus



Justification

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). The population trend appears to be stable, and hence the species does not 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 this species is described as locally fairly common in at least parts of its wide range (Zimmer and Isler 2003).

Trend justification
This species is adapted to disturbed and secondary habitats (del Hoyo et al. 2003) and its population is suspected to be stable.

Distribution and population

This species has a large range in two disjunct areas: coastal eastern Brazil; and coastal north-east Brazil through southern Amazonia to the Andes of central and southern Peru and northern Bolivia.
