Bolivian Slaty Antshrike Thamnophilus sticturus


Justification of Red List Category
This species has a very 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 is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds 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 locally fairly common throughout its small range (del Hoyo et al. 2003).

Trend justification
This species's habitats are under pressure from logging; however, selective logging may increase local densities (del Hoyo et al. 2003), thus an overall trend is difficult to determine.

Distribution and population

This species has a large range in central and eastern Bolivia, and adjacent Brazil and northern Paraguay.
