Northern Slaty Antshrike Thamnophilus punctatus


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 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 this species is described as fairly common to common through much of its wide range (Zimmer and Isler 2003), although the subspecies in Peru and Ecuador are relatively rare, and their habitat is under threat.

Trend justification
The population trend for this species is difficult to determine as anthropogenic processes may be both reducing and increasing local populations (del Hoyo et al. 2003).

Distribution and population

This species has a large range in the Guayana Shield and northern Amazonia, with several apparently disjunct populations that include: along the eastern base of the Andes in western Venezuela and in Colombia; in the the Rio Huallaga drainage of northern Peru; and in the Rio Marañon drainage of northern Peru and southernmost Ecuador.
