LC
Spot-tailed Antwren Herpsilochmus sticturus



Justification

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 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, density descriptions range from uncommon to fairly common (Stotz et al. 1996, Zimmer and Isler 2020).

Trend justification
Tree cover loss is negligible within the range (1% over ten years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.

Distribution and population

The species occurs from east Venezuela through Guyana, Suriname and French Guiana to adjacent north Brazil.

Ecology

It is found in humid and seasonally flooded lowland forests (Zimmer and Isler 2020).
