LC
Peruvian Sheartail Thaumastura cora



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, but this species is described as locally common (Stotz et al. 1996, Clark 2020).

Trend justification
The species' tolerance of anthropogenic and disturbed habitats suggests it is not currently at risk. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable. In Chile it has been expanding its range since the 1970s (Clark 2020).

Distribution and population

This species occurs in coastal Peru, as well as extreme southern Ecuador and northern Chile.

Ecology

It occurs in a variety of arid vegetation, including in converted habitats (Clark 2020).
