LC
Chestnut-sided Shrike-vireo Vireolanius melitophrys



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 may be moderately small to large, 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 is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2022); thus it is here placed in the band 20,000-49,999 mature individuals.

Trend justification

The population trend has not been investigated. Tree cover loss is low within the range (2% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species also occurs in selectively logged forests (Brewer 2020); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
