Justification
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

Population
Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Black-capped siskin

The black-capped siskin (Spinus atriceps) is a species of finch in the Fringillidae family. It is found in Guatemala and Mexico. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.

Phylogeny[edit]

It has been obtained by Antonio Arnaiz-Villena et al.[2][3][4]

Identification[edit]

Spinus/Carduelis atriceps has been defined as a gray wash with a black cap finch.[5] However, other green morphs have been also identified with Spinus atriceps, but they apparently are Spinus/Carduelis pinus green morphs.[5]
