Justification of Red List Category
This species has a small range, and falls within the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2). However, 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.
The global population size has not been quantified, but the species is described as generally common to abundant (del Hoyo et al. 2005).
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
