Justification of Red List Category
Although this species has a small range, it is not believed to 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 is moderately small to large, and hence does not 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.
In the early 1990s, the population was estimated to number 14,000-25,000 breeding pairs (del Hoyo et al. 2006), or 28,000-50,000 mature individuals. The population is suspected stable and therefore is likely to have remained in the band 20,000-49,999 mature individuals.
The population is suspected to be stable in the absence of evidence for any current declines or substantial threats.
