Justification of Red List category
This species has an extremely 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very 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.
Population justification
The population is estimated to number fewer than 20,000 individuals by Wetlands International, and so is placed in the band 10,000-19,999 individuals here. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification
The overall population trend is suspected to be decreasing, although some populations may be stable and others have unknown trends (Wetlands International 2006).
