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). While a provisional suspected population size has been supplied that suggested the population may be close to 1,000 mature individuals, appraisal of the extent of the range and frequency of observation (especially in the eastern half of the range where there appear few if any threats) indicates that this is very unlikely, hence the population size is not thought to approach thresholds for listing as threatened. Reported range contraction and reductions in the western half of the range indicate the need for improved monitoring of this low-density species, and there is a clear need for a plausible global population estimate based on targeted surveys from key parts of the range. With the greatest likelihood being that the population size is not small, and much of the range apparently unaffected by significant threats to the species, it is assessed as Least Concern.
