Justification of Red List category
This species is classified as Least Concern. It 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). The population size is extremely 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). Despite the fact that the population trend appears to be decreasing, the decline is currently thought to be part of a longer-term fluctuation following previous increases. Should new evidence suggest that it is continuing to decline the species would warrant uplisting to Near Threatened.

Population size: 1370000-1620000

Population trend: Decreasing

Extent of occurrence (breeding/resident): 7,180,000 km2

Country endemic: No
