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 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.

Population justification
The global population size has not been quantified, but the species is described as common or locally common and abundant in some areas in the non-breeding season and during migration (Clement 1999), while national population estimates include: < c.1,000 wintering individuals in China; c.50-1,000 wintering individuals < c.50 individuals on migration in Japan and c.100-10,000 breeding pairs in Russia (Brazil 2009).

Trend justification
This species has undergone a large and statistically significant decrease over the last 40 years in North America (-90.2% decline over 40 years, equating to a -44.1% decline per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher a.
