Justification:
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). The population trend appears to be increasing, 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 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). For these reasons the species is evaluated as Least Concern.

Geographic Range [top]

Range Description:	This species has a large range, breeding across tundra in much of Canada, Alaska, U.S.A., and parts of the northern U.S.A., and wintering in southern North America, including Mexico. Introduced populations are now resident in much of the U.S.A. south of the normal breeding range, as well as in a number of western European countries. The subspecies asiatica, which occurred in the Bering Sea region, has been extinct since around 1914 (Fuller 2000).
