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 stable, 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 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.
RANGE DESCRIPTION
Race Anthus richardi richardi breeds in southwestern Siberia and northeastern Kazakhstan east to Lake Baikal; winters mainly southwest Asia, some farther west. A. r. dauricus breeds in Transbaikalia and Yakutia east to Sea of Okhotsk and south to northern Mongolia, Manchuria and northeastern China (NW Heilong-Jiang); winters in southern Asia. A. r. centralasiae breeds in eastern Kazakhstan (Zaysan Basin, eastern Tien Shan) east to western and southern Mongolia, south to northern China (Xinjiang, Qinghai, Gansu, probably also Nei Mongol); winters southern Asia. A. r. ussuriensis breeds in southeastern Russia (lower Amur area, Ussuriland) south to eastern China (S to Sichuan and R Yangtze), probably also Korea; winters southeastern Asia. A. r. sinensis occurs in southeastern China south of River Yangtze.
DESCRIPTION
The global population size has not been quantified, but the species is described as common throughout most of its range (del Hoyo et al. 2004).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. |
