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
This species has a large range, extending from the foothills of the Himalayas (Nepal and Sikkim) from northeast Pakistan and India east to western Nepal, Bangladesh, Bhutan, Myanmar, southern China (southeast Xizang and southern Sichuan south to Yunnan, Guangxi and Hainan), Thailand and northern Indochina, Peninsular Malaysia, Sumatra to Borneo.
DESCRIPTION
The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2006).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. |
