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 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.

|Population:||Rich et al. (2004) estimated the global population to number 3,400,000 individuals. In Europe, the breeding population is estimated to number 7,500,000-19,000,000 breeding pairs, equating to 22,500,000-57,000,000 individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is 45,900,000-228,000,000 individuals, although further validation of this estimate is needed. National population estimates include: c.10,000-100,000 breeding pairs in China; c.100-100,000 introduced breeding pairs in Taiwan; c.10,000-100,000 breeding pairs in Korea; c.100-10,000 breeding pairs (possibly introduced) in Japan and c.10,000-100,000 breeding pairs in Russia (Brazil 2009).
Trend Justification: This species has had stable population trends over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007) In Europe, trends since 1980 have been stable, based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).
|Current Population Trend:||Stable|
