There are 4 subspecies[1]:

  • P. s. sinensis:
  • Central and eastern China (Sichuan and southern Shaanxi) east to Jiangsu, and south to Guangxi, Guangdong and Fujian; also isolated sites in Beijing and Hebei); partially migratory, some moving in winter to central Vietnam, Hainan, and South Korea
  • P. s. hainanus:
  • South China (south-western Guangdong and southern Guangxi); northern Vietnam; Hainan
  • P. s. formosae:
  • P. s. orii:
  • South Ryukyu Islands (Yonaguni and Ishigaki)

Previously recognized P. s. hoyi from Middle Yangtze River Valley (Sichuan, Hubei and Hunan) was described from a juvenile specimen and is a junior synonym of nominate.

Habitat

Open woodland, srub, cultivated areas, orchards, gardens with large shrubs.

Behaviour

Vocalisations
