Formerly included in the genus Carduelis but more recent studies found greenfinches to be a monophyletic group, genus Chloris which is not sister to other Carduelis species (Sangster et al. 2011).

[edit] Subspecies

There are 6 subspecies[1]:

  • C. s. sinica:
  • Western China (Gansu) to southern Manchuria
  • C. s. chabarowi:
  • C. s. ussuriensis:
  • Eastern Manchuria to southern Ussuriland and Korea
  • C. s. kawarahiba:
  • Kamchatka, Kuril Island, Sakhalin and Hokkaido; winters to Japan
  • C. s. minor:
  • Southern Japan (Honshu, Shikoku and Kyushu) and Korea (Cheju-Do Island)
  • C. s. kittlitzi:
  • Southern Japan (Bonin Islands and Volcano Islands)

[edit] Habitat

Cultivated fields, city parks, gardens and wooded areas.

[edit] Behaviour

[edit] Breeding

Nest is a cup constructed out of grasses and moss and lined with finer grasses and softer vegetation. It is usually placed in a tree, but sometimes a bush. The female lays 2 to 5 eggs which she alone incubates.

[edit] Diet

Mostly seeds including weed and shrub seeds, and sunflower seeds, also rice, buckwheat and other grains. They will also feed on insects, spiders, and other small invertebrates, particularly during the summer breeding season.

[edit] Movements

Partly migratory. Populations in the north move south in September–October and winter at lower altitudes.

[edit] Vocalisations

Song consists of a mixture of chattering and coarse notes given from high perch or in slow display-flight. Call is a distinct, nasal djeeeeee.
