Shanghai, Jiangsu, China.
Considered conspecific with S. brunnea and, especially, S. alphonsiana by some authors. Where range overlaps with that of latter, the two species are sometimes found in mixed flocks in which occasional hybrids reported; see details under S. alphonsiana. Race suffusa poorly marked, perhaps better united with nominate; elisabethae doubtfully distinct from suffusa (exact SW geographical limits of which unclear), and the single type was a specimen in full moult (colour, which varies considerably with wear, an unsatisfactory character for racial diagnosis). Entire Korean population included in race fulvicauda, but those in extreme N possibly belong with mantschurica. Six subspecies currently recognized.
Introduced in Europe#R (Lombardy, in NW Italy).
