Several subspecies have been proposed for the plumage and size variation seen in different geographic populations. The nominate form is from China (Canton), which is also the origin of the introduced population in Hawaii. Subspecies ''formosa'' from Taiwan has been considered as doubtful and indistinguishable from the nominate population. The population in India ''suratensis'' (type locality Surat) and ''ceylonensis'' from Sri Lanka have fine rufous or buff spots on the back. There is a size reduction trend with specimens from southern India being smaller and ''ceylonensis'' may merely be a part of this cline. The lesser and median wing-coverts are also spotted at the tip in buff.<ref name=fbi2>{{cite book|title=The Fauna of British India. Birds.

The population from Hainan Island is placed in ''hainana''. Others like ''vacillans'' (=''chinensis'') and ''forresti'' (= ''tigrina'') and ''edwardi'' (from Chabua = ''suratensis'') have been considered invalid.<ref>{{cite book|title=Check-list of birds of the world.
