Subspecies
Geographical variation difficult to interpret, as both migratory and resident populations occur. Strong contrast in India between nominate subspecies and cyanota suggests separate species, but overlap and "leapfrog pattern" of key characters between subspecies renders new arrangement problematic. Dark-barred face pattern of some subspecies appears to be present in all juvenile plumages.
Proposed subspecies orientis (from eastern Java) based on longer wing, but not considered distinct from rubecula; putative subspecies amadoni (from Chanda, in central India) appears indistinguishable from cyanota.
The following 12 subspecies are recognised:
citrina (Latham, 1790) - Himalayas east to north-eastern India and western and northern Myanmar. Non-breeding southern India and Sri Lanka.
cyanota (Jardine & Selby, 1828) - Central and southern India.
gibsonhilli (Deignan, 1950) - Central and south-eastern Myanmar, south-western Thailand. Non-breeding Peninsular Malaysia and Singapore.
innotata Blyth, 1846 - Southern China (southern Yunnan), eastern Myanmar, northern and south-eastern Thailand, north-western and southern Indochina. Non-breeding Peninsular Malaysia.
