Chandragiri Pass, central Nepal

.

Geographically outlying race angkanensis distinguished by its strong flame-red breast (3); slightly broader russet-chestnut back (“cape”) than the next best-marked taxon (1); and in varying degrees by the strength of its yellow rump, shortness of its bill, brightness of its vent, etc., but in each of these it is matched by certain other taxa. Race horsfieldi intergrades with nominate in W Nepal. In India, proposed race griseiceps (from Ghoom, near Darjeeling) considered inseparable from nominate, and ripleyi (from Mawryngkneng, in Khasi Hills) synonymized with koelzi. Nine subspecies recognized.
