Subspecies
Forms a superspecies with Azure Dollarbird (Eurystomus azureus). Sometimes treated as conspecific with Azure Dollarbird (Eurystomus azureus).
Nominate and subspecies calonyx intergrade in areas of southern China and northern Indochina, and intermediate birds from northern Thailand have sometimes been placed in subspecies deignani. Proposed subspecies latouchei from north-eastern China considered inseparable from calonyx; cyanocollis is synonym of nominate, abundus is synonym of calonyx.
Wallacean birds from southern Sulawesi and Lesser Sundas, described as subspecies connectens, appear intermediate between orientalis and pacificus but variable, with some individuals inseparable from latter. In past, birds of north-western Australia occasionally separated as subspecies bravi.
The following 12 subspecies are recognised:
calonyx Sharpe, 1890 - Northern India (Garhwal, northern Assam, northern Cachar) and Nepal to eastern China (north to Manchuria), south-eastern Russian Far East (to lower R Amur) and Japan (Honshu to Kyushu). Winters south to southern Asia and Greater Sundas.
orientalis (Linnaeus, 1766) - North-eastern India (southern Assam), Myanmar and Indochina south to Greater Sundas, Philippines and Ryukyu Is, with single breeding record (probably this race) from Dagasuli in Loloda Is (off north-western Halmahera, northern Moluccas). Winters southern and east to northern Sulawesi and Moluccas.
laetior Sharpe, 1890 - South-western India (Western Ghats southern into Kerala).
irisi Deraniyagala, 1951 - South-central Sri Lanka.
gigas Stresemann, 1913 - Southern Andaman Is.
oberholseri Junge, 1936 - Simeulue I, off north-western Sumatra.
waigiouensis Elliot, DG, 1871 - New Guinea, including Karkar, Bagabag, western Papuan Is, Yapen, Rook, Trobriand Is, D'Entrecasteaux and Louisiade Archipelagos.
crassirostris Sclater, PL, 1869 - Bismarck Archipelago.
solomonensis Sharpe, 1890 - Solomon Is (Bougainville, Buka, Feni, Guadalcanal, Ulawa, Uki and San Cristobal, probably also Nissan I).
pacificus (Latham, 1801) - Lesser Sundas and northern and eastern Australia, probably also southern Sulawesi and Sula Is; southern populations winter north to New Guinea and Wallacea.
cyanocollis Vieillot, 1819 - Himalayas to China, Manchuria and Korea. Winters to Indonesia.
