Some subspecies (e.g. buruensis and amboinensis), may represent separate species. Proposed island subspecies ultramontanus (described from Aru Is) and, off south-eastern New Guinea, propinquus (D'Entrecastaux Archipelago) and dejectus (Louisiade Archipelago) overlap so much in measurements and pattern with mainland carbonarius that all are synonymized with carbonarius . Likewise manumeten (described from Manusela, on Seram) is subsumed in amboinensis.
The following 12 subspecies are recognised:
morotensis Vaurie, 1946 - Morotai, off northern Halmahera (northern Moluccas).
atrocaeruleus Gray, GR, 1861 - Halmahera, Bacan, and West Papuan Is (Kofiau I).
buruensis Hartert, 1919 - Buru I, in south-western Moluccas.
carbonarius Bonaparte, 1850 - Lowland New Guinea and satellite islands (including Boigu, Dauan and Saibai, in northern Torres Strait), and Aru Is.
laemostictus Sclater, PL, 1877 - Southern Bismarck Archipelago (Umboi and New Britain).
meeki Rothschild & Hartert, 1903 - Southern Solomon Is (Guadalcanal).
longirostris Ramsay, EP, 1882 - Southern Solomon Is (San Cristobal).
baileyi Mathews, 1912 - North-western Australia (northern Kimberley Division, Bathurst I, Melville I, and northern Arnhem Land).
atrabectus Schodde & Mason, IJ, 1999 - North-eastern Australia (Cape York Peninsula and north-eastern coast of Queensland south to Burdekin R); may migrate to Torres Strait and south-central New Guinea.
acteatus Gould, 1843 - Coastal eastern Australia from Burdekin R area southern in Queensland (inland to Great Divide) to north-eastern New South Wales (rarely breeding south of 31° south); migrates to north-eastern Australia, islands in Torres Strait and south-central New Guinea.
bracteatus (Gould, 1842) - Eastern Australia (Burdekin R., Queensland to south coast of NSW).
