The distributions of the subspecies are as follows (from HBW, since it has more extensive range descriptions than Clements; HBW recognizes an extra subspecies of Asian Emerald Dove, maxima, and an extra subspecies of Pacific Emerald Dove, timorensis, not recognized by Clements):

Asian Emerald Dove Chalcophaps indica

C. i. indica: Indian Subcontinent (S from Himalayan foothills), S China (SE Sichuan, Yunnan, Guangxi, Hainan), Taiwan and S Ryukyu Is, and S through SE Asia and Philippines to Greater and Lesser Sundas (E to Alor), Sulawesi, Moluccas (except SE part) and W Papuan Is.
C. i. robinsoni: Sri Lanka.
C. i. natalis: Christmas I (S of Java).
C. i. minima: islands of Numfor, Biak and Mios Num (Geelvink Bay), in NW New Guinea.
C. i. augusta: Nicobar Is.
C. i. maxima: Andaman Is.

Pacific Emerald Dove Chalcophaps longirostris

C. l. rogersi: coastal New Guinea (from Astrolabe Bay in N and Hall Sound in S) E to Trobriand Is, D’Entrecasteaux Archipelago and Louisiade Archipelago, then on to E Australia (S to Victoria); also Lord Howe I and Norfolk I, where perhaps introduced.
C. l. longirostris: N Australia in N Western Australia (Kimberley region) and N Northern Territory.
C. l. sandwichensis: Santa Cruz Is, Banks Is, Vanuatu and New Caledonia.
C. l. timorensis: E Lesser Sundas (from Wetar, Timor and Roti) E to S & SE Moluccas (Banda Is, Tayandu Is, Kai Is) and Tanimbar Is.

The two emerald dove species differ in head coloration (Asian has a white forehead/supercilium and [in males] gray crown, while Pacific has a pretty much solid brown head).

Please update your records to species accordingly.
