Taxonomy and Classification
The common emerald dove's taxonomy has undergone significant changes over the years. In 1743, English naturalist George Edwards included a picture and description of the species in his book A Natural History of Uncommon Birds, using the English name "Green Wing'd Dove".
Edwards' drawing was made from a live bird at a merchant's home in Rotherhithe, near London, and he was told the dove had come from the East Indies. Carl Linnaeus, a Swedish naturalist, updated his Systema Naturae in 1758, placing the common emerald dove with other pigeons in the genus Columba.

Linnaeus coined the binomial name Columba indica and cited Edwards' work, noting that the specific epithet indica is Latin for "Indian" and refers to the East Indies. Today, the species is placed in the genus Chalcophaps, introduced by English ornithologist John Gould in 1843.
There are six recognized subspecies of the common emerald dove. Here are the details:
- C. i. indica (Linnaeus, 1758) – India to south China, Malaysia, Philippines, Indonesian and west Papuan islands
- C. i. robinsoni Baker, ECS, 1928 – Sri Lanka
- C. i. maxima Hartert, 1931 – Andaman Islands
- C. i. augusta Bonaparte, 1855 – Nicobar Islands
- C. i. natalis Lister, 1889 – Christmas Island (Indian Ocean)
- C. i. minima Hartert, 1931 – Numfor, Biak and Mios Num islands (off north New Guinea)
Physical Characteristics and Behavior
The common emerald dove is a stocky, medium-sized pigeon, typically 23-27 cm in length. The back and wings are bright emerald green.

Behaviour and Ecology
Emerald doves are quite terrestrial, often searching for fallen fruit on the ground and spending little time in trees except when roosting.
They eat seeds and fruits of a wide variety of plants and are generally tame and approachable.
Their flight is fast and direct, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general.
In fact, they're particularly good weavers when flying through forests, exposing a buff underwing and a chestnut colour of their flight feathers.
The call of the Emerald dove is a low soft moaning cooing consisting of about six to seven coos, starting quietly and rising.
Distribution and Habitat
The Common Emerald Dove is a bird that thrives in tropical forests.
It's also commonly found in dense wet woodlands, farms, and mangroves.
In fact, it builds its nest in a tree up to five metres high, using sticks.
The nest is a scant stick nest, which means it's not very elaborate, but it gets the job done.
The dove lays two cream-coloured eggs, which is a typical clutch size for this species.
It appreciates the cover of dense foliage, which makes it a great fit for the tropical forests and mangroves it calls home.
