The metallic pigeon (Columba vitiensis) also known as white-throated pigeon, is a medium-sized bird up to 37 cm long, in the family Columbidae.
Columba vitiensis forms a chain of eight living and one extinct subspecies that once extended from Japan to Australia:
The adult has an iridescent purple and green crown, black wing and uppertail coverts, yellowish red iris, yellow bill, red orbital skin, white or grey chin and ear coverts, and purplish feet. It has a dull chestnut or glossed purple green below, depends on subspecies. The nominate form C. v. vitiensis from Fiji has dull underparts, while subspecies C. v. halmaheira has the most iridescent plumage. Both sexes are similar, though females are often duller. The young is duller than adult.
Sexual dimorphism in throat colour is constant in several subspecies; for example, in C. v. vitiensis, males have white throats and cheeks, while females are washed with grey. This difference is noticeable even in juveniles. A pigmented malar spot and line beneath the eye is present in all subspecies except in C. v. castaneiceps.
The Metallic Pigeon is distributed through the islands of Indomalaya, Australasia, and Oceania. It occurs in the Philippines, Indonesia after the Wallace Line (except Sulawesi), Papua New Guinea, the Solomon Islands, Vanuatu, New Caledonia, Fiji, and Samoa. It is also found on several small islands off the northwest coast of Borneo. The species likely reached Vanuatu from New Guinea and from where it spread to other Polynesian islands.
While most subspecies are common within their respective ranges, C. v. halmaheira is considered uncommon on Bougainville and the Bismarck Islands. Similarly, C. v. metallica (Lesser Sundas Metallic Pigeon) is rare throughout its range, with the exception of Timor. The subspecies C. v. godmanae (Lord Howe pigeon), formerly endemic to Australia's Lord Howe Island, has been extinct since approximately 1853.
The species occupies a wide elevational and ecological range, extending from coastal mangroves and sea-level forests to montane forests at altitudes of up to 2,750 meters. While they primarily prefer tropical forests, they exhibit significant habitat adaptability. They are frequently observed in degraded forests and edge habitats, and on smaller islands, they are known to venture close to human settlements.
Rather than being long-distance migrants, these birds are nomadic, engaging in irregular, local movements between islands in search of food. They are typically found singly or in pairs. Their diet is diverse, consisting mainly of various fruits, grains, seeds, and berries. The average lifespan for this species is approximately 3 to 4 years.
Their nesting habits are generally consistent with other members of the family Columbidae, with the female typically laying a clutch of one to two eggs per nesting cycle. Although the species is predominantly arboreal, C. v. halmaheira has been recorded nesting on the ground among thick cover. In its bowing display, the bird moves rather slowly and does not erect its tail.
