Pink-necked Green Pigeon

Identification

The pink-necked green pigeon is a medium-sized pigeon measuring 25 to 30 cm in length and weighing around 105–160 g. The species exhibits striking sexual dimorphism. Males are particularly distinctive, featuring a grey head, pinkish neck and upper breast, and an orange lower breast. Their backs are olive green with green wings marked by black primaries and a distinctive yellow bar across the wings in flight. The belly is yellowish with grey flanks, and the tail is grey with a black terminal band and chestnut upper coverts. Females are smaller overall, with a yellowish belly, throat and face, and greenish crown and back of the neck. Both sexes have pink or reddish legs and white to pale blue-grey bills. Juveniles resemble females but are greyer above.

Unlike many pigeons in the genus Treron, this species is not particularly vocal, though males produce distinctive tri-syllabic whistling calls ending in a coo. Rasping krrak krrak calls have also been recorded. Birds typically call only in communal roosts and when discovering food sources.

Range & Habitat

The pink-necked green pigeon is a common species throughout Southeast Asia, ranging from southern Myanmar, Thailand, Cambodia, and Vietnam southward through the Malay Peninsula and across the Greater Sundas, Bali, Lombok, Sumbawa, and the Moluccas, extending as far east as the Philippines. The species occupies remarkably varied habitats, from primary and secondary forests to forest edges, coastal mangroves, gardens, plantations, and farmland. It shows a clear preference for open environments and typically occurs at forest edges rather than in dense forest interiors. While most common in lowlands and coastal areas, it ranges up to 300 m in the Philippines, 750 m in Borneo, and 1,200 m in Sulawesi. Local movements occur, likely linked to fruit availability, though the species is generally non-migratory.

The species demonstrates remarkable colonisation ability, being among the first frugivores to establish itself on the Krakatoa islands following the catastrophic 1883 eruption, and subsequently colonising newly emerged Anak Krakatau within 36 years of a major eruption in 1952. It has also recently expanded its range to include Flores.

Behaviour & Diet

The pink-necked green pigeon is primarily a frugivore, with its diet dominated by figs, though it also consumes fruits from Glochidion, Breynia, Vitex, Macaranga, Muntingia, Melastoma, Oncosperma, and Bridelia. Shoots, buds, and seeds are taken only occasionally. Pairs work together to raise their young, laying two eggs in a flimsy twig nest constructed in a tree, shrub, or hedge. Both parents share incubation duties and chick-rearing responsibilities. The species is considered an important disperser of fruit seeds throughout its range.

The pink-necked green pigeon has proven remarkably adaptable to human-modified environments and can thrive in crowded cities provided fruiting trees are present. This flexibility has enabled the species to maintain healthy populations across its range despite extensive habitat conversion.

Best Time & Places to See It

As a non-migratory or locally mobile species, the pink-necked green pigeon can be encountered year-round throughout its Southeast Asian range. However, sightings and activity levels are likely highest during periods of fruit abundance. The species favours open habitats and edges, making it more readily observed than many forest pigeons. Look in gardens, agricultural areas, coastal regions, and forest margins rather than dense interior forest. Communal roosts, particularly in fruiting fig trees, offer excellent viewing opportunities, especially in the early morning and evening hours when birds gather to feed and call.

Photography Tips

The striking sexual dimorphism of this species makes it rewarding to photograph both males and females for comparative images. Males' iridescent pink and orange plumage is particularly photogenic in good light. The yellow bar across the wings visible in flight is a distinctive feature worth capturing. Early morning and late afternoon light will best render the males' subtle but beautiful coloration. Patience near fruiting trees, particularly figs, will reward photographers with natural behavioural shots. Watch for communal roosts at dawn and dusk when birds are vocal and active, offering dynamic composition opportunities.
