The wedge-tailed green pigeon or Kokla green pigeon (Treron sphenurus) is a species of bird in the family Columbidae. It is greenish yellow with a wedge shaped tail. The crown is tinged with orange-rufous with a variable amount of maroon on the back and scapular feathers in males. This is absent in females due to the wedge-tailed green pigeon's sexually dimorphic plumage, typical of green pigeons.
It is found in the Indian subcontinent and Southeast Asia. It ranges across Bangladesh, Bhutan, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Thailand, Tibet and Vietnam. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
Five subspecies are accepted: Treron sphenurus sphenurus (Vigors, NA, 1832) — mountains of Kashmir and along the Himalaya to southwestern China, Myanmar, northern Thailand, and Laos Treron sphenurus delacouri Biswas, B, 1950 — mountains of central Vietnam
Treron sphenurus robinsoni (Ogilvie-Grant, WR, 1906) — mountains of the Malayan Peninsula Treron sphenurus etorques (Salvadori, AT, 1879) — mountains of Sumatra Treron sphenurus korthalsi (Bonaparte, CLJL... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Wedge-tailed Green-Pigeon is recorded against all the birds logged in Royal Manas National Park (85 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
