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 →

Rare
Under 5% of wildlife watchers report a Wedge-tailed Green-Pigeon sighting in Namdapha National Park on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 181st most-seen of the 298 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and October–December
In those months about 10% of wildlife watchers report a Wedge-tailed Green-Pigeon in Namdapha National Park on a given day, against under 5% in January to April, the lowest months. Those are among Namdapha National Park's driest months, with about 150 mm of rain a month against 660 mm in July. June to September have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Wedge-tailed Green-Pigeon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 10
Of the 10 parks where we can rate Wedge-tailed Green-Pigeon sightings, Namdapha National Park ranks 5th at under 5%. The best odds are in Manas National Park (India, about 20%), Royal Manas National Park (Bhutan, about 10%) and Doi Inthanon National Park (Thailand, about 10%).
Same genus: Treron
The closest relatives of the Wedge-tailed Green-Pigeon that you can see in Namdapha National Park (genus Treron, Green-Pigeons) are Pin-tailed Green-Pigeon (about 30%) and Ashy-headed Green-Pigeon (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wedge-tailed Green-Pigeon is recorded against all the birds logged in Namdapha National Park (45 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.
