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 Kaeng Krachan National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 222nd most-seen of the 360 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.
December
In that month about 10% of wildlife watchers report a Wedge-tailed Green-Pigeon in Kaeng Krachan National Park on a given day, against under 5% in January to November, the lowest months. That is one of Kaeng Krachan National Park's driest months, with about 30 mm of rain against 260 mm in September.
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.
7th of 10
Of the 10 parks where we can rate Wedge-tailed Green-Pigeon sightings, Kaeng Krachan National Park ranks 7th 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%).
GBIF citizen-science records
It is estimated from how often the Wedge-tailed Green-Pigeon is recorded against all the birds logged in Kaeng Krachan National Park (122 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.
