The thick-billed green pigeon (Treron curvirostra) is a species of bird in the family Columbidae. The thick-billed green pigeon was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other doves and pigeons in the genus Columba and coined the binomial name Columba curvirostra. Gmelin based his description on the "Hook-billed Pigeon" from the "island of Tanna in the South Seas" that had been described and illustrated in 1783 by the English ornithologist John Latham. Latham was mistaken in believing that his specimen had come from the island of Tanna in the New Hebrides. The type locality was designated as the Malay Peninsula by Harry C. Oberholser in 1912. The thick-billed green pigeon is now placed with around 30 other green pigeons in the genus Treron that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from the Ancient Greek trērōn meaning "pigeon" or "dove". The specific epithet curvirostra combines the Latin curvus meaning "curved" with -rostris meaning "billed".

With luck
About 10% of wildlife watchers report a Thick-billed Green-Pigeon sighting in Bako National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 66th most-seen of the 70 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Thick-billed Green-Pigeon sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

Of the 18 parks where we can rate Thick-billed Green-Pigeon sightings, Bako National Park ranks 11th at about 10%. The best odds are in Khao Luang National Park (Thailand, about 50%), Cat Tien National Park (Vietnam, about 40%) and Khao Yai National Park (Thailand, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Thick-billed Green-Pigeon is recorded against all the birds logged in Bako National Park (10 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.
