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".

Under 5% of wildlife watchers report a Thick-billed Green-Pigeon sighting in Namdapha National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Thick-billed Green-Pigeon in Namdapha National Park on a given day, against under 5% in October to March, the lowest months. June to September have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Thick-billed Green-Pigeon is recorded against all the birds logged in Namdapha National Park (23 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.
