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".

Rare
Under 5% of wildlife watchers report a Thick-billed Green-Pigeon sighting in Kolkata on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 209th most-seen of the 247 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Thick-billed Green-Pigeon in Kolkata on a given day, so our monthly data shows no clear season.
Between 1 and 4 am
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.
Among the best
Of the 6 cities where we can rate Thick-billed Green-Pigeon sightings, Kolkata ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Kuala Lumpur (Malaysia, under 5%), Singapore (Singapore, under 5%) and Tamluk (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Thick-billed Green-Pigeon is recorded against all the birds logged in Kolkata (22 verified sightings), 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.
