The pin-tailed green pigeon or pin-tailed pigeon (Treron apicauda) is a species of bird in the family Columbidae native to Southeast Asia. It has also been referred to by the former names Columba longicauda, Vinago apicauda, and Sphenocerus apicaudus in earlier ornithological literature.
The pin-tailed green pigeon is a medium-sized dove, with an average weight of 185-255 grams. Males are 32-36 cm and females are typically 28 cm. It is yellow-green overall, with darker green wing-coverts and scapulars and black outer secondaries and primaries. The males have a golden breast with pinkish hues. The central tail feathers are a bluish-grey and the undertail-coverts a chestnut colour. The orbital ring is blue, as is the bill, with a lighter green or yellow tip. The legs and feet are a bright reddish-pink. The females are a duller yellow, with much shorter central tail feathers and dull undertail-coverts.
The song is described as a soft whistling ku-koo, which is usually paired. The pin-tailed green pigeon also lets out a high pitched doo! call. While in flight, feathers produce a whirring sound. The pin-tailed green pigeon is found in Bangladesh... Wikipedia →

It is the 36th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Pin-tailed Green-Pigeon is recorded against all the birds logged in Namdapha National Park (381 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.
