The great barbet (Psilopogon virens) is an Asian barbet native to the Indian sub-continent and Southeast Asia, where it inhabits forests up to 3,000 m (9,800 ft) altitude. It has been listed as Least Concern on the IUCN Red List since 2004 because of its wide distribution.
Bucco virens was the scientific name proposed by Pieter Boddaert in 1783 for a great barbet that had been described by Georges-Louis Leclerc, Comte de Buffon in 1781 based on a specimen collected in China. It was illustrated in a hand-coloured plate engraved by François-Nicolas Martinet.
It was placed in the genus Megalaima proposed by George Robert Gray in 1842 who suggested to use this name instead of Bucco. In the 19th and 20th centuries, the following great barbet zoological specimens were described:
Megalaema marshallorum proposed by Robert Swinhoe in 1870 was based on a great barbet from the Himalayas. Megalaima virens magnifica proposed by E. C. Stuart Baker in 1926 was a male barbet from Machi, Manipur. Megalaima virens clamator proposed by Ernst Mayr in 1941 was a bird collected in northern Myanmar.

Rare
Under 5% of wildlife watchers report a Great Barbet sighting in Dehradun on a given day, based on 85 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Great Barbet in Dehradun on a given day, against under 5% in June to April, the lowest months. That is one of Dehradun's driest months, with about 45 mm of rain against 370 mm in July.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Great Barbet sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
6th of 10
Of the 10 cities where we can rate Great Barbet sightings, Dehradun ranks 6th at under 5%. The best odds are in Guiyang (China, about 30%), Kathmandu (Nepal, about 20%) and Guangzhou (China, about 20%).
Same genus: Psilopogon
The closest relatives of the Great Barbet that you can see in Dehradun (genus Psilopogon, Typical Asian Barbets) are Brown-headed Barbet (about 50%) and Coppersmith Barbet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Barbet is recorded against all the birds logged in Dehradun (85 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.
