The large niltava (Niltava grandis) is a species of bird in the Old world flycatcher family Muscicapidae. It is found in Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Thailand and Vietnam. Its natural habitat is subtropical or tropical montane forests.
The large niltava was formally described in 1842 by the English zoologist Edward Blyth based on specimens collected in Darjeeling, India. He coined the binomial name Chaïtaris grandis. The large niltava is now placed with six other niltavas in the genus Niltava that was introduced in 1837 by the English naturalist Brian Hodgson.

Rare
Under 5% of wildlife watchers report a Large Niltava sighting in Manas National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 326th most-seen of the 377 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Large Niltava in Manas National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Large Niltava sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
6th of 6
Of the 6 parks where we can rate Large Niltava sightings, Manas National Park ranks 6th at under 5%. The best odds are in Kerinci Seblat National Park (Indonesia, about 40%), Doi Inthanon National Park (Thailand, about 30%) and Namdapha National Park (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Niltava is recorded against all the birds logged in Manas National Park (11 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.
