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.

With luck
About 10% of wildlife watchers report a Large Niltava sighting in Namdapha National Park on a given day, based on 127 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 114th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February and March
In those months about 20% of wildlife watchers report a Large Niltava in Namdapha National Park on a given day, against under 5% in April–May and November, the lowest months. Those are among Namdapha National Park's driest months, with about 110 mm of rain a month against 660 mm in July. June to September have too few records to rate.
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.
3rd of 6
Of the 6 parks where we can rate Large Niltava sightings, Namdapha National Park ranks 3rd at about 10%. The best odds are in Kerinci Seblat National Park (Indonesia, about 40%) and Doi Inthanon National Park (Thailand, about 30%).
GBIF citizen-science records
It is estimated from how often the Large Niltava is recorded against all the birds logged in Namdapha National Park (127 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.
