The Indian grassbird (Graminicola bengalensis) is a passerine bird in the family Pellorneidae. It was formerly placed in the Old World warbler family, Sylviidae, and the Old World babbler family, Timaliidae. The species is also known as the rufous-rumped grassbird.
It occurs in tall emergent vegetation in or bordering freshwater swamps or along banks of rivers in the lowlands of Bangladesh, northern India, Bhutan and the Chitwan National Park of Nepal. It is threatened by habitat loss.
The Sukla Phanta Wildlife Reserve in Nepal represents the western limit of its distribution. Collar, N. J., Robson, C.

Rare
Under 5% of wildlife watchers report an Indian Grassbird sighting in Chitwan National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 260th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report an Indian Grassbird in Chitwan National Park on a given day, against under 5% in March to January, the lowest months. That is one of Chitwan National Park's driest months, with about 30 mm of rain against 660 mm in July.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Indian Grassbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Indian Grassbird sightings, Chitwan National Park ranks 3rd at under 5%. The best odds are in Manas National Park (India, about 20%) and Kaziranga National Park (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Indian Grassbird is recorded against all the birds logged in Chitwan National Park (28 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.
