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.

Possible
About 20% of wildlife watchers report an Indian Grassbird sighting in Manas National Park on a given day, based on 239 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 95th most-seen of the 377 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report an Indian Grassbird in Manas National Park on a given day, against about 10% in June to February, the lowest months. That is one of Manas National Park's driest months, with about 100 mm of rain against 1070 mm in June.
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.
Yes
Of the 3 parks where we can rate Indian Grassbird sightings, Manas National Park has the highest daily chance: about 20%. Next come Kaziranga National Park (India, under 5%) and Chitwan National Park (Nepal, under 5%).
Same family: Pellorneidae
The closest relatives of the Indian Grassbird that you can see in Manas National Park (family Pellorneidae, Ground Babblers and Allies) are Puff-throated Babbler (about 20%) and Abbott's Babbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indian Grassbird is recorded against all the birds logged in Manas National Park (239 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.
