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 Kaziranga National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 230th most-seen of the 323 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 an Indian Grassbird in Kaziranga National Park on a given day, against under 5% in August to April, the lowest months. That is one of Kaziranga National Park's wettest months, with about 340 mm of rain against 10 mm in December. June and July have too few records to rate.
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.
2nd of 3
Of the 3 parks where we can rate Indian Grassbird sightings, Kaziranga National Park ranks 2nd at under 5%. The best odds are in Manas National Park (India, about 20%).
Same family: Pellorneidae
The closest relatives of the Indian Grassbird that you can see in Kaziranga National Park (family Pellorneidae, Ground Babblers and Allies) are Puff-throated Babbler (about 10%) 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 Kaziranga National Park (30 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.
