The Indian grassbird 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.
Region
Ganges–Brahmaputra floodplains and Himalayan Terai
Typical Environment
Occurs patchily from the Terai of Nepal through northern and northeastern India to adjacent Bangladesh, chiefly in extensive, seasonally inundated grasslands. It favors tall Saccharum and Imperata grasslands, reedbeds, and edges of marshes along large rivers. The species relies on a mosaic of mature tall grass and early-successional regrowth often maintained by flooding or controlled burning. It avoids dense forest and open farmland, persisting where large, unfragmented grass tracts remain.

Also called the rufous-rumped grassbird, this skulking passerine inhabits dense, tall riverine grasslands and is easily overlooked despite its loud song. It often perches atop grass stems to sing, especially in early morning, but otherwise keeps low and hidden. Its fortunes are closely tied to the maintenance of floodplain grasslands and early post-fire regrowth.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats, low over grass
Social Behavior
Typically found singly or in pairs, maintaining territories within extensive grassland blocks. Nests are placed low within grass tussocks; both sexes likely contribute to nesting duties. Breeding coincides with the monsoon season when grass growth is vigorous.
Migratory Pattern
Resident
Song Description
Song is a rich, varied series of ringing notes and trills, delivered from exposed perches atop grass stems. Calls include sharp ticking and churring sounds, often given when alarmed.
Plumage
Warm brown upperparts with darker streaking, a distinctly rufous rump, and a long, graduated tail. Underparts are buffy to whitish with subtle streaking on the breast and flanks. A pale buff supercilium contrasts with a slightly darker crown.
Diet
Primarily feeds on insects such as beetles, grasshoppers, crickets, caterpillars, and other small invertebrates including spiders. It gleans prey from grass stems and leaf litter and occasionally makes short sallies to capture flushed insects. Seeds may be taken opportunistically but form a minor part of the diet.
Preferred Environment
Forages within dense, tall grasses and reedbeds, often near wet or marshy patches in floodplain systems. Most feeding occurs within a meter of the ground where cover is thick.
