The rufous-vented grass babbler was described by the English zoologist Edward Blyth in 1844 under the binomial name Eurycercus burnesii.

The upper surface of the wings has barring formed by the covert feathers and their paler fringes.

They molt into adult head and body plumage, retaining their flight feathers, about 4 to 6 weeks after fledging.

The song is described as a warble about 4 seconds long, liquid and loud, comparable to that of a dunnock.

[6] As treated here, this bird is found only in the plains of the Indus in Pakistan and adjacent in Punjab (India).

It can even occur in deserts with scattered patches of tall grass, and reedbeds.

[1][6] This species skulks low in grass tussocks, hopping and threading its way through, often in small groups, feeding on insects.
