Tawny-flanked Prinia

The tawny-flanked prinia is a small passerine of the family Cisticolidae, 11–12 cm long with a long, narrow, graduated tail and a fairly long, slender bill. The tail is often held erect or waved from side to side. The upperparts are grey-brown with rufous-brown edges to the flight feathers and a rufous tinge to the rump, with a whitish stripe over the eye and dark lores; the tail feathers have a white tip and a dark subterminal band, and non-breeding birds have a longer tail (Wikipedia, general species account).

It feeds on insects and other invertebrates, foraging in small flocks that move through shrubs and undergrowth. The call is short, wheezy and rapidly repeated, and the song a monotonous series of shrill notes. The nest is purse-shaped and woven of grass strips, and two to four eggs are laid. The cached account does not describe India, and the species is not in SoIB 2023, so its place on the Indian list should be checked (Wikipedia, general species account).
