The White-rumped Munia, known scientifically as Lonchura striata, is a diminutive passerine bird belonging to the waxbill "finches" family, Estrildidae. This species is not closely related to the true finches or sparrows. It is characterized by its small size, approximately 10 to 11 cm in length, with a stout grey bill and a sharply pointed black tail. The plumage is generally brown above and on the breast, with a paler underside and a distinctive white rump.
Adult White-rumped Munias exhibit brown upperparts and breast, with lighter underparts. The white rump is a key distinguishing feature. While there is some variation among subspecies, males and females are nearly indistinguishable, though males may possess a slightly more robust head and bill.
This species thrives in open woodlands, grasslands, and scrub areas. It is also quite adept at adapting to agricultural landscapes. The White-rumped Munia is often found near water and is known to feed on algae, particularly in paddy fields.
The White-rumped Munia is a common resident breeder across the Indian subcontinent, extending to southern China, Taiwan, and Southeast Asia down to Sumatra.
