Yellow-rumped Munia Lonchura flaviprymna

Small finchlike bird with brown wings, pale bill, and yellowish rump. Found in areas with tall grass, often in flocks beside rivers or floodplains, sometimes mixed with other seed-eating species. Pale gray head contrasts with dark brown back and wings, underparts pale buff, and rump and tail dark yellowish tone. Juvenile very plain, easily confused with juvenile Chestnut-breasted (which has less uniform upperparts) or Pictorella Munia (which has shadow pattern of dark ear coverts, recalling adult’s).
