Черногрудая муния Lonchura teerinki

A small bird of mid-montane grasslands in western New Guinea. Black face and chest, brown upperparts, yellow rump and tail, yellow sides and white belly bordered with a black line, and a thick, silver-blue bill. Usually seen in small flocks. May have a slight altitudinal overlap with Snow Mountain, but Black-breasted Munia is normally lower and has a black chest. Call, a squealing “week!” repeated constantly.
