javan munia Lonchura leucogastroides

Plain brown munia with a dark face and a white belly. Similar in appearance to White-rumped Munia, with which it overlaps in southern Sumatra; look out for dark, instead of white rump. Inhabits lowland fields, meadows, wetlands, and edge. Occasionally mixes with other species of munias, particularly when food is plentiful; otherwise found in small flocks, in pairs, and singly. Native to Indonesia; introduced to parts of Malaysia and Singapore.
