Amadina leucogastra Blyth, J, A. S. B., xv, p. 286 (1846) (Malay Peninsula). Uroloncha leucogastra. Blanf. & Oates, ii, p. 186.
Vernacular names. None recorded.
Description. Whole head and upper plumage dark chocolate-brown, each feather pale-shafted; upper tail-coverts black; tail dark brown, edged, broadly at the base, more narrowly on the terminal half, with shining golden fulvous; chin, throat, breast and flanks deep chocolate-black; thighs and under tail-coverts the same; abdomen running up into the centre of the breast white, often more or less tinged with fulvous.
Colours of soft parts. Iris dark brown; upper mandible deep plumbeous to black; lower mandible paler and more plumbeous-blue ; legs and feet dusky-plumbeous or dull smalt-blue.
Measurements. Total length about 115 mm.; wing 47 to 49 mm.; tail 31 to 32 mm.; tarsus 13 mm.; culmen 9 to 10 mm.
Young birds are unstreaked brown above with brown upper tail-coverts ; below they are buff, more or less streaked with pale shaft-stripes.
Distribution. Tenasserim from Tavoy South to Singapore and Borneo. Uroloncha leucogastroides (Java) and U. everetti should be treated as subspecies of this form.
Nidification. This is apparently a forest breeder, nests found by Davison and W. A. T. Kellow all being in forest, though in the latter case they were near villages. This Munia makes the usual type of nest but sometimes employs bamboo leaves in its construction. Forty eggs average 15.5 X 11.5 mm.: maxima 16.8 X 12.1 mm. and 16.1 x 12.2 mm.; minima 14.6 x 10.9 and 15.0 x 10.6 mm.
Habits. Those of the genus but it is more of a forest bird than many.
