First is the extremely common Chestnut Munia Lonchura atricapilla. This bird is all over the place, nesting in housing estates' gardens, traffic islands and even in your potted plant.
Than, the attractive feral Java Sparrow Lonchura oryzivora. Originally introduced as pet birds, the escapees are evidently well established as large party numbering more than 50 birds can be seen congregating to feed on suitable locations here.
Later the rarer White-bellied Munia Lonchura leucogastra palawana, this bird is, unlike its Chestnut Munia cousin, very shy and difficult to approach, it will flee at the slightest sign of you approaching.
Interestingly, Borneo has four races of this. Both Phillipps' and Susan Myer's Fieldguides illustrate the L. l. smythiesi found in western Borneo (Sarawak). The race in Sabah is L. l. palawana, similar to L. l. smythiesi but with less chestnut on the flanks. Also note that only the belly is white, not the vent.
And this is a shot of three of them together, Java Sparrow on top, White-bellied Munia at the bottom.
