UP-Diliman, Quezon City, Philippines, 8 April 2006

10–12½ cm (4-5 in)
Adult: both sexes identical with cinnamon-brown back and head, at least sometimes with darker face and throat. The breast and the rest of the underside is mostly white with each feather showing narrow borders and stripes in brown producing a scaly pattern. Pattern varies with the subspecies. Sometimes scales are single, sometimes doubled on each feather. Also varies in extent of scaling in the throat area.
Juvenile is slightly lighter than the adult on the back, while the underside is buffy, gradually lighter towards undertail coverts and lacking in the scaly effect. Bill is black in both adult and juveniles.

Similar Species

Juveniles are similar to juvenile Chestnut Munia, but distinguished by Scaly-breasted's black rather than bluish bill.

Distribution

The natural distribution is from Nepal through India and Sri Lanka and east from there through China and the far east to Philippines and Indonesia.

In addition, this species is common in the pet trade, and has generally established populations that spreads from wherever escapes have happened. They are therefore present along the east coast of Australia, the Caribbean and the USA, just to mention a few of the locations where they have been introduced.

Taxonomy

Twelve subspecies share the original range. Birds in the pet trade are unlikely to come from any single subspecies, so introduced populations likely represent a mixture; even so, birds in Australia and the Caribbean do not look identical.

Nest is a loosely constructed ball with a low side entrance. Outside made of flowering grass heads, leaves and twigs. Internal chamber lined with fine grass. Occasionally will use old nest of another bird. Clutch is 3-6 eggs with larger clutches suspected of being the result of two or more females laying in the same nest. Nesting can occur at any time of the year if conditions are favourable, and the nest is normally found at moderate height in a bush or tree.
