Description
This small finch is easily identified by the rounded black tail and the bill that is red in all seasons. The rump is red and the breeding male is red on most of the upper parts except for a black eye-stripe, lower belly and wings. There are white spots on the red body and wing feathers. The non-breeding male is duller but has the red-rump while the female is duller with less of the white spotting on the feathers.Evolution and systematics
The Red Munia were earlier included in the genus Estrilda by Jean Delacour. This placement was followed for a while but morphological, behavioural, biochemical and DNA studies now support their separation in the genus Amandava. The Estrildinae are thought to have evolved somewhere in the Indian plate and moving into the African and Pacific regions and it has been estimated that the Red Munia diverged from the Green Munia about 9 mya.Habitat and distribution
Red Munias are found mainly on the flat plains, mainly in places with tall grasses or crops often near water. The species has four named populations. The nominate subspecies is found in BangladeshBangladesh

Behaviour and ecology
This finch is usually seen in small flocks, flying with rapid wingbeats and descending into grass clumps where they are hard to observe. Pairs stay together during the breeding season. These birds produce a distinctive low single note pseep call that is often given in flight. The song is a series of low notes. Birds of a flock will preen each other, ruffling their head feathers in invitation. They feed mainly on grass seeds but will also take insects such as termites when they are available.They build a globular nest made of grass blades. The usual clutch is about 5 or 6 white eggs.
The beak begins to turn red in May and darkens during November and December. The beak then turns rapidly to black in April and the cycle continues. These seasonal cycles are linked to seasonal changes in daylength.
