Red avadavat (Amandava amandava)

The red avadavat, red munia or strawberry finch, is a sparrow-sized bird of the family Estrildidae. It is found in the open fields and grasslands of tropical Asia and is popular as a cage bird due to the colourful plumage of the males in their breeding season

They inhabit the flat plains and are usually seen in places with tall grasses or crops often near water. Introduced populations also exist in southern Spain, Brunei, Fiji, Egypt, Malaysia, Portugal, Puerto Rico, Singapore and Hawaii. In their natural habitat, they breed in the monsoon season. They build a globular nest made of grass blades. The usual clutch consists of 5 or 6 white eggs.

This small finch is easily identified by the rounded black tail and the bill that is seasonally red. 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.

Red avadavats are found mainly on flat plains, in places with tall grasses or crops, often near water.The species has four named subspecies. The nominate subspecies is called amandava and is found in Bangladesh, India, Sri Lanka, Nepal and Pakistan; the Burmese form is called flavidiventris (also found in parts of China, Indonesia, Thailand and Vietnam);the population further east in Java is called punicea and in Cambodia, decouxi.

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 five or six 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.

Two ectoparasitic species of bird lice (an ischnoceran, Brueelia amandavae, and an amblyceran, Myrsidea amandava) have been identified living on them and a paramyxovirus has been isolated from birds kept in Japan.
