Lonchura leucogastroides, Javan Munia, Bondol Jawa

Like other MunLonchura leucogastroides, Javan Munia, Bondol Jawaias, Javan Munias eat grass seeds. Their ability to eat the seeds of short grasses may be one of the reasons for their success, they forage in park lawns and open scrub. But they also take seeds from taller grasses.

Javan Munias usually live in pairs or small groups. But they may gather in larger flocks at food-rich sites such as ripening rice fields. They also join flocks of other Munias like the Scaly-breasted Munias.

Breeding: Where food is available year round, Javan Munias breed constantly. Otherwise, they breed mainly in the wet season. A male tries to attract a female with a complex song and when she is within sight, he fans out his tail and leans forwards. He then edges towards her with his belly and flank feathers fluffed out while swaying side to side.

Javan Munias usually nest in trees and bushes. They build globular nests out of dried grass leaves and stems, lined with soft fluffy grass seeds. In Sungei Buloh Nature Park, these little birds are particularly fond of nesting in the potted ferns that hang along the visitor centre. This habit of nesting in ornamental plants was also observed in hotels in Bali . 5-6, up to 9, white eggs are laid. Both parents may incubate, or just the female with the male standing guard and chasing off other Javan Munias. The eggs hatch in 13 days and the young are fed regurgitated seeds, the parents choosing soft ripening seeds rather than hard, dry ones. After they fledge in 18-20 days, the young may stay with the parents near the nest for some time.

Status and threats: Javan Munias are often considered a pest on paddy and other grain crops. They are often caught with other Munias, but never in very large numbers.
