Scaly-breasted Munia

Overview

The scaly-breasted munia (Lonchura punctulata), also known as the spotted munia, is a sparrow-sized estrildid finch native to tropical Asia. Its name derives from the distinct scale-like feather markings on its breast and belly, and it is listed as least concern on the IUCN Red List.

Identification

• Small bird measuring 11–12 cm in length with a stubby, dark conical bill typical of grain-eating species.
• Adults have brown upperparts and a dark brown head, while the underparts are white with dark scale markings.
• Males display darker markings on the underside and a darker throat compared to females.
• Immature birds possess pale brown upperparts, lack the dark head of adults, and have uniform buff underparts.

Habitat

This species is endemic to Asia, ranging from India and Sri Lanka east to Indonesia and the Philippines, and inhabits tropical plains and grasslands usually close to water. Although it can be found in the foothills of the Himalayas at altitudes near 2,500 m, it is primarily a plains species and has been introduced to various parts of the world, including Puerto Rico, Hispaniola, and parts of Australia and the United States.

Diet

The scaly-breasted munia feeds mainly on grass seeds, small berries such as those of Lantana, and insects. It forages in flocks, often employing a scrounger tactic to join others that have found food, and may also consume algae prior to the breeding season for its protein content.

Did you know?

In Southern California, the species serves as a brood host for the parasitic pin-tailed whydah, raising its chicks as its own in a novel relationship since the two species do not naturally co-occur in their native ranges.
