White-headed Munia

A medium-sized, sociable estrildid finch with a distinctive white head and chestnut flanks, white-headed munias inhabit forests, secondary growth, and rice fields across Southeast Asia from Thailand to the Philippines. They are highly gregarious, foraging in large flocks on grass seeds and rice. Their white head sharply contrasts with the dark brown body, making them one of the more visually distinctive munias. Popular aviary birds in Asia, they breed readily in captivity.
