The chestnut munia or black-headed munia (Lonchura atricapilla) is a small passerine. It was formerly considered conspecific with the closely related tricoloured munia, but is now widely recognized as a separate species. This estrildid finch is a resident breeding bird in Bangladesh, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Burma, Nepal, the Philippines, Singapore, Taiwan, Thailand, Vietnam and Hawaii. It also has been introduced to all the Greater Antilles and Martinique in the Caribbean.
Before 1995, it was the national bird of the Philippines, where it is known as mayang pula because of its brick red patch on the lower back which is visible only when it flies.
