The white-headed munia(Lonchura maja) is a small passerine bird belonging to the estrildid finch family. This species is often confused with, and referred to as, the Pale-headed munia (Lonchura pallida) which can be differentiated by tan coloured flanks which are lighter than the brown wings and also by the absence of the black belly.

Taxonomy

The white-headed munia was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Loxia maja. [2] Linnaeus cited George Edwards's "The Malacca Gros-beak" and Mathurin Jacques Brisson's "Le Maia de la Chine". [3] [4] The English naturalist John Ray used the word "Maia" for a Cuban bird in 1768. [5] [6] Linnaeus specified the locality as East India. This was amended to Malacca in 1924. [7] The white-headed munia is now placed in the genus Lonchura that was introduced by the English naturalist William Henry Sykes in 1832. [8] [9] It is treated as monotypic: no subspecies are recognised. [9]

Appearance and size

The White-headed munia has a distinctive chocolate-brown body and a contrasting white head and throat. They are typically 11 cm in length and weigh around 11 grams. Adult birds have chestnut brown upperparts, flanks and wings, an entirely white head, throat, and upper breast which is tinged with buff. The tail is black-brown and the belly is black. The bill and legs are light grey.

Sexual dimorphism

There is very subtle sexual dimorphism in adult birds [10] , with the head of the male being whiter than that of the female, and getting whiter with age. This often causes young male birds to be confused with females. Additionally the definition line between the breast and the flanks is more pronounced in the male.

Juveniles

Juvenile birds are more cinnamon coloured above with a buff face and underparts, a brown iris, grey bill and blue-grey feet. They are practically impossible to differentiate from juveniles of other species such as the White-capped munia (Lonchura ferruginosa), Pale-headed munia (Lonchura pallida), Chestnut munia (Lonchura atricapilla) or the Scaly-breasted munia (Lonchura punctulata).

Distribution and habitat

This species is native to Southeast Asia, including countries like Indonesia, Thailand, Malaysia, Vietnam and Singapore. [11] White-headed munias are commonly found in tropical and subtropical habitats, including grasslands [12] , wetlands, and cultivated areas. [13] They are often associated with rice fields.

Diet, social behavior, nesting, and breeding

Diet

The White-headed munia’s diet mainly consists of seeds, especially grass seeds and rice grains. [14]

Social behavior

The White-headed munia are social birds and are usually seen in flocks.

Nesting

Breeding

The breeding season of the White-headed munia usually coincides with the availability of food, often during or after the rainy season. This can vary depending on the specific location. [17]
