The black-headed weaver (Ploceus melanocephalus ), also known as yellow-backed weaver, is a species of bird in the family Ploceidae.
Medium-sized weaver. Breeding males are striking with their black face and neck and dark brown irises contrasting with their yellow body. Females and non-breeding males are similar, with a yellow breast and white belly. Usually found in marshy areas with tall grass. Nest is built in a basket shape, weaving together grass and sticks hanging from trees.
Breeding males have a black head and yellow nuchal collar, which is absent in the Juba and golden-backed weavers. It also differs from the latter species and village weaver by its plain, greenish mantle plumage. The pale yellow underpart plumage is suffused with a variable amount of chestnut.
The female and non-breeding male lack the black head, and resemble a female masked weaver, except that they have dark eyes and a darker bill. Their buffy breast plumage also distinguishes them from non-breeding golden-backed weavers.

It occurs in West, Central, and East Africa, but it has also been introduced to the Iberian Peninsula. It is found in savanna and similar habitats, typically near water. It often lives on an Acacia tree 3 meter away from land to prevent predation.
