Black-headed weaver

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.

[2] The pale yellow underpart plumage is suffused with a variable amount of chestnut.

[2] It occurs in West, Central, and East Africa, but it has also been introduced to the Iberian Peninsula.
