The Red-headed Weaver has several forms. This bird is one of them. It is better called Red-headed Weaver, but one source allowed that this was now grouped with the Malimbe weavers — and I ran with that. As the taxonomy clears I will add/change/corect the terminology.
Africa is rich in Weaver birds. At least 56 species have Weaver in their name. The Red-headed Malimbe is one of them. There are five Malimbes amongst the weavers and generally they are black with some red. The one mentioned is mostly red with some black. It happens to be a loose colonial nester. There are a few nests in a Fever Tree (Yellow-barked Acacia) right next to the African Tulip Hotel here in Arusha Tanzania.
