Many weavers choose acacia trees to breed in - acacias have thorny twigs that may help support the nest (sparrow weavers and buffalo weavers) or may provide some protection against predators. Many of the weavers that nest in acacias are typical savanna species. The list below shows weavers that often like to build their nests in acacias. Several weavers do not normally breed in acacias but there are single, or a few, records of this nest site, eg. Black-winged Bishop Euplectes hordeaceus, Golden-backed Weaver Ploceus jacksoni, Southern Brown-throated Weaver Ploceus xanthopterus, and Dark-backed Weaver Ploceus bicolor. The Holub's Golden Weaver Ploceus xanthops may breed in acacias along rivers.
