Social Weaver

About the Social Weaver

The sociable weaver (Philetairus socius) is a species of bird in the weaver family, endemic to Southern Africa. It is the only species in its genus Philetairus. It is found in South Africa, Namibia, and Botswana, but its range is centered within the Northern Cape Province of South Africa. The species builds large, compound, community nests, a rarity among birds. These nests are perhaps the most spectacular structure built by any bird.

The sociable weaver was first described by ornithologist John Latham in 1790. Alternative names include the common social weaver, common social-weaver, and social weaver. Formerly, four subspecies were recognised, but the species is now considered monotypic. The sociable weaver is the only extant species in the genus Philetairus.

Based on a 2017 DNA-analysis, P. socius belongs to the group of sparrow weavers (subfamily Plocepasserinae) and is most related to the genus Pseudonigrita. These two genera are the sister group of the genus Plocepasser. The most basic genus of the subfamily is Sporopipes. Provided that genera are correct clades, the following tree expresses current insights.
