Weaver birds in Namibia

David Attenborough examines a remarkable nest of social weavers in Namibia.


Nesting of sociable weavers

The nesting colonies of the Sociable Weaver are amongst the largest bird-created structures.

Sociable weavers construct permanent nests on trees and other tall objects. These nests are the largest built by any bird, and are large enough to house over a hundred pairs of birds, containing several generations at a time. The nests are highly structured and provide birds with a more advantageous temperature relative to the outside. The central chambers retain heat and are used for nighttime roosting. The outer rooms are used for daytime shade. Sociable weaver nests are used commensally by several other bird species, most commonly the Pygmy Falcon.
