Facts about this animal
The sociable weaver is a sparrow-sized passerine with a total length of 14 cm and a body-weight of 26-30 g. Sexes look alike, buff-brown above, scaled pattern on back, nape and wing-coverts, buff-white below with scaled flank-patches, and a blackish throat patch extending to lores.
Sociable weavers live in large flocks, usually spending much time on the ground where they feed on seeds and insects.
Sociable weavers build communal nests, which, from a distance, resemble haystacks hanging in a tree. A nest may be occupied by up to 100 sociable weaver families all year long. It has many nest entrance tunnels which can be up to 25 cm long and 7 cm wide. Round, cozy nesting chambers are usually 10-16 cm in diameter.Some sociable weaver nests have remained occupied for over 100 years.
The female produces a clutch of 2-6 eggs, which are incubated by both parents for about 13 days. The young fledge after 21-24 days.
Did you know?
that the nests of sociable weavers are temperature-controlled? Large nests help the sociable weavers stay comfortable in the harsh climate of the Kalahari Desert. During freezing winter nights a move to the nest’s well-insulated centre chambers helps the little birds stay warm. Scorching summer temperatures are easier to weather when roosting in one of the outer chambers of the nest.

Why do zoos keep this animal
Sociable weavers are not a threatened species. Their interesting social behaviour is however of major educational interest, and they are a good ambassador species for the conservation of southern African aridlands, in particular if dispayed as part of a multispecies themed exhibit.
