Sociable Weaver

The sociable weaver, a small bird measuring approximately 14 cm in length, is adorned with a distinctive black chin. Its flanks are barred black, and its back is elegantly scalloped. Weighing between 26 and 32 grams, the sexes are visually indistinguishable from one another.

Identification Tips

When observing these birds, look for the black chin as a key identifier. The barred pattern on the flanks and the scalloped back are also characteristic features that can aid in identification.

Habitat

The sociable weaver is strongly associated with the arid savannas of the southern Kalahari region, where it thrives amidst the stiff grasses that are crucial for its nesting material.

Distribution

This species is predominantly found across northwestern South Africa, southwest Botswana, and extends across Namibia. Its range is notably centered within the Northern Cape Province of South Africa.

Breeding

Breeding may take place throughout the year, depending on the region and rainfall. Breeding for the sociable weaver can occur at any time of the year in the southern parts of its range but in the northern range, a distinct breeding season between December and August is observed. Sociable weavers may forgo breeding during dry years, and many individuals may not breed in a given season. They are capable of raising multiple broods per cycle and exhibit delayed-onset breeding, sometimes waiting until two years of age. The species is known for its cooperative breeding behavior, with nearly all pairs receiving assistance from helpers.

Diet and Feeding

The sociable weaver's diet is primarily insectivorous, with insects making up 80% of its diet. It also consumes seeds and other plant products, foraging mostly on the ground but also on tree bark and leaves. Remarkably, it obtains all necessary water from its food, an adaptation to the dry Kalahari Desert.

Conservation status

The sociable weaver is currently listed as Least Concern. Populations have increased, possibly due to the availability of man-made structures for nesting. However, habitat alteration and overgrazing may pose threats in certain areas.
