Adult non-breeding male: Duller than the breeding male, with a brown bill, and often without the dark face.

Immature: Similar to the female, but greener above.

Distribution

South Africa, Lesotho and Swaziland.

Taxonomy

This is a monotypic species[1]. Some authors recognise three subspecies[2], but these are poorly defined: There is considerable variation within flocks and regional variation is largely clinal.

Habitat

This common species occurs in grassland, agricultural and fynbos habitats, often near rivers. Frequently roosts and breeds in reedbeds.

Behaviour

Usually in flocks, often feeding with other seed-eating species.

Diet

Forages on the ground (often turning over small stones and dried animal-pats), in trees and shrubs (sometimes stripping bark) and aerially for seeds, invertebrates, fruit and nectar.

Breeding

Polygynous, each male breeding with as many as seven females, usually in noisy colonies with up to 20 other males. These colonies are found in trees (often willows or Eucalyptus, rarely palms) and reedbeds. The males build large coarsely woven nests made of grass and leaf strips with a downward facing entrance. They are built between two reed-stalks or suspended from the tip of a branch. Two to five eggs are laid from June to January.

Parasitised by the Dideric Cuckoo.

The Hadada Ibis will sometimes nest in the weaver colonies.
