Also known as the spotted-backed weaver or black-headed weaver is a species of bird found in much of sub-Saharan Africa.
It has also been introduced to Hispaniola, Mauritius and Réunion.
This often abundant species occurs in a wide range of open or semi-open habitats, including woodlands and human habitation, and frequently forms large noisy colonies in towns, villages and hotel grounds.
This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward facing entrance which is suspended from a branch in a tree.
This is a colonial breeder, so many nests may hang from one tree.
