The white-browed sparrow-weaver (Plocepasser mahali, valkokulmakutoja in Finnish) is a predominantly brown, sparrow-sized bird found throughout central and north-central southern Africa. It is found in groups of two to eleven individuals consisting of one breeding pair and nonreproductive individuals and build several nests in one tree.
When a predator nears the territory of white-browed sparrow weavers, all the birds chirp in chorus in an audible example of their cooperative habits. They search for food in flocks of 20 or more birds.
Other birds, such as red-headed finches, sometimes use the nests of white-browed sparrow weavers. The main predators of sparrow weavers are falcons and kites. Vervet monkeys and snakes raid the nests to eat the eggs and chicks.
