The white-browed sparrow-weaver (Plocepasser mahali) 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 other non-reproductive individuals.

During his expedition to the interior of southern Africa in 1834–35, Andrew Smith collected specimens of the white-browed sparrow weaver at the Modder River, which he described in 1836, giving it the scientific name Plocepasser mahali.
The White-browed Sparrow-Weaver (Plocepasser mahali) is a bird of modest size, comparable to a sparrow, with a length ranging from 17 to 19 cm. It is predominantly brown with a distinctive broad, white eyebrow stripe and a white rump that becomes conspicuous during flight. Males are marked by a stark black bill, while females exhibit a horn-colored bill, and juveniles possess a pinkish-brown bill. In Zimbabwe, this species may show faint brown spotting across its white breast.
To identify the White-browed Sparrow-Weaver, look for the white eyebrow stripe and the white rump in flight. The male's black bill is a key distinguishing feature, contrasting with the female's lighter bill. The bird's size and general brown plumage also aid in identification.
This species is typically found in dry regions with woodland or wooded grassland. It nests in colonies along thornveld and scrubby, dry riverbanks.
The White-browed Sparrow-Weaver is prevalent in north-central southern Africa, with its range extending from Botswana to Tanzania and western Mozambique, and as far north as Ethiopia. It is particularly abundant in South Luangwa National Park, Zambia, and southern Malawi.
Groups of two to eleven individuals, including one breeding pair and non-reproductive members, are active year-round, engaging in nest-building. The species is sedentary, with populations remaining in the same area.
The bird's vocalizations include a brief "chik-chick" or a loud, fluid whistle of "cheoop-preeoo-chop."
Breeding occurs mainly in the warmer months, although it can be observed year-round. Nests are constructed on the leeward side of trees to withstand weather conditions, with some nests being used by other bird species.
