The Southern Masked Weaver is a common inhabitant of savannas, woodlands, grasslands, riverine thickets in arid areas, and suburban gardens, feeding on insects, nectar and seeds.
The breeding season stretches through spring and summer, when the males don their brilliant black-and-yellow plumage and try to breed with as many females as possible, attracting them with neat nests weaved of grass or palm throngs on thin twigs or reeds (or wires and fences), usually hanging over water. Southern Masked Weavers normally move around singly or in small groups, but breed colonially. Only the female incubates the clutch and rears the chicks.
The IUCN considers the Southern Masked Weaver to be of “least concern” as they are common all over their distribution range, which covers Angola, Zambia, Malawi, Mozambique, Botswana, Namibia and all of South Africa, Lesotho and Swaziland.
