Geographic Range [top]

Range Description: Ploceus ruweti is restricted to Lake Lufira in the southern Democratic Republic of Congo, where it was common in 1960 (when the type-specimen was collected) and readily observed on recent "rediscovery" visits (Louette and Hasson 2009, Craig et al. 2011).

Habitat and Ecology [top]

Habitat and Ecology: It is found in the swamps bordering Lake Lufira, where it occurs in reedbeds of Phragmites and Typha (usually in Aeschynome elaphroxylon trees standing in water, rather than on the reeds themselves), interspersed with bushes and Sesbania leptocarpa, as well as on dry land in the trees bordering cultivated maize fields. It is generally restricted to within 100 m of the water's edge. The breeding season lasts from January until April, and colonies vary in size from 3-20 nests; nests are often found in Acacia trees (Craig et al. 2011). Birds normally raise two broods per breeding season.

Systems: Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat: Unknown
