Lufira Masked Weaver Ploceus ruweti


Justification of Red List Category
The species is poorly known, though clearly still present at one site, and to date there is insufficient information to estimate range size, population size and trend. As such the species is classified as Data Deficient.

Population justification
This is a poorly known species and no population estimates are available.

Distribution and population

Ploceus ruweti is restricted to Lufira River in the southern Democratic Republic of Congo, and Lake Lafira (now Lake Tshangalele) 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, R. de Cauwer in litt. 2014).


It is found in the swamps bordering Lake Lufira, and at Kiubo Falls (and presumably along the river between these two sites [Craig et al. 2011]), 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.


There is no information on threats to its habitat.
