Katanga Masked Weaver Ploceus katangaeIUCN: Least concern Discovery: 112
IntroductionThe Katanga Masked Weaver was formally described by Rene K. Verheyen, a Belgian ornithologist.
The Katanga Masked Weaver was collected by Hans J Bredo, a Belgian government entomologist, who also collected many birds in Central Africa in the 1930s. Bredo wrote many papers on insects, especially locusts. Bredo collected two specimens, both adult males, of the Katanga Masked Weaver, near the station at Musosa, where he was based. Musosa, NE of Lake Mwero, was part of the Belgian Congo (in Katanga Province) but now lies just within the borders of Zambia.
The Katanga Masked Weaver was described as a subspecies of the Southern Masked Weaver by Verheyen. This has been followed by many authors initially, but it is considered a separate species by a growing number of authors.
The Katanga Masked Weaver was first illustrated by Benson 1971b as a colour painting of a male. The next illustration of the species was published in Mackworth 1973a, showing both male and female.

1. Basic biology
The Katanga Masked Weaver breeding male is yellow with a black mask. It is distinguished from the Southern Masked Weaver by having more saffron around the mask, less black on forehead, and a darker green back. It has much less saffron around the mask than in the Tanganyika Masked Weaver and the Lufira Masked Weaver. The yellow green rump is conspicuous in flight. Female and young birds are dull coloured. This species is smaller than the Southern Masked Weaver.
The Katanga Masked Weaver is found in DRCongo and Zambia (see map below, based on Birds of Africa). There are 2 subspecies:
Habitat. The Katanga Masked Weaver inhabits swampy areas, especially when breeding. When not breeding, it may move locally to join mixed bird parties in miombo woodland up to 7 km from water, while others remain in the swamps.
Food. The diet of the Katanga Masked Weaver is unrecorded but it probably feeds on seeds and insects.
Breeding. The Katanga Masked Weaver is probably polygynous, and it breeds in small colonies although solitary nests with 1 male per site also occur. The nest is kidney-shaped with the entrance below and no tunnel, being similar to that of Southern Masked Weaver. Nests are placed in reed and papyrus beds in swamps, or in bushes or trees near lakes.
The eggs (1-2) are pale greenish or greenish blue, spotted with bright brown and light chestnut spots.
