Black-capped Social Weaver Pseudonigrita cabanisi
IntroductionThe Black-capped Social Weaver was formally described jointly by Gustav A Fischer and Anton Reichenow, the latter being a German ornithologist and herpetologist.
The Black-capped Social Weaver was collected by Gustav A Fischer, a German African explorer. He collected a large number of birds, including new species, in East Africa.
Fischer settled as a physician in Zanzibar in 1876, from where he undertook expeditions to Tanzania and Kenya. His third trip started in late 1882 at Pangani on the Tanzanian coast and he followed the Pangani River upstream. When he reached the Pare Mountains in March 1883, he collected the type specimen of the Black-capped Social Weaver. He continued to Kilimanjaro and appears to have collected another specimen in the same area on his return. Fischer saw the Black-capped Social Weaver in small groups in acacia bushes and he also found small colonies of nests.
The first illustration of the Black-capped Social Weaver was of the type, published by Shelley (1888). The second illustration for the species was a line drawing many decades later, in Mackworth (1955).
