Chestnut Weaver Movements in Southern Africa
The Chestnut Weaver Ploceus rubiginosus is found disjointly in south-western and in eastern Africa. The southern race occurs in Namibia, Botswana and Angola. It is a nomadic species and appears to move in response to rainfall in its arid environment(Braine & Braine 1971, Winterbottom 1971). Similarly, in eastern Africa its extensive movements are stimulated by rainfall, and occurrence is seasonal in most areas (Lewis & Pomeroy 1989). There is one published account of a long distance movement. A full grown bird ringed on 6 December 1974 at Ngulia, Kenya, was recovered on 3 May 1975 at Migwani, Kenya, a distance of 213 km(Backhurst 1977); the bird was caught and not released. Here the movements of Chestnut Weavers in southern Africa, based on ringing and published records, are briefly reviewed.
