Discovery
IntroductionThe Chestnut-mantled Sparrow-Weaver was formally described by Dr Johann Buttikofer, a Swiss zoologist. Buttikofer undertook two zoological expeditions to the Republic of Liberia, so he had some experience of African birds.The Chestnut-mantled Sparrow-Weaver was collected by Pieter Jacob van der Kellen, a Dutch naturalist, collector and explorer in southern Angola, who was working for the Dutch Natural History Museum in Leiden. Van der Kellen took part in the Dutch Ethnographic Museum’s South West Africa (=Angolan) expedition (1884-1885), and stayed on in Angola until 1888. His job was to act as a hunter and to search for and collect ‘interesting’ animals. Van der Kellen visited the Kasinga River four times, the first two trips being in December 1886 and January 1887. It was only on the third visit (27 February – 11 March 1887) that he collected the Chestnut-mantled Sparrow-Weaver. The first illustration of the Chestnut-mantled Sparrow-Weaver was of the male type specimen, published by Buttikofer (1888). The next illustration to be published was some 6 decades later in Chapin (1954).

1. Basic biology
 Identification. The Chestnut-mantled Sparrow-Weaver, or Chestnut-backed Sparrow-Weaver, is a large sparrow-like weaver with heavy black and white head stripes and chestnut back and 2 white wing-bars. The bill is usually white in the male, and black in the female, but this is variable. Its miombo habitat further helps separate it from the White-browed Sparrow-weaver where their ranges meet in Angola and Zambia. Distribution. The Chestnut-mantled Sparrow-Weaver is found from south-west Angola, through SE DRCongo and Zambia to western Tanzania (near Mpanda) and north-western Malawi (see map above based on Birds of Africa).  Habitat. The Chestnut-mantled Sparrow-Weaver is restricted to miombo (Brachystegia) woodland. It sometimes joins mixed species flocks moving through the mid-stratum, and often perches inconspicuously in trees. Food. The diet of the Chestnut-mantled Sparrow-Weaver is seeds, including grass seeds, and it presumably also eats insects. Groups of up to 15 birds forage on the ground. Breeding. The mating system of the Chestnut-mantled Sparrow-Weaver is unknown but it may be a co-operative breeder like the White-browed Sparrow-Weaver. The Chestnut-mantled Sparrow-Weaver is colonial, with small groups of nests in Zambia, but in Angola, it is usually a solitary nester. The nest is an untidy domed mass of grass with 2 entrances, one of which is closed off when the eggs are laid, thus resembling the nest of the White-browed Sparrow-Weaver. The nest is placed in a cluster of small branches at the end of a branch in trees. The eggs are whitish, and heavily spotted with reddish brown at the thick end. Nothing else is known about its breeding habits. Bohm’s Flycatcher Muscicapa boehmi has been recorded breeding in old nests of this weaver. |
