Juvenal: None seen, but said to be indistinguishable from that of 

 nominate race.

Vidua chalybeata (Muller) 

 Plate 6 



Distribution 



The black-winged combassou differs from the other species of 

 combassous in the blackish (not brownish) remiges of the breeding 

 plumage of the adult male. It ranges from Northern Rhodesia, 

 Nyasaland, Tanganyika, Kenya, Uganda, and the Belgian Congo, 

 north to Ethiopia, Sudan, and French West Africa, west to Nigeria, 

 Gambia, and Senegal. It has become differentiated into five races 

 with the following ranges : 



Vidua chalybeata chalybeata: Savannas and bush country of Upper Guinea from 

 the French Sudan, possibly the French Niger Territory, west to Sierra Leone, 

 Gambia, and to Senegal (Dakar, Kirtaona, Dagama, Richard Toll). 



Vidua chalybeata neumanni: Northern Cameroons (Mayo Sola, Rei Bouba), 

 northern Nigeria (Zaria, Lokoja, Bauchi, Kano), and northern Ghana (Morago 

 River), and the Lake Chad area south to Fort Lamy, and east to Darfur Province, 

 Sudan. 



Vidua chalybeata ultramarina: Southeastern Sudan (Lado, Mongalla, Bahr-el- 

 Ghazal) to Ethiopia (Addis Ababa, Harar, Hawash area, Arussi-Gallaland), 

 north to Bogosland, Tacazzi and to southwestern Eritrea (Archico on the coastal 

 plain of Cunana; not recorded from Dancalia, but said to be fairly generally 

 distributed otherwise in this former Italian colony, chiefly in the hot lowlands in 

 the Acacia savannas), and to Somaliland (Abrona). 



Vidua chalybeata orientalis: Northern half or so of Tanganyika (Pare Mountains, 

 Moschi), Kenya (Taveta, Voi, Machakos, Fort Hall, Kisumu, and many other 

 localities), and Uganda (Entebbe, Jinja, Mabira, Npumu, Buvuma, and Rusinga 

 Islands in Lake Victoria), and the eastern Belgian Congo (Barata, Gabiro, Kisenyi, 

 Rutshuru, Urundi, Usumbura, and Uvera). 



Vidua chalybeata codringtoni: Northern Rhodesia (Molilo's, near Petaukve, and 

 Lupande River, LoangAva Valley), Nyasaland, and Tanganyika (north to Iringa). 



Breeding Season 



What little is known of the time of breeding of the black- winged 

 combassou is based on the following e\4dence: 



Senegal: Richard Toll (a town), October 27, eggs (G. Morel and M. Y. Morel, 

 1955, pp. 281-282); February 22, egg (G. Morel, 1959, pp. 158-159). 

 Gambia: No date, nestling, Ilopkinson (cited bj' Chapin, 1954, p. 569).
