about 4 feet in diameter, of sticks, and laving a single egg of 

 a dirty white colour, sometimes blotched with reddish- brown. 



The African White-backed Vulture (Pseuclogyps africanus) 

 is a little-known bird, differing mainly from the other species 

 in the possession of a pure white lower back and rump. 



It is brown above and pale brown below. It is essentially 

 a Tropical African species, but was found breeding in some 

 number in June, near Potchefstroom, Transvaal, by Major 

 Sparrow, of the 7th Dragoon Guards. Some doubt was 

 expressed by Mr. W. J.. Sclater, in his Check-list, as to the 

 identification of the species, one specimen, forwarded to the 

 South African Museum by A. Roberts, possessing fourteen 

 tail feathers, whereas the genus Pseudogyps is characterised 

 by the possession of twelve only. There is, however, a 

 specimen from Potchefstroom now in the Transvaal Museum 

 (received June 6, 1907), which is an undoubted example of 

 the White-backed Vulture, with tivelve tail feathers. In 

 Northern Rhodesia this bird appears to be the common 

 species, as the examples procured at Monze, in November, 

 1919, as well as those received at the National Zoo, from 

 Pemba, were of this variety. 



The last of the Vulture tribe which concerns us is the 

 Egyptian Vulture (Neophron percnopterus), a much smaller 

 bird than kolbii or auricularis, and immediately distinguish- 

 able by the bristle-like ruff on the back of the head, and by 

 its slender beak. It is somewhat evenly distributed over 

 South Africa, being, however, according to Major Kirby, 

 more common in the Eastern Transvaal. There are specimens 

 in the Pretoria Zoological Gardens from the Ermelo district. 



RAVENS 



The White-necked Raven breeds on a shelving rock or 

 in a hole, on the face of a krantz in some w T ooded kloof.
