Birds from British East Africa. 519 



159. BuTEo AUGUR. Augur Buzzard. 

 Buteo augur Riipp. 



Iris brown ; cere yellow ; bill blacky yellow at base ; legs 

 whitish-yellow. 



A common species, but, like all the larger Hawks, of 

 extreme wariness. A pair were breeding in a cleft in one 

 of the precipices on the far side of Longonot. 



160. MiLvus iEGYPTius. Ycllow-billed Kite. 

 Milvus (Bfjijptms (Gmel.). 



Iris hazel ; bill and legs yellow. 



Contrary to the habits of all the other Hawks, this Kite, 

 which was very common, was extraordinarily tame. At 

 several of our camps on the Athi it was always soaring 

 round or sitting on the trees near, and would even fly down 

 to where Mr. Groves was skinning birds and pick up bits of 

 meat at his feet. 



161. Milvus migrans. Black Kite. 

 Milvus migrans Strickl. 



Iris pale greyish-yellow ; bill black, yellowish at base ; 

 feet yellow. 



Certainly not obtained often, and, I think, not seen very 

 frequently. It appeared to me to be rather rare. 



162. Elan us c^ruleus. Black-shouldered Kite. 

 Elanus cceruleus (Desf.). 



Iris crimson ; bill black, yellow at base ; legs yellow. 



Obtained at Naivasha and Kallima Theki. At the latter 

 place it was fairly common, and two or three might often 

 be seen sitting on the top of a tree, from which they would 

 keep a sharp look-out all round. It was not particularly 

 shy, and it was generally easy to get within gunshot. An 

 individual which I tipped in the wing and kept alive for some 

 weeks preferred insects and grasshoppers for food to birds 

 or mice. 



163. Circus iERUGiNosus. Marsh-Harrier. 

 Circus (Bruginosus Savign. 



Iris yellow ; feet yellow ; claws black. 

 The Marsh-Harrier was very common at Lake Naivasha.
