FALCONIDJE. 11 



[The notes of coloration given above by Mr. Andersson have 

 probably been taken from a bird not fully adult, as in old birds 

 the feet and bare skin between the eye and the bill are of a 

 coral-red. It is, however, remarkable (as I am informed by Mr. 

 Bartlett of the Zoological Society's Gardens in the Regent's 

 Park) that, if the bird be irritated, the coral-red of all these 

 parts fades temporarily to an orange-yellow, as he has frequently 

 observed in the case of living specimens which he has had under 

 his care. Mr. Chapman (loc. cit.) states that this species is 

 found at Lake Ngami, and gives a remarkable account of his 

 being fiercely and pertinaciously attacked by one of these birds, 

 at which he had fired as it was sitting on its nest : this nest, like 

 those observed by Mr. Andersson, was on a tree ; but an instance 

 of this Eagle nesting on a rocky cliff is recorded in ' The Ibis/ 

 1868, p. 140. ED.] 



15. Buteo jackal (Daud.). Jackal Buzzard. 



Le Rmmoir, Levaillant's Ois. d'Afr. pi. 16. 

 Buteo jackal, Layard's Cat. No. 8. 



To the best of my belief this Buzzard has never been 

 observed in Damara Land ; and it is scarce in Great 

 Namaqua Land, where, indeed, I have only occasionally 

 observed it in the southern parts, usually in the neigh- 

 bourhood of rocks, on which it perches. 



When hunting, it soars steadily aloft, swooping down 

 suddenly with great force and velocity. 



Its chief food consists of moles, rats, mice, lizards, 

 and insects.
