Distribntion. — This, a somewhat rare Hawk, is confined to the 

 southern half of Africa. The type was obtained by Dickinson 

 at Chibisa, on the Shire river in Nyasaland, and it has also been 

 found in the Zambesi valley, from whence it ranges to Ovampo- 

 land and Benguella in the west and to the Rovuma valley in the 

 east. 



South African localities are : Rhodesia — Tamafopha, between 

 Bulawayo and the Victoria falls, April (Bradshaw and Holub), Chobe 

 river (Bradshaw in S. A. Mus.), Salisbury (Marshall in litt.) ; Portu- 

 guese east Africa — Tete on the Zambesi, August (Alexander) ; 

 German south-west Africa — Ochimbora in Ovampoland, November 

 (Eriksson in S. A. Mus.). 



Habits. — Little is known of the habits of this Kestrel ; Holub 

 states that it preys chiefly on small birds such as weavers and 

 finches, and that it lives in small companies. Anchieta found that 

 it appeared in flocks in August in Caconda, and fed on insects 

 disturbed by grass fires. Mr. Whyte found it nesting in Nyasaland 

 in the fronds of tall palms, and it is probably a resident throughout 

 its range.
