154. Falco cuvieri. Cuvier's Falcon. 

 Fulco cuvieri Smith. 



Iris brown ; bill dark slate-coloured ; legs yellow. 



Cuvier's Falcon was decidedly rare. A female was shot 

 as it flew high over the Hotel garden at Nairobi, but the 

 species was never seen again. 



155. TiNNUNCULUs ALAUDARius. Common Kestrel. 

 Tinnunculus aiaudarius Linn. 



Not at all common in my experience, and only obtained 



at Naivasha. 



156. Tinnunculus cknchris. Lesser Kestrel. 

 Tinnunculus cenchris Naumann. 



Iris dark brown ; bill light blue, yellow at base, tip 

 black ; feet yellow. 



Great numbei's of Lesser Kestrels were attracted by a 

 large prairie fire which broke out near our camp on the 

 Kauti Plains, and it was extraordinary to watch them flying 

 repeatedly through the dense clouds of smoke right into the 

 flames in order to catch the insects. They were common 

 elsewhere. 



157. Haliaetus vocifer. Vociferous Sea-Eagle. 

 Haliaetus vocifer (Daud.). 



Iris yellow-brown ; bill black, yellow at base ; legs 

 whitish-yellow. 



The Vociferous Sea-Eagle was common at Naivasha, and 

 was also constantly seen perched on the tops of tall trees 

 by rivers. A nest which I believe to have belonged to this 

 species was passed one day near the Thika. I had no 

 opportunity of getting up to it, but from below it appeared 

 a very large structure. 



158. Helotarsus ecaudatus. Bateleur Eagle. 

 Helotarsus ecaudatus Gray. 



Bill black ; iris brown ; feet coral-red. 

 Not uncommon near Kallima Theki.
