The Vulturine Guinea-Fowl was met with only in thick 

 bush in the low country. They were generally shy and in 

 large flocks. They roosted at night in the thorn-trees well 

 back from the river. Their range ceases as the bush gets 

 more open, and shortly afterwards Reichenow's Helmeted 

 Guinea-Fowl appears.

 bill greenish ; legs black. 



Reichenow's Helmeted Guinea-Fowl was met with in the 

 more open country towards the head-waters of the Tsavo. 

 I must have seen several thousand come down to drink 

 at one swamp. They walked out of the bush in flocks o£ 

 twenty or thirty and congregated on the shore. They were 

 very tame. 



Pternistes leucoscepus infuscatus.

This Spur-Fowl was seen in very large numbers on the 

 edge of the Serengeti Plains. It did not occur in the thick 

 bush. It was also fairly numerous in the Kikuyu shambas 

 on the Fort Hall road.
