are also attracted to man's agricultural activities and the adult 

 ticks frequent tall grass in search of hosts. All these factors 

 bring man and tick closer together. 



When dragging for ticks in Nyanza Province of Kenya, Lewis 

 (1931c) obtained adult glossy ticks only in shady woodlands while 

 the other species, R. appendiculatus , A. variegatum , and H. 

 leachii were obtained from open country with grass and toishes. 



In Moreau*s (1933) study of the food of the tickbird, Buphagus 

 orythrorhynchus (Stanley), in Tanganyika, fifteen specimens of R. 

 s. siraus were found in the stomachs of fovir of 58 birds examinee!. 

 Tn Kenya, van Someren (1951 ) examining the stomachs of twelve of 

 the same kind of bird found four females in two of them. He found 

 seven adults in three out of seven stomachs of B. a, africanus.
