Gambaga and Kwobia. 



This bird frequents bush-country, and may be seen singly 

 or in small parties travelling from one thick-leaved tree to 

 another, uttering the whole time a chorus of loud chirps. 

 Lizards form its principal food. The flight is even and very 

 straight. Its pose, when perched, is like that of a Shrike. 

 In immature individuals the upper parts are washed with 

 rufous, especially noticeable on the scapulars and rump ; the 

 inner secondaries are much barred with brown and edged 

 with pale rufous ; there is a broad eye-stripe of dirty white ; 

 the feathers of the breast have brown subterminal margins ; 

 and there is a large patch of pale rufous on each side of the 

 breast. 



In the adult the general colour of the upper surface is ashy
