thence northward as far as the Okavango ; but I nowhere 

 found it common. The few that I saw were either single 

 or in pairs, perching on the larger trees and hunting on 

 the branches with great assiduity for larvae and insects, 

 especially beetles and ants. 



The notes of this species are harsh and loud. It is

 southward it becomes more numerous, till on reaching 

 Cape Town it is found in every garden. In Damara 

 Land I have usually found it very shy and retired in its 

 habits, quickly escaping, the moment it finds itself ob- 

 served, into the thickest part of the nearest bush, and
