especially along the Molopo River. The habits of both are 

 much alikCj but the Pied Babbler is far more inquisitive, and 

 if a person sits down in the bush and remains perfectly 

 motionless a party of these birds is almost certain to be 

 attracted. At first they keep at some distance, hopping 

 nervously round and chattering incessantly ; but as they 

 gain confidence they come nearer and nearer and become 

 less noisy, till eventual^ several will take up positions 

 within a few feet and remain almost silent, turning their 

 heads from side to side as if trying to ascertain whether 

 the curious animal looks equally curious vicvv'ed with each 

 eye separately ! The slightest movement sends them to a 

 distance, chattering more noisily than ever.

Hartlaub's Babbler is a very common bird in Ngamiland. 

 It generally frequents the rather dense belts of bush which 

 separate the mopani forest from the marshes. It seems 

 always to be moving about in parties of from five to a dozen 

 individuals, which are very noisy when disturbed and rather 

 inquisitive, but not to the same extent as C. bicolor.
