Upper White Volta. 



This beautiful Bush-Shrike haunts thick undergrowth on 

 the banks of the Volta River, being distributed in pairs from 

 source to mouth. We never found it in any other locality, 

 and it is essentially a river-loving species. In April it was 

 breeding. From two of the specimens obtained we took 

 out complete eggs. At that time the male birds were very 

 noisy, uttering at short intervals throughout the heat of the 

 day their loud peculiar notes, like the clang of a broken bell, 

 which were often followed by a whirring noise made by the 

 wings.

Breeds in April. The call of this species is loud and 

 flute-like. We observed it frequenting acacia-trees and 

 picking off the young shoots with avidity. It is common, 

 but found only outside the forest-region.

Our immature male is similar in plumage to the adult 

 female, but it shews signs, without a direct moult, of 

 assuming the adult male plumage : the light grey of the 

 crown and nape is mottled with black, while several of the 

 tail-feathers are gradually becoming black from their bases 

 downwards.
