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 ofi* 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.
