the Birds of Nyamiland. 383 



for we visited Ngamilaud in winter, when its song would 

 seldom be heard. Without its note to guide us, the bird 

 might long escape notice, owing to its habit of skulking 

 in thick cover.

The Black-chested Wreu-Warbler is found throughout the 

 Kalahari. It frequents the patches of open country or low 

 bush, especially around the large salt-pans. It is a very 

 active lively little bird, constantly on the move from one 

 bush to another, and frequently perching on the top. It jerks 

 its long tail up over its back, and utters a stream of clicking 

 notes, like the sound made by the winding of a large fishing- 

 reel.

These Wren-Warblers were particularly plentiful along 

 the edges of the Okavango marshes ; they were always seen 

 in small parties, and upon being disturbed from the grass or 

 rushes would fly up into the trees and there remain hopping 

 about and scolding incessantly at the intruder until he 

 moved away. Both male and female join in this remon- 

 strance ; there is considerable difference in their notes, 

 that of the female being generally shriller.
