changing into the summer plumage ; the upper parts are 
much mottled, the new dark brown feathers contrasting 
strongly with the old rufous brown of the winter plumage. 
This species is not found in the Hinterland.

The winter plumage of this species differs from the 
summer dress in being rufous brown above, brighter on the 
rump and upper tail-coverts ; the chest, sides of body, and 
flanks are washed with pale buff. The specimens killed in 
May are uniform dark brown above, reddish brown on the 
rump and upper tail-coverts. In the winter plumage the 
tails are longer. 
The sexes are alike in measurements.

This species is widely distributed, inhabiting the tall 
elephant-grass. The flight is very straight. 
It is curious that in our large series we did not obtain 
any females. The breeding-season is, no doubt, in May and 
June. In freshly-moulted birds the tails are very long.
