Bird from Namibia (1 Viewer)

Hello,
a big crop of a small bird seen last month in Namibia, Tsumeb.
I have no idea of the species of that bird.
I hope somebody will help me !

Considering range and also the time of year I think it might be a lesser swamp warbler. Though I’m not sure if this image is enough for a definite answer.

Thanks Bewick for your answer. It is true the quality of the picture and the position of the bird makes the identification difficult. Any other opinion???
