This is a Tinkling Cisticola also known as a Levaillant's Cisticola, (Cisticola tinniens), Hermanus, Western Cape, South Africa.
Shot this at the vlei Sat morning.
Thanks Francois for the ID confirmation ...
Only 3 Cisticolas occure in part of the Western Cape namely Zitting, Levaillant's and Grey-backed (and Nedidicky (NEDDICKY) which appears with the Cisticolas in the field guides).
I am sure yours is a Levaillant's Cisticola.
Great shot by the way"
Also Hedri for the ID
