Cisticola natalensis
The croaking cisticola is the largest cisticola in southern Africa. It is more robust that the others and has a much thicker bill. It can be found in grasslands and grassy savanna on the east coast of South Africa, and in much of Mozambique and Zimbabwe.
We first set our eyes on this heavy-billed cisticola in March 2011 while on a game drive with Matthew and Sam Spencer in the Hluhluwe Game Reserve, northern KwaZulu Natal.
