Olive-tree warbler, Hippolais olivetorum, at Mkuze Game Reserve,

The olive-tree warbler leaves its breeding ground in southern Europe every year, and flies to southern Africa for the northern winter. They are fairly common here, but not very easy to find as they are secretive and don't usually call. A famous location for them is in the dense acacia by the airstrip at Mkuze where these photos were taken.
