It was near the end of an evening game drive when I made this image. We didn't have any significant photographic opportunities that evening but after encountering a Secretary Bird perched atop its nest, we paused to photograph for a few moments. Though I also had the 500 with me, I chose to work with the 70-200 instead, opting to get a wider view of the scene including the nest and some of the fluffy clouds above.
