A Pied Kingfisher (Cerylerudis) patrols over a hippopotamus (Hippopotamus amphibius) in a drying channel of the Lafupa River in the Kafue National Park, Zambia. As the hippo moves through the water, it makes a bit of a commotion, stirring up bugs and small fish to the surface. The kingfisher knows that with the help of the hippo, those bugs and small fish are easy prey. When the time is right, he will swoop down and take his food directly from the roiled up water.
