As the water level drops in the Zambezi River, islands in the middle of the stream appear and sand banks are formed. In these sand banks bee-eaters begin to dig out new burrows, working fast before the sun bakes the sand as hard as stone. Living in large flocks helps the bee-eaters keep a close watch on potential predators. A pair of pied kingfishers look for a home in the safety of the bee-eater colony, but they are not welcome. Having arrived too late to find a spot, they will have to go elsewhere.
