For a small fish like a stickelback, a speeding flash of blue, red and white diving into the water is the last thing you’d want to see. Wildlife photographer Paul Sawer captured these dramatic images of a small blue kingfisher diving into the water. It eventually came up with a small fish in its bill. Then it flew back to its perch and whacked the fish on it. This is the usual behaviour of kingfishers, and they do this so the spines off the fish so it can swallow it whole.
