I was driving back to a wilderness camp in the Kruger National Park when I came around the corner and saw something that amazed me straight away. Standing up against a tree trunk with its backside was a zebra, swinging from side to side, enjoying a good scratch. I found it really funny to watch the zebra swinging its backside about, but the reason I was so amazed is that one normally does not see zebras scratching themselves against posts or trees to get rid of itches caused by pesky insects. Animals with no or little hair normally shows this behaviour, such as elephants, rhinos and warthogs. Animals with hair or a coat such as zebra, giraffe and most antelope species rely on a bird called the oxpecker that combs through their hair to feed on ticks and other insects that causes the itching. I assume on this day there were no oxpecker birds around and the zebra decided that the nearest tree will have to do. I was very pleased with this very quick and unexpected moment.
