Gemsbok Bull courtship circling

gemsbok-bullKgalagadi Transfrontier Park (South Africa side) Gemsbok “courtship circling”, the female gemsbok (not at the picture) is moving away from the bull. Very interersting sighting as most of the time these antilopes are just feeding, resting under a tree or walking through the bush. The bull is trying to move behind the female to sniff her backside. The erected tail (see picture) and the foreleg lifting of the bull (not at this picture) are clear signs his is ready to mount the female.  The bull did finally mount the female but she rejected him by moving away.
