Quinton Rochat a game ranger, calls for help as he has just tranquilized two rhinos from a helicopter on October 2, 2003 in Hluhluwe-iMfolozi national park in Natal, South Africa. Mr. Quinton works for Kwa Zulu Natal Wildlife and the rhinos were bought on the yearly wildlife auction in June by an international buyer representing Kolm?rden, a Swedish Zoo. The park has a surplus of animals and some are sold each year to finance wildlife conservation and to stop poaching. .©Per-Anders Pettersson/iAfrika Photos.
