Horns Down
Wildlife experts in Africa say they have found it is safer to relocate the critically endangered black rhinoceros upside down, sedated and blindfolded by helicopter rather than by land.
It is sometimes necessary to move rhinos from local overcrowding and to make them less vulnerable to poaching. Their blood oxygen levels are higher when they are upside down, compared to lying on their side on a flatbed truck. Nearly 98% of black rhinos disappeared in the wild after the 1960s, when more than 100,000 roamed the deserts, shrublands and savannas from Kenya to Namibia.
