Calf mortality. Attacks by hyenas on rhino calves in the Salient have been observed at the lodges' salt-licks for many years, although no successful attack has ever been reported. The high percentage of calves showing scars presumably inflicted by hyenas point to predation as a potential factor of infant mortality in the ANP. However, six out of eight known rhino cows regularly visiting the Ark salt-lick were accompanied by their calves. This gives a cow-calf ratio of 1:0.75 which is comparatively high; cow-calf ratios at Ngorongoro and Olduvai are 1:0.72 and 1:0.79 respectively.
