It was early morning, and I was heading for Lake Ndutu, in the southern Serengeti, to look for animals. A wildebeest had died at the water's edge, and lots of hyenas were feeding on it.

Then one hyena cut straight across the water carrying a leg from the carcass, running off to hide it and eat later. It's one of the most beautiful sightings I've ever had. Out here, as they say, the strongest takes the food, and for the weaker ones it's hard.
