Topi on alert as a cheetah walks by. We were tracking a pair of cheetah siblings as they prowled the grasslands of Masai Mara, looking for food. They crossed a few fields and one of them was full of these grazing Topi. This was one of my favorite compositions that included a predator low in the grass, a large number of potential prey and the stunning backdrop of the lone Balanites tree and the African savanna.
