Those of us who love to look for wild animals in Africa are always conscious of that fact. We know that leopards see us many, many times more often than we see them. I have placed the leopard in the cleft of the granite cliff in Namibia. Often, so that they cannot be easily seen, leopards will lower their noses so that they are concealed and the head shape is less obvious. In the big game areas of Africa, viewing lions is not a challenge.
Cheetahs are scarce, leopards are secretive, but lions are right out in the open.
Often, the flick of a tail is the only sign of life. It is the lions that you cannot see that the prey should fear. A lion can hide in grass scarcely higher than a foot. Their attack technique is a charge from an ambush. The moment before they charge, they are crouched very low, both hind feet on the ground and both eyes on the subject of the attack.
