Never let them see you coming. That’s the unofficial motto of all predators. But the tactic didn’t work for this big cat when he tried to bring down an antelope apparently busy in a fight with another male.

The red lechwe had just spent ten minutes locking horns with a rival in the Okavango Delta area of Botswana when the leopard, judging the moment was right to pick off a weakened target, pounced.

Thomas Nkwazi took these photos while on a morning drive. ‘At one point the antelope was running with the leopard hanging under its throat before it dropped it down,’ he said. ‘The lechwe was too big and strong, and after the battle the leopard was limping on its left front leg. The antelope had some scratches and a bit of a cut on the shoulder, which I think was from the fight with the other lechwe.’
