Leopard resting on tree branches, Serengeti National Park, Tanzania

The leopard (Panthera pardus) is known for its ability in climbing, and it has been observed resting on tree branches during the day and descending from trees headfirst. It is a powerful swimmer, although, not as strong as some other big cats, such as the tiger. The leopard is also very agile, and can run over sixty kilometers an hour, leap over six metres and jump up to three metres vertically. The leopard is primarily a nocturnal creature, and many of its operations are done by night. However, there have been recorded instances of leopards hunting during the light, especially when the sky is overcast. It spends much of its day resting and sleeping, up in the branches of trees, underneath rocks or in the grass. This photograph was taken when Eliot Elisofon was on assignment for American Broadcasting Company and traveled to Africa from June 1966 to early August 1966.
