For World Wildlife Conservation Day, we're dropping in to visit a herd of African elephants in the Addo Elephant National Park in South Africa's Eastern Cape province. Established in 1931 to protect a herd of just 11 African elephants, Addo is now the third-largest of 19 national parks in South Africa and provides a safe haven for about 600 of these magnificent creatures, as well as cape buffaloes, various antelope species, lions, hyenas and endangered black rhinos.
