Blue wildebeest
This species of wildebeest seems to have evolved around 2.5 million years ago. The black wildebeest is believed to have diverged from the blue wildebeest to become a distinct species around a million years ago, in the mid- to late Pleistocene. Fossil evidence suggests that blue wildebeest were quite common in the Cradle of Humankind in the past. Apart from eastern Africa, fossils are commonly found in Elandsfontein, Cornelia, and Florisbad.
Black-cheeked lovebird
The black-cheeked lovebird inhabits deciduous woodland, where permanent supplies of surface water exist, as it needs daily access to water. In the dry season, these birds may congregate in large flocks of up to 800 or more. They are found in Zambia and may occur in Zimbabwe, Botswana and Nambia. 
It is listed as a vulnerable species its population is in decline due to continuous habitat loss. This is due to gradual desiccation of water bodies, causing drought,farming practices, hunting and trapping, fishing, logging and dieseses. There are currently only between 2500 and 9999 mature individuals. However, they occur in nature reserves and there is an action plan in place to help them.
