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-chested buzzard-eagle
The black-chested buzzard-eagle is found in mountainous or hilly terrain with sparse vegetation, shrubland or (in the south of its range) "Nothofagus" forest, where it spends a lot of time soaring in thermals and vertical drafts while looking for prey. It requires large territories with suitable habitat, the páramos at the north of its range, for example, while providing the latter, fail to provide the former, and thus it has only been recorded in the largest patches of such habitat, such as Páramo de Frontino. Most common between about and ASL, it rarely ventures into the lowlands.
