Black wildebeest
Features necessary for defending a territory, such as the horns and broad-based skull of the modern black wildebeest, have been found in their fossil ancestors. The earliest known fossil remains are in sedimentary rock in Cornelia in the Orange Free State and date back about 800,000 years. Fossils have also been reported from the Vaal River deposits, though whether or not they are as ancient as those found in Cornelia is unclear. Horns of the black wildebeest have been found in sand dunes near Hermanus in South Africa. This is far beyond the recorded range of the species and it has been suggested that these animals may have migrated to that region from the Karoo.
Black sparrowhawk
Both subspecies are only found in parts of Africa that are south of the Sahara desert; "A. m. temminckii" inhabit much of the northwest section such as Senegal, the Democratic Republic of the Congo, and Central African Republic, while "A. m. melanoleucus" can be found starting from the northeast section down to South Africa. They naturally inhabit patches of forests, rich woodlands and riverine strips extending into dry bush areas. They can be found in many areas as long as they have large trees, including mangroves in coastal Kenya. Especially in southern Africa, black sparrowhawks have adapted to stands of the non-indigenous eucalyptus, poplar, and pine, all of which are grown commercially and are able to grow up to taller than native trees. Their adaptability to secondary forests and cultivations (they are not uncommon around homesteads now) is one of the reasons why they are not as greatly impacted by deforestation as many African forest birds and may actually increase populations where such stands have been placed in otherwise open country. They can be found in elevations from sea-level to .
