Black wildebeest
Black wildebeest act as hosts to a number of external and internal parasites. A study of the animal in Karroid Mountainveld (Eastern Cape Province, South Africa) revealed the presence of all the larval stages of the nasal bot flies "Oestrus variolosus" and "Gedoelstia hässleri". The first instar larvae of "G. hässleri" were found in large numbers on the dura mater of wildebeest calves, specially between June and August, and these later migrated to the nasal passages. Repeated outbreaks of mange (scab) have led to large-scale extinctions. The first study of the protozoa in blue and black wildebeest showed the presence of 23 protozoan species in the rumen, with "Diplodinium bubalidis" and "Ostracodinium damaliscus" common in all the animals.
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 .
