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 bulbul
The black bulbul ("Hypsipetes leucocephalus"), also known as the Himalayan black bulbul or Asian black bulbul, is a member of the bulbul family of passerine birds. It is found in southern Asia from India east to southern China. It is the type species of the genus "Hypsipetes", established by Nicholas Aylward Vigors in the early 1830s. There are a number of subspecies, mostly varying in the shade of the body plumage which ranges from grey to black, and some also occur in white-headed morphs, as also suggested by its specific epithet "leucocephalus", literally "white head". The legs and bill are always rich orange-red.
