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.
Yellow-tailed black cockatoo
The birds may be found in a variety of habitats including grassy woodland, riparian forest, heathland, subalpine areas, pine plantations, and occasionally in urban areas, as long as there is a plentiful food supply. They have also spread to parts of suburban Sydney, particularly on or near golf courses, pine plantations and parks, such as Centennial Park in the eastern suburbs. It is unclear whether this is adaptive or because of loss of habitat elsewhere. In urban Melbourne, they have been recorded at Yarra Bend Park. The so-called "Black Saturday bushfires" in 2009 appear to have caused sufficient loss of their natural habitat for them to have been sighted in other parts of the urban areas of Melbourne as well.
