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-faced antbird
The black-faced antbird is found in a wide range of about 4,800,000 km across the Amazon basin in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is tropical moist lowland and foothill evergreen forest, generally below 1000 m. It prefers densely vegetated areas in light gaps (such as tree falls) in "terra firme" forest.
