Black wildebeest
Where it lives alongside the blue wildebeest, the two species can hybridise, and this is regarded as a potential threat to the maintenance of the species. The black wildebeest was once very numerous and was present in Southern Africa in vast herds, but by the end of the 19th century, it had nearly been hunted to extinction and fewer than 600 animals remained. A small number of individuals was still present in game reserves and at zoos, and from these, the population was rescued.
Black eagle
The black eagle breeds in tropical and subtropical Asia. Race "perniger" (Hodgson, 1836) is found in the Himalayan foothills west through Nepal into the Indian states of Himachal Pradesh and Jammu & Kashmir, and in the forests of the Eastern and Western Ghats in peninsular India and Sri Lanka. The bird's westernmost extent is from Gujarat, especially in the forested areas in southern and eastern Gujarat. The species also extends into the Aravalli range of northwestern India. The nominate race "malaiensis" (Temminck, 1822) is found in Burma, southern China (Yunnan, Fujian) and Taiwan, into Southeast Asia. They are generally residents and no migrations have been observed. In a study in southern India, it was found to favour forests with good forest cover and was absent from areas where the cover was less than 50%.
