Kalahari Desert bird ("Sagittarius serpentarius"), martial eagle ("Polemaetus bellicosus") and other eagles, the giant eagle owl ("Bubo lacteus") and other owls, falcons, goshawks, kestrels, and kites. Other animals include wildebeest, springbok and other antelopes, porcupines ("Hystrix africaeaustralis") and ostriches ("Struthio camelus"). Some of the areas within the Kalahari are seasonal wetlands, such as the Makgadikgadi Pans of Botswana. This area, for example, supports numerous halophilic species, and in the rainy season, tens of thousands of flamingos visit these pans. The biggest threat to wildlife are the fences erected to manage herds of grazing cattle, a practice which also removes the plant cover
Kalahari Desert pans, lakes that are completely dry during the dry season, and maybe for years during droughts, such as in Etosha (Etosha Pan halophytics AT0902) and Makgadikgadi (Zambezian halophytics AT0908). A totally different vegetation is adapted to the perennial fresh water of the Okavango Delta, an ecoregion termed Zambezian flooded grasslands AT0907. The Kalahari is home to many migratory birds and animals. Previously havens for wild animals from elephants to giraffes, and for predators such as lions and cheetahs, the riverbeds are now mostly grazing spots, though leopards and cheetahs can still be found. The area is now heavily grazed and
