Recently Ive been watching a series called African Wild, that focused on different regions and groups of African wildlife and it made me wonder about why certain common animals in Africa aren't usually/often displayed in zoos. With African Savanna themed exhibits being so popular it made me wonder why Ive mostly only seen the same old zebras, impala, and ostriches and not more interesting hoofstock. With species like Water Buffalo, Wildebeest, Nilgai, Greater kudu, & Black wildebeest all being fairly common why are animals like these not mixed in with the average savanna exhibits we see? Are they aggressive toward other species? Do they need extremely larger areas? Are they just harder to get in zoos? Have I just not seen enough zoos? What are other common animals you usually don't see? Are what are other animals that are difficult to display for facilities? Ive heard that Bonobos aren't usually displayed for not just being rare but because they are so sexual.
