I remember hearing or reading somewhere that black and white rhinos have very different temperaments, which is why white rhinos can be mixed with other species while black rhinos need their own enclosure. Is this actually true? My main experience with African rhinos has been in Midwestern zoos like Saint Louis, Indianapolis, and the Chicago zoos; in these zoos, black (3 zoos) and white (1 zoo) are all given their own enclosure, except for a few birds at Saint Louis that stay in a separate area within the enclosure. Does anyone know of black rhinos being mixed with other species, or how common it actually is to mix white rhinos in rather than keeping them separate? And is there actually a difference in their temperaments that affects husbandry?
