Zebra It is an inhabitant of the semi-arid grasslands of Ethiopia and northern Kenya. Grévy's zebra is the rarest species, and is classified as endangered. Although zebra species may have overlapping ranges, they do not interbreed. In captivity, plains zebras have been crossed with mountain zebras. The hybrid foals lacked a dewlap and resembled the plains zebra apart from their larger ears and their hindquarters pattern. Attempts to breed a Grévy's zebra stallion to mountain zebra mares resulted in a high rate of miscarriage. In captivity, crosses between zebras and other (non-zebra) equines have produced several distinct hybrids, including the zebroid,
Plains zebra plains zebra. One of which is its distinctive, high-pitched, contact call (commonly called "barking") heard as "a-"ha", a-"ha", a-"ha"" or "kwa-ha, kaw-ha, ha, ha" (video), also transcribed as "kwahaah", or "oug-ga". The species name "quagga" is derived from the Khoikhoi word for "zebra" and is onomatopoeic for its call. When a predator is sighted, a zebra makes a two-syllable alarm call. A loud snort is made when moving in cover of potential danger. When in contentment, a zebra makes a more drawn-out snort. Males make a short, high-pitched squeal when hurt, and foals emit a drawn-out wail when in distress.
