Zebras have excellent eyesight.Like most ungulates the zebra has its eyes on the sides of its head, giving it a wide field of view.Zebras also have night vision, although not as advanced as that of most of their predators, but their hearing compensates.Zebras have great hearing, and tend to have larger, rounder ears than horses.Like horses and other ungulates, zebra can turn their ears in almost any direction.In addition to eyesight and hearing, zebra have an acute sense of smell and taste.Like most members of the horse family, zebras are highly sociable.Mountain zebras and Plains zebras live in groups, known as 'harems', consisting of one stallion with up to six mares and their foals.When attacked by packs of hyenas or wild dogs, a zebra group will huddle together with the foals in the middle while the stallion tries to ward them off.Unlike the other zebra species, Grevy's zebras do not have permanent social bonds.However like the other two zebra species, bachelor male zebras will organize in groups.Like horses, zebras sleep standing up and only sleep when neighbors are around to warn them of predators.Zebras communicate with each other with high pitched barks and whinnying.When a zebra is in a calm, tense or friendly mood, its ears stand erect.When it is frightened, its ears are pushed forward.When angry, the ears are pulled backward.When surveying an area for predators, zebras will stand in an alert posture; with ears erect, head held high, and staring.When a predator is spotted or sensed, a zebra will bark (or bray) loudly.Food and foraging
Zebras are very adaptable grazers.They feed mainly on grasses but will also eat shrubs, herbs, twigs, leaves and bark.Their well adapted digestive system allows them to subsist on diets of lower nutritional quality than that necessary for herbivores.Reproduction
Like most animal species, female zebras mature earlier than the males and a mare may have her first foal by the age of three.Males are not able to breed until the age of five or six.Like horses, zebras are able to stand, walk and suckle shortly after they're born.Plains and Mountain zebra foals are protected by their mother as well as the head stallion and the other mares in their group.Grevy's zebra groups often disband after a few months.Attempts have been made to train zebras for riding since they have better resistance than horses to African diseases.However most of these attempts failed, due to the zebra's more unpredictable nature and tendency to panic under stress.Lord Rothschild with his famed zebra carriage (Equus burchelli), which he frequently drove through London.In England, the zoological collector Lord Rothschild frequently used zebras to draw a carriage.In the mid 1800s Governor George Grey imported zebras to New Zealand from his previous posting in South Africa, and used them to pull his carriage on his privately owned Kawau Island.Captain Horace Hayes, in "Points of the Horse" (circa 1899) compared the usefulness of different zebra species.Hayes saddled and bridled a Mountain zebra in less than one hour, but was unable to give it a "mouth" during the two days it was in his possession.He noted that the zebra's neck was so stiff and strong that he was unable to bend it in any direction.Conservation
Modern man have had great impact on the zebra population since the 19th century.Zebras were, and still are, hunted mainly for their skins.The Cape mountain zebra was hunted to near extinction with less than 100 individuals by the 1930s.Both Mountain zebra subspecies are currently protected in national parks but are still endangered.The Grevy's zebra is also endangered.Plains zebras are much more numerous and have a healthy population.One subspecies, the quagga, is now extinct.How do a zebra's stripes act as camouflage?.How the zebra got its stripes: biting flies as selective agents in the evolution of zebra colouration.The Behavior Guide to African Mammals, Including Hoofed Mammals, Carnivores, Primates.Natural History Of Zebras" September 1976."Points of the Horse" (circa 1899)
