The plains zebra live in small family groups called “harems.” These groups consist of one stallion, several mares, and their offspring. Harems generally remain together for months or even years, making it an incredibly stable family unit. The plain zebra has at least 6 different vocal calls. A two-syllable call is used to alert herd members to predators while snorts indicate happiness. They also use facial expressions to communicate. When greeting each other, they will stick their ears up and push their faces forward. When feeling threatened, they will press their ears against their heads.
