Zebras live in social groups. The leader of the group is the stallion. The females that live in the group are called fillies. A female zebra can have her first foal by the age of three, and can give birth to a foal every twelve months. Foals are brown in color when they are born and are close to their mothers, but the male foal is also close to its father. The foals leave the group anytime from the time they reach 1 year old.
Zebras sleep standing up like horses. They communicate by barking, snorting or whinnying. A zebra's ears communicate if it is feeling calm or tense. If its ears are standing straight up, it is feeling calm. When the zebra's ears are pushed forward, it is feeling tense or frightened.
Zebras like to associate with other animals such as baboons, giraffes, impala and kudu, however, the most common association is between the zebra and the wildebeest. Unlike their closest relatives, horses and donkeys, zebras have not been truly domesticated.
