Pigs: Suidae

Pigs live in altitudes of up to 13,000 feet (4,000 meters) and choose their habitats depending upon the availability of food, weather conditions, and the predator, animals that hunt pigs for food, population. African pigs occupy small territories or home ranges while other pigs tend to roam in search of better feeding grounds. Regardless of species, pigs build nests out of vegetation for protection from weather as well as for resting. Warthogs do not build their own nests but use those belonging to aardvarks. Home ranges must have sources of shade as well as water and mud holes. These three characteristics are important because some pigs do not have sweat glands to cool their bodies.
