A litter of six Chacoan Peccary pups was born at San Francisco Zoo in early November. They are busy playing and exploring their outdoor habitat, in the company of the zoo's adult herd. The little ones love to leap and run in circles, an adorable behavior sometimes referred to as 'frisky hopping'. 

Chacoan Peccaries are an endangered species of New World pig, found in the dry shrub habitats of Paraguay, Bolivia and Argentina. They are threatened by loss of habitat and illegal hunting. Social animals, they live together in territorial groups, often extended families. They eat plants, including cacti, which they roll along the ground with their snouts to remove the thorns.
