Introduced last April, Capybaras Nancy and Sam hit it off immediately at Schönbrunn Zoo in Austria. After a gestation period of about six months, Nancy gave birth to three healthy pups on November 29!

Capybaras are born well-developed and grow quickly. Pups are able to follow behind their mother almost immediately after they are born. Excellent swimmers, these rodents even have webbing between their toes. The three little ones have already ventured into their pool with mom. 

Capybaras are found throughout South America and eat mainly plants. The world's largest rodents, Capybaras can reach a shoulder height of about 1.6 feet (50 cm), and are most closely related to Guinea Pigs.
