Founded in 1927, the 64-acre (26 ha) Rio Grande Zoo, located in Albuquerque, New Mexico, is a facility of the Albuquerque Biological Park. After a branding change, the Albuquerque Biological Park dropped "Rio Grande" from the name; the zoo is now called ABQ BioPark Zoo. Some of the most popular of the over 200 species are seals and sea lions, chimpanzees, gorillas, orangutans, elephants, polar bears, giraffes, hippos, camels, tamarins, koalas, Mexican wolves, cougars, monkeys, jaguars, zebras, and rhinos.
