The Zoo: San Diego

A baby klipspringer is born on one of the coldest nights of the season and is miraculously nursed back to health; the California condor team at the Safari Park goes to unbelievable lengths to save this highly endangered species.

Hunter the koala is ready for a mate; Jaws the Galápagos tortoise isn't feeling well and the zoo staff works to bring him out of his shell; the Safari Park has two baby giraffe calves that need to be hand-reared simultaneously.

There will be no peace in the world for the hamadryas baboons until Impo finds his mate, but the San Diego Zoo keepers have a plan; two young cheetah cubs are training to become animal ambassadors with the help of their experienced canine guide.

Safari Park keepers prepare Aria the rambunctious black rhino for her new life on the open African Plains exhibit; zoo staff cares for 15-year-old legend M'bari the lion and his mate, Etosha; a vulture chick learns to eat from a surrogate puppet.

The Zoo says goodbye to beloved pandas Bai-Yun and Xiao Liwu as mother and cub prepare to return to China; Tembo the retired Hollywood elephant tries traditional Chinese medicine for her arthritis; The Butterfly Jungle gets colored for the season.

After six years away, Mek the tiger returns to the Zoo; two shy tree kangaroos, Spike and Polly, meet for the first time; with the Children's Zoo under construction, the keepers have to move over 100 animals, including a herd of reluctant goats.
