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.

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.

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.
