The Zoo

There is huge excitement at the Amur tiger habitat as first-time mother Tundra gets ready to give birth, while a young male western lowland gorilla arrives at the zoo.

A western lowland gorilla is accepted into the rest of the zoo's troop, leading to some exciting news. Tiger cubs and their mother explore the outdoor habitat for the first time.

Gerry travels to India to witness the zoo's elephant conservation projects in action. A giraffe gives birth, and four young Indian star tortoises are moved into a larger habitat.

An elderly rhino recovering from a skin condition needs additional treatment, Gerry meets an Asian elephant in India, and the Chilean flamingo flock begin to lay eggs.

A heatwave poses a unique set of challenges for the zookeepers, who provide ice-pops for the primates and tigers and a mud bath for the young elephant calves.

Two of the sea lions prepare to give birth, and the team has to go through some very special training to transport an Asian bull elephant to another zoo.

Three sea lion pups are ready to fully explore their underwater habitat, and an Asian bull elephant needs a clean bill of health before being transferred to a French zoo.
