Watch Spy in the Wild

The Spy Creatures travel to the lands of ice and snow beyond the Arctic and Antarctic circles. From penguin chicks to elephant seals, wolf cubs to polar bears, this episode showcases the hardiest and most charismatic animals in the polar world.

The Spy Creatures explore the islands of the Southern Seas. In these isolated places, far from the mainland, some of the most unique animals on earth have evolved. On the Galapagos Islands, Spy Iguana joins marine iguanas as they bask on ancient lava, before cliff-diving into the sea below. Lavacam films battling females as they fight over the best nesting spots and Spy Iguana joins them as they comically spray snot, a technique that removes sea salt from their bodies. On Christmas Island, red crabs emerge from their burrows following the monsoon rains. Spy Crab walks with them as they unite as an army and march to the sea. On the way, they tackle barriers that in the past they would never have encountered: high metal fences and busy roads. When they finally arrive, they perform a victory dance that shakes their thousands of eggs into the ocean. On Kangaroo Island, Spy Koala films some of the most extraordinary koala behavior ever recorded, capturing the action-packed breeding behavior of these normally slow-moving animals. It even captures males fighting in the treetops - a surprisingly noisy and aggressive affair! Off the tip of South Africa lies Seal island, home to 60,000 cape fur seals who come ashore to raise their pups. Spy Seal Pup is right in their midst as they quarrel for space before leaping into the sea to play. Rottnest Island, off the south west coast of Australia, is home to one of the most photogenic creatures in the world - the quokka. These small furry marsupials are relatives of kangaroos and wallabies, and Spy Quokka is here to investigate how these cute animals raise their young. The infamous Komodo Island is the setting for one of the most dramatic Spy scenes yet. It's the breeding season for the massive Komodo dragons and the three-meter-long males are on the hunt for females. In scenes reminiscent of Jurassic Park, males fight over this female until one of the huge reptiles is pinned to the ground. All the while, Spy Pig has been filming.

The Spy Creatures travel to the temperate lands north of the tropics where life is governed by the rhythm of the seasons. In the spectacular snow-covered mountains of Japan, Spy Macaque records how snow monkeys bathe and socialize at steaming hot thermal pools. In the cool mountains of Mexico, Spy Hummingbird takes us into the heart of what must be the world's most beautiful natural gathering as billions of spectacular monarch butterflies overwinter.

Our Spy Creatures investigate the extraordinary wildlife that thrives in the tropics and the events and gatherings that happen across the year. For the first time, our Spy Creatures record how gorillas sing when they are enjoying their meals, and in a comical moment they experience the noisy after-effects of their vegetarian diet. In Brazil, Spy Jaguar Cub explores a beautiful gathering of water birds, capybara and caiman and joins Spy Caiman to film a feeding frenzy as its wild counterparts go fishing. In Costa Rica, Spy Turtle and Spy Vulture gain an insider's view of the spectacular turtle arribada as thousands jostle for a place on the beach to lay their eggs. In Zambia, Spy Hippo takes us into the heart of a hippo pod, and is too close for comfort as it films a dramatic fight. Spy Dolphin and a host of other Spy Creatures, such as Spy Monkey, Spy Sloth and Spy Macaw, take us into the mysterious world of the Amazon's flooded forest, and in northern Australia, Spy Bat becomes immersed in a nursery of little red flying foxes and joins them on the wing as they risk getting snapped up by hungry fresh water crocodiles. Spy Orangutan returns to Borneo to investigate the extraordinary bulbous-nosed proboscis monkey and some curious orangutans. In incredible scenes, Spy Baby Elephant uncovers the secret world of pygmy forest elephants, and in a thrilling finale, Spy Penguin and Spy Seal join Humboldt penguins as they bravely navigate thousands of angry sea lions as they try to return to their hungry chicks.
