Disc 1. Orangutans - The High Society 1 x 54:00 min We visit the exceptional Ganung Palung Reserve in Borneo, where we follow individual orangutans at key stages in their life to look at the trials they face and the kind of decisions they make in this taxing environment. Like us, orangutans grow and reproduce slowly. We observe the infant and young orangutans and also study their social structure and survival tactics. Disc 2. Gorillas - Tender Giants 1 x 54:00 min Early explorers in central Africa brought back wild tales of gorillas as half-man, half-monster. We know better now. But the real lives of gorillas remain elusive even today. To see how these tender giants really live, we travel into the dark heart of the Congo Basin. It is the story of a remarkable man and his fight to protect one of the rarest animals on earth. Disc 3. Great Siberian Grizzly 1 x 51:00 min The Kamchatka Sanctuary in the Russian tundra is home to the grizzly bears of the Kronotsky Reserve. This programme follows a mother and her three cubs in their yearly cycle. From their six months in hibernation under the snow, to the yearly salmon migration that draws countless bears to the river beds each spring, it is a story of survival.
