Watch on SFlix. Living in the depths of the New Guinean Rainforest are birds of unimaginable colour and beauty. When Europeans first saw the plumes of these fabulous creatures they believed they must be from heaven and called them Birds of Paradise. David Attenborough introduces a team of New Guinean naturalists as they embark on a gruelling expedition to try and film ten birds of paradise deep in the heart of the rainforest.
