A montage of music and natural sounds from ravens on the Norwegian tundra around Tromso; upwelling of cold water currents at night in the deep waters of the Pacific Ocean off the Galapagos islands; a MacGregor’s bowerbird in a New Guinean rainforest displaying its vocal talents to attract a mate, and the splashes of ice laden water moving and lapping on the shore of a river on Hokkaido Island, permeated by distant calls from goldeneye and whooper swans passing overhead.
