A montage of music and natural sounds from the world’s northernmost freshwater lake in Siberia where you’ll hear the calls of Lapland buntings, oriental golden plovers and ptarmigans. We also visit Ein Bokek Canyon in Israel, where the chirps of graceful warblers compete with the rasping sounds of Tristram’s grackles. Then we head to Dyfed in Wales, where an early morning chorus of chaffinches and wrends is joined by the gentle bleating of sheep and lambs on the hillsides. We end in Tanzania, and the Olduvai Gorge, where calls from slate-coloured bou-bous and yellow-necked francolins combine with the distant braying of donkeys and far-off spotted hyenas.
