Sounds of the Earth - April
Slow Radio - A podcast by BBC Radio 3

A montage of music and natural sounds from a dawn chorus on a lakeshore in southeast Sweden, the liquid call of the Australian magpie from a mangrove swamp in Queensland, hippos grunting and splashing in Malawi’s Shire River, and skylarks singing overhead while curlews intone their desolate cries around Deadwater Fell in Northumberland.
