WILDERNESS SONGS (HB)

From blue whales that can converse between global hemispheres, the whistling of the Northern Lights and a volcanic explosion heard over a twelfth of the Earth’s surface, to elephants that use individual names for different members of their herds, wildlife filmmaker Justin Anderson uncovers some of the most unusual natural sounds on the planet. Along the way, he explores the latest research into how animals communicate, how recordings can be used in conservation, and the soundscapes of forests, mountains and oceans.
