For four decades, Penny has walked beside the river at Oundle – a lovely but little-known part of England where where Clark Gable and thousands of American airmen were stationed during World War II, and where bandleader Glenn Miller performed his final airfield concert before going missing in action. For a whole year, Penny gave the waterway all the time it asked for. The more attention he gave, the more he saw the kingfishers and heard their high whistling calls. Call of the Kingfisher relates a year by the river, the author’s experiences there and the people he meets. Other strands weave around the feathered protagonist: explorations of history and landscape, from Roman and Bronze Age sites to watermills and centuries-old stone churches; homages to naturalists who lived nearby; forest dawns and dusks listening to the precious song of nightingales. But the background tapestry is the riverbank’s sights and sounds, and its greens and browns, shot through with the blue and orange threads of a kingfisher’s glowing feathers. As a composer and wildlife recordist, Penny has a deep interest in sounds in the natural environment. He uses the local landscape and wildlife sounds as inspiration, and brings fresh insights into countryside sounds. The book includes access to an hour of high-quality birdsong recordings made alongside the River Nene – audio soundbites of nature’s riches, from kingfishers and nightingales to owls and cuckoos. This is a book about the things that can be seen and heard when we approach nature with patience and curiosity. It celebrates people who have used that focus to help preserve wildlife and pass on their knowledge to future generations. Above all, Call of the Kingfisher serves as a call to appreciate what we’ve got, wherever we are, and to use our ears as much as our eyes when we experience the natural world.
