Ornithologist and wildlife sound recordist Seán Ronayne is on a personal mission to record the vocalisations of every bird species in Ireland. For three years, he has travelled across bogs, mountains, remote islands and native woodlands documenting nearly 200 birds, including species on the cusp of extinction. Seán shares his story and his unique, and often surprising, recordings of mimicry, distinct dialects, and birds never recorded in Ireland before. His journey reveals the beauty and importance of sound, and what listening can tell us about the state of our natural world.
