Ornithologist Seán Ronayne is on a mission to record the sounds of every bird species in Ireland – around 200 in total. Often accompanied by his partner, Alba, he travels to the country’s most beautiful and remote locations to capture some of the rarest birds. On this trip, we get to know Seán better, as his special sensitivity to sound is both a strength and a challenge. His inspiring journey reveals the beauty and significance of sound and how listening can tell us more about the state of nature than we ever imagined.
