Thirty five year-old ornithologist Seán Ronayne from Cobh, Co Cork has an acute ear and a passion for the natural world. After compiling a list of 195 ‘regularly occurring’ bird species in Ireland, he sets out to record each one. But what begins as a recreational personal project transforms into an urgent environmental mission. Seán’s recordings – many the first of their kind – reveal stark realities of our biodiversity and climate crises, and provide a poetic record of a vanishing, vital part of our world.
