In the fourth of our series of bird guides, Brett Westwood is joined by keen birdwatcher Stephen Moss on the north coast of Devon, and with the help of wildlife sound recordist Chris Watson they offer a practical and entertaining guide to identifying many of the birds you're likely to see and hear around Britain's coastline. Each programme focuses on a different habitat, starting with estuaries and birds such as Redshank, Dunlin, Curlew and Knot, then sandy shores and birds including Common and Sandwich Tern; rocky shores (Rock Pipit, Turnstone), sea cliffs (Fulmar, Guillemot, Razorbill), and offshore islands (Puffin, Manx Shearwater and Arctic Tern). Listen to advice on how to recognise birds visually and how to identify them from their calls and songs. After all, often you're more likely to hear a bird than see it!
