Swallow and starling, puffin and peregrine, blue tit and blackcap. We use these names so often that few of us ever pause to wonder about their origins. What do they mean? Where did they come from? And who created them? The words we use to name birds are some of the most lyrical and evocative in the English language. They also tell incredible stories: of epic expeditions, fierce battles between rival ornithologists, momentous historical events and touching romantic gestures. Moss is one of our most treasured naturalists and broadcasters.
