We use names so often that few of us ever pause to wonder about their origins. What do they mean? And where did they come from? From the common starling to the many-coloured rush tyrant, the names we have given to birds are some of the most vivid and evocative words in the English language. They can carry whole stories - of arctic expeditions, pitched battles between rival ornithologists or touching romantic gestures. Through fascinating encounters with the bird kingdom and the rich cast of characters responsible for coming up with their names, in Mrs Moreau's Warbler Stephen Moss shows how these words reveal as much about ourselves and our relationship with the natural world as about the creatures they describe.
