Rather than being a specific species-by-species guide, this book focuses on introducing the reader to general principles that can be used to understand the moult and age of virtually any bird. With these tools, we can use a bird's moult pattern to say how old the bird is and to understand more about its life-history. Whether you are a beginner watching birds in the garden or a rarity-hunter trying to age a rare vagrant, A Practical Guide to Moult and Ageing will enrich your birding and enhance the data you gather.
