We can hear birdsong anywhere, whether we live in the city or in the country. Without the musical backdrop provided by our feathered friends, our gardens, parks, woods, fields and wetlands would be relatively silent - and much the poorer for it. Often we hear their calls, but cannot see the birds making them. This easy-to-use package of book and CD offers insight into the secret world of birds. The CD features 96 bird calls of species commonly found in a variety of habitats across Britain and the rest of Europe. Each audio track is numbered to coincide with the guide for quick reference. The book also presents full-colour photographs of the birds and interesting text about their habits, feeding and nesting routines, as well as their calls. Invaluable for birders of all ages and abilities, this CD and book offer an ideal way to increase your knowledge of bird identification and help to understand their behaviour. It is a guide for birdwatchers of all ages and abilities, from expert to beginner. It is ideal for home use or to take on birding trips. It will appeal to travellers, wildlife enthusiasts, students and specialists alike.
