The only CD audio guide to the Warblers of Britain and Europe, one of the hardest groups of birds to identify -- often the only way to tell them apart is by their songs and calls. Possibly the most difficult group of birds to identify, often known as 'little brown jobs' as they are so difficult to distinguish visually, many warblers can only be identified positively by their songs and calls. The three CDs contained in this book provide high quality recordings of all the Warbler species that occur in Britain and Europe, and the accompanying book explains how to interpret the sounds and make an accurate identification. Aimed at keen birders, and those who want to find out more about this intriguing family, this book will doubtless become an essential tool for warbler identification.
