A truly comprehensive multimedia field guide for the avid bird-listener, for quick and easy identification of over 200 birds. This unique Collins Field Guide features two CDs providing audio references for Geoff Sample,s comprehensive list of songs and calls of the common birds of Britain and Northern Europe. With the CDs organised by habitat and the list of birds by species, together they enable the bird watcher to easily match a song or call with the species. Beginning with a scientific overview of the terminology used, the general meanings of bird songs and calls and their various functions as tools for socialising and communicating, the book then takes you through the list of bird species, examining their sounds and their different meanings. With over two hours of digitally recorded sounds and hundreds of species covered, this is an indispensable guide for any dedicated bird fan, leaving you with a far greater understanding of the natural noises that surround us everyday.
