Identifying migrants at dusk or at night night becomes a reality with this book, which contains detailed text on flight and contact calls, along with annotated sonograms and QR codes to the calls themselves. Every spring and autumn, millions of birds fly over us to en route to their summer or winter quarters, with these migratory flights often being at night. A profusion of sounds then fills the air, making it possible to collection put a name to these fleeting silhouettes - because the best way to identify these migrants is by sound. Often neglected in traditional identification guides, these calls are described in this book with precision. Annotated sonograms make it possible to visualise, identify and better memorise the flight and contact calls of all European migratory species. * 450 species described, with detailed text, photographs and sonograms. * Text covers essential criteria for effective identification of calls in the field. * Migratory behaviour and where and when to encounter each species is also covered. * Contains QR codes of more than 1,000 downloadable sounds to listen to at home or on your smartphone..
