Identifying Migratory Birds by Sound in Britain and Europe

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 fills the air, making it possible to 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.
