Bird Song: Biological Themes and Variations

Extensively updated from the first edition, the main thrust of the book is to suggest that the two main functions of song are attracting a mate and defending territory. It shows how this evolutionary pressure has led to the amazing variety and complexity we see in the songs of different species throughout the world.   Writing primarily for students and researchers in animal behaviour, the authors review over 1,000 scientific papers and reveal how scientists are beginning to unravel and understand how and why birds communicate with the elaborate vocalizations we call song.
