Song Overproduction, Song Matching and Selective Attrition during Development
The bewildering diversity among bird species in the number of songs that males sing and in the degree of geographic variation in song structure have long intrigued biologists (Krebs and Kroodsma 1980). This diversity in part is a consequence of song learning. At some time in their lives, male birds memorise adult song models that serve to guide the young male’s own song efforts (Thorpe 1958; Konishi 1965; Marier 1970).
