Here's something I learned not long ago. Birds in Central Park (and presumably other urban centers, but the study was done in Central Park), are changing the frequency and other aspects of their song, in order to be heard over traffic, radios, and other forms of human racket. The male birds who are most easily heard are most likely to find mates, so there's a biologicial advantage in doing so.
