Urban environments influence birdsong
Researchers studying the Great Tit, Parus major in 10 European cities have shown that urban environments affect bird songs. In comparison to forest-dwelling tits, urban tits had shorter and faster songs, with an upshift in frequency. This appears to be a result of having to compete with low-frequency environmental noise such as traffic.
The full paper by Hans Slabbekoorn and Ardie den Boer-Visser is available in todays Current Biology (abstract only). You can hear the birdsongs here
