The Guardian News and Media, reports that new research shows songbirds change their tune when they move to cities.Scientists found that great tits adapted to urban living by singing faster, shorter songs that were at a higher frequency than their forest-dwelling cousins.
Hans Slabbekoorn of Leiden University recorded the songs of great tits in 10 European cities, including London, Prague, Paris and Amsterdam. He then compared the songs with birds of the same species in nearby forests.
The results, published in the journal Current Biology, showed that songs important in attracting mates and defending territory were markedly different in the urban setting.
