City Birds Trying Out Music Variations

A team of researchers from the University of Leiden in the Netherlands has found that urban species of birds sing short, fast songs rather than the slower melodies of countryside birds. This is an adaptation to counter background noise and increase their chances of finding a mate. The researchers targeted great tits in ten major European cities, including London, Paris, Amsterdam and Prague, and compared them to forest-dwellers. Urban tits consistently experimented with between one and five note calls, while those in forests close to the cities stuck to more normal combinations of two, three and four note tunes. One Rotterdam great tit attempted a 16-note song, which the researchers believe could have been copied from a blue tit. The findings are published in the current issue of journal Current Biology
