City life drives birds to change their tunes, recent research shows. A new study says that birds living in major cities sing shorter, faster songs that are higher-pitched than those sung by their brethren in the forests. The researchers think that the birds adjust their songs to allow themselves to be heard over the din of the city, especially the low rumble of traffic noise.
