Danish ornithologists say that birds, especially Starlings, have begun incorporating the sound of a ringing cellular phone into their own songs. So far, reports of wireless warbling have been restricted to Copenhagen, where birds seem to favor Nokia's classic ring tone.
Birds imitating sounds produced by technology is nothing new.
They choose simple tunes to reproduce. The standard ring tone on a phone usually comprises any combination of nine tones. And the tunes themselves don't typically contain harmonies, which are made by playing multiple musical tones at the same time. Usually, birds copy what they hear the most. Birds in rural areas have added the sound of horses whinnying, lawn mowers and even chainsaws to their repertoires.
