Birds imitate mobile phone ring tones

Birds imitate mobile phone ring tones:
"Birds have learnt to imitate the ring tones of the omnipresent mobile phones, say German ornithologists.

'The birds have an uncanny ability to mimic these ring tones. This has picked up in tandem with the boom in mobile phone ownership,' Richard Schneider of the NABU bird conservation centre near the university city of Tuebingen here said."
