Today is International Dawn Chorus Day.
The Gaurdian newspaper reported that songbirds imitate mobile phone ring-tone back in 2003. Excerpt:
“Starlings have begun to imitate the ring tones of mobile phones. Researchers at the Royal Society for the Protection of Birds (RSPB), and in Denmark, had noticed over the past year that the birds are adapting their mating calls.
Starlings, well known as mimics, are members of the same family as the mynah bird. But until now they have limited their mimicry to that of other bird songs or, in some cases, shepherds whistling at sheep dogs. “The birds incorporate the sounds because it is believed that the richer the sound, the variety of tones it has, makes the male more attractive to the female,” says a spokesperson for the RSPB. ”
The phenomena was reported in Australia in 2001: Wierd news
Nature imitates technology, technology then imitates nature. As ringtone providers include Birdsongs in their repetoire.
