I took me a while, yesterday, before I noticed where the birds were. On the top floor of an inner-city car park, one might indeed expect real birds to tweet. So just before we stepped into the elevator, I went back to see where those birds were. The garage was not a closed building, but had several large openings that showed that the sun was shining brightly on this October Saturday afternoon. However, there were no birds.
Just when I turned back towards the little hall with the elevators, I noticed the loudspeaker mounted against the car park wall. There were the birds. I was a bit disappointed at first, but then I looked at the bright side of this initiative. Rather than making a lot of music sound through the speakers, this garage prefers to relax people with the singing of birds.
Great idea!
