[Shop-talk] Bird in shop

[Mullen, Tim (IS)]

Speaking (well typing) of birds in the wrong places...

Over the weekend, I was in my local Wal-Mart - we went in through the
garden area (the semi-covered area where they put the grills, and
outdoor "stuff").  I noticed a screeching/squawking sound that came from
various areas.  Looking closer, I noticed small green speakers around
the roof areas, and the system made the screeching/squawking sounds
"appear" to move around the area.  Thinking about it, I realiesed that
it was predators sounds (i.e. hawks), and it was all a system to scare
away the sparrows that would usually inhabit such an area.  There were
no sparrows in the area so it must work.
