I used to go to the same food court nearly everyday for lunch during work. They had birds wander in, little sparrows, that would peck at the crumbs. Not that many of them if any at all.

They deployed a constant sweeping high pitched noise emitter to combat the birds and it's impossible to be in the area now. I just can't imagine how they're legal or even sensible.

I wonder if perhaps it wasn't a ploy to get the court to slow down and get the tenants to leave so they can redevelop it. It's been a local institution for some time.
