NH.
Speaking of keeping birds away, I was in Cabo San Lucas, MX in April. The resort paid a guy to walk through the pool/outdoor restaurant areas with his Hawk severasl times a day.
Just this guy walking around with the hawk kept all the smaller birds and iguanas away. If not they said that the little birds would land right on your table/lounge chair and steal french fries, etc right off your plate.
It was pretty cool. I had never seen anything like that before. The bird handler said he went between a few different resorts along the coast.
