Geese and swans are very mean animals.
Taste good too.
I remember one time to LOL about. I went to play golf with an old H.S. friend a few years back. The T-off spo was occupied by a couple of geese. I chased them off and they started to get really mad. Of course, if they got close, the golf club wins !
They also learned who were the repeat visitors whom we welcomed. How they could tell just by the car, we never could figure out.
