This is bogus. We now have these nasty critters here in Georgia. They are NOT migratory. They are feral. They stay year round. They fly in as late as midnight honking and skwalking. They poop everywhere, even while flying. The guy should get a medal for shooting the beast and the guy who told on him should mind his own business. I say kill as many as you can, whenever you can.
A pair of hawks built a nest next to my yard. No more geese problems.
I'm also in GA, and just heard some about 15-20 minutes ago when we were outside seeing a friend off.
