I'm an avid duck hunter. When the waterfowl migrate, they stay ahead of the cold fronts. You can generally tell cold weather is approaching when geese and ducks are on every puddle of water you drive by. This week should start peak migration of waterfowl here in Ohio. Skim ice is growing on every pond with these evening temps dipping. I get pumped up when the birds are in full swing. Good shooting for us waterfowlers, and knowing that when their gone south ice is around the corner. This morning I limited out on ducks with my Dad. So I predict the next two weeks will be it for ducks and we will be dragging our shantys to limit out on fish around Christmas.
