Hi Anthony-when I first hunted with David Roy, which was around 2000, there was no snow goose hunting in the area. There was an occasional flock here and there, but not anything you would go there to hunt for. I know in the last several years they were in that area(Thousand Islands) big time, and he hunted them in the fall. Snow goose migration patterns seem to constantly change. I think I've mentioned it here before, but along Delaware Bay they would stage for the northward migration starting in late December from Maurice River cove west to Salem NJ. I would hunt them a couple of times in late January or February(in the marsh, not fields). The last few years the numbers have steadily dwindled, and I haven't been for 4-5 years now, mostly for other reasons. I would have tried once this year but again, the numbers just weren't here. They seem to stay further south on the eastern shore of Maryland and Virginia now, and then head up through PA and NY late winter. I don't think anybody knows why.
My hunting for snows consisted of using about a dozen floaters just off of the bay front. I would hunt the small flocks trading between the rafts on the bay. You could call them and get a few to decoy to my small rig. I just would hunt for a few hours, and was partial to low tide when mud flats were exposed. I usually got a few, which was enough for me. I liked the experience of seeing lots of birds, and I also prefer to eat snow geese over canada geese-which I know is counter to most people. I like breast filets on the grill with a good cajun seasoning, like Paul Prudhommes meat magic. Seared on the outside and reddish pink inside, or sliced into medallions with some seasoned flour in a pan cooked in olive oil.
I also collected the cdc feathers for my fly tying, which I still do with the ducks that I shoot. I like the brilliant white ones that snow geese have, as I prefer collecting as many materials as I can from game I take , and the occasional road kill that is in good shape or a furbearer that I get from a friend who traps.
Anyway, I know that last part got a little off topic, but good luck on your search for snow geese. If you find them let us all know!
