I was out Sat. morning just west of Oak Hammock marsh just north of Winnipeg. I have never seen so many birds this early in the season before. I saw 3 seperate flocks, each of at least 5000 birds. The skies were just black with the big Canadas. Only took 3 (5 bird limit) and just spent the rest of the time just watching (might sound stupid but I've losts of time to fill the freezer limit and was having some friends over for dinner Sat. night and just wanted enough for dinner). All three were greater Canada's and very big birds. Looks like it's going to be a great season. You guys down south get ready for some great hunting.
