When you start seeing pics like these it's no longer a question of if the birds will move it's just a question of how far. This particular shot came from the Cypress Hills in the southwest corner of the province with a solid 4 to 10 inches spread from the Montana line up to Saskatoon and its still falling.
Bow hunting Northeast of Bismarck last night you could hear quite a few different groups of specks coming over. It will definitely be interesting to see if any new birds are moving in.
