Generally......Fields to feed. Open water to rest.
Most Mississippi flyway geese are currently north of central Illinois. With all the retention/detention ponds up north and the lack of snow/very cold weather, they do not migrate like in years past. It takes a serious cold spell and more importantly a long lasting snow cover to push them south.
Check the Ducks Unlimited website. Some hunters post migration updates on there. Not sure if they do so for geese as much as ducks.
Shot one short of a five man limit several weeks ago. One was banded.
