You are right that they will be getting hungry and that is greatly to your advantage as they need to eat more just to stay alive. Even a sparrow will eat up to five times more under these conditions as it has to to keep from freezing solid.
I have been out to many times to count in the blizzard like conditions. I could usually find tracks along the smaller woods sheltered tributes that feed the larger drainages.
Brushy fence lines, hedge rows, and multiflower rose or briar patches can also be good.
Hope this helps some
