New soft deep snow will inhibit their movement quite a bit. Once the snow firms up so they can get around without falling to deep, they will go further. Then is a good time to go looking around spring seeps where the snow doesn't stay and they can forage around. Just like these birds and the story of the pics:

I got these from game-cam. I had spotted some birds while traveling to take cam out of woods (decided not to bring it home then lol), and backtracked to see where they had been. Found they had been hitting a couple weeps pretty hard with the snow on the ground, so I put cam near one place un-traveled by people (other place was popular with snow-shoers and skiers). First week they didn't go back due to new soft snow, but after a couple breezy days followed by a couple melting days, then colder, the snow pack firmed up nicley and got them moving again. Saturday I ended up spooking them out of traveled area (whoops) and they hadn't been been by cam, but I went back sunday (and spooked them again dern it), and they had used up entire roll of film. Have to wait and see if I can get a gobbler or two ( I did see one J dropping in area)
