Stacy,
Its a beautiful shot, really like the kicked up snow dust! I vote willow; 1) female rock not likrly to show comb; 2)bill appears small but reaches back toward eye more like willow, seems to have unusual dark color in white plumage on top of bill. If you have picutres with this bird among willow pt. it would appear smaller with smaller features than the willow ptarmigan. All IMHO!
