I think they do. Even their toes are covered in feathers by Thanksgiving. They get very jumpy though. Tough to get a sharptail in shotgun range once their is snow on the ground. As far as color I think it's the same. I have never noticed. I don't do that much shotgun hunting. Even the squirrels I do with a 50 cal Hawken. I think it's been three years or more since I shot a duck.
