There are placing in Idaho that you can road hunt them, but other than that you'll probably need a good dog or need to get lucky.Being relatively new to chukar hunting my experience is limited, but after a few times walking right up to a covey that a dog was pointing without seeing them until I was 15-20 feet away I have come to realize that having a dog that knows chukar is almost a necessity.
The only other option is to take advantage of that early morning feeding behavior the article talks about. The first covey of the day is always doing exactly that.
I don't know how they count other upland birds, but I know they get a fairly accurate count with chukars when they fly over the areas that hold the little devils.I like how the state politicians pump up the bird #'s, deer, elk etc...#'s right before each season to ramp up the sales....what a joke!!
