I find they are somewhere between a quail and chukar. To be fair, I shoot most when I am chukar hunting. Seem to get them in less steep areas (ridgetops) and also sometimes in areas where there is some brush. I think like chukar they like cheet grass. Unlike chukar, rocks and huns don't seem to go together.
Most prolific spot I have found is on a pretty substantial hillside where I burn went through years ago and burned up the sage leaving grass to grow in after.
