While it's certainly possible to find either species in the same area, hunting mature and mule deer bucks is generally a different process. Unless in the rut, I have had my best success hunting Western whitetail bucks either early or later in the day either near food bearing farmland areas, or positioning in a hide in proximity to the green river bottoms, catching them in transit…They frequent these areas. The further the distance and greater the visual expanse, the better. Given you have already had a successful whitetail doe hunt, a buck will usually be in proximity, but the mature whitetail will be quite savvy and require more careful planning compared to the younger bucks and does. Stalking a mature whitetail, while possible, is far more difficult then a muley. My greatest success with mule deer has been lots of glassing in hopes of locating a buck standing or bedded on the mountain/hillsides looking for either the shot, or a stalk to get within range. This type of hunting can be productive throughout the day. If I have a tag for either, or a tag for each, I will often hunt whitetails early and late in the day, and mule deer in the balance of the day. I personally love to hunt the Western whitetail overlooking a valley/river bottom. It was made for the long range hunter, and quite different from hunting whitetails in other parts of the country!
