In WA we have pheasant, quail, chukar, hungarian partridge and grouse. On the westside we have grouse (ruffed, blue and spruce) and quail (california, mountain and bobwhite). I have never seen mountain quail or bobwhite, and rarely find quail while hunting westside. If you really want to hunt chukar, it can be done with a lab. Once you find them (I won't tell you where) you can hunt them without covering too many miles. They hold better late season with the colder weather. They also hold in little to no cover, trust your dog's nose and be ready for a steep learning curve. Quail are all over E WA, usually close to water. They fly much faster and more erratic than pen raised pheasant. We do have rattlesnakes in E WA, they're not terribly common, but be aware during early season.
Yakima indian reservation has good quail hunting, but requires a separate license. If you decide to hunt there, be aware car break ins/theft is a concern. Pheasant hunting on the rez hasn't been great the last few years, but they are around
