Don't have an answer to the original question, but they are definitely bigger than our normal quail and about 100 times harder to hunt. I used to hunt them quite a bit while in school in Eugene, and there were quite a few in the hills around there. They seem to be pretty localized, but if you found the right spot there were tons of them. The damn things run a lot, fly quickly, and never seem to fly very high. They mostly darted in and out of the reprod and laughed at my while I blasted limbs trying to hit the damn things.
