I don't know where my previous post went, but here goes again.
I certainly think that the quail population is slowly coming back in this area. Mainly because more small rural farm operations have ceased, and the natural habitat is not being disturbed as much these days. Granted many people are buying these old farm places, but they're not utilizing them for a living. Only occasional hay mowing, and then only areas in which the new type machinery can operate. I noticed on my ranch where I've allowed the land to lay dormant, that there are coveys now that hadn't been in years.
