Areas that are presently being managed for quail have large numbers of birds and they are NOT (can't when it comes to hawks) doing predator management. You all are barking up the wrong tree when you keep focusing on predators as a part of the problem. It is all about habitat!!! Also many of those hawks you are seeing are red-tailed hawks, northern harriers, and red-shouldered hawks. These species of hawks are not commonly predators of birds. Yes predators and some of those being smaller hawks, which are not commonly seen, do take birds but that is a part of nature. Predators only have the CHANCE (but may not) to become an issue when habitat has been degraded/reduced/changed. Blaming the predators becomes too easy of a scapegoat rather that trying to deal with the real and harder issue of habitat loss. As I pointed out at the beginning we know in this day and time that we can have plenty of quail with the proper habitat WITHOUT predator control!
