As long as we have an abundance of cooper hawks and sharpshinned hawks, you will not be able to bring back quail. You have to address the predation problems, or it will be like the pheasant project. If the quail project fails they can always blame it on westnile, funny thing is even though west nile is proven to be hard on hawks, owls ,crows and bluejays, these predators seem to be able to do well number wise, with west nile, however everything they prey on has dropped in numbers. Just a few facts. Quail numbers are way down , in the south even with good habitat. To increase a game population, you must increase reproduction, and decrease mortality, and if your main mortality factor is predation, you must lower predator numbers. This is the way science works, the results of the pheasant restoration areas show how nature works when you provide the great habitat, but do not address the predation problem, which in the case of pheasants, was raptors causing the most mortality.
