edit: sorry about the bad posting format!!
Basically 8 hunting seasons quail were tracked and tabulated with hunting success at a commercial (?) hunting preserve. In 8 pages including graphs and tables they summarize when quail are active, % successful points, % birds walked past, pointed & ran vs flushed vs held etc. They conclude with a list of hunting tips based on the study.
