Quail depend on weather conditions more than most other species. Last year they had declined from previous years to below the 15 year average. However, from 2014-2017 they were at record numbers not seen since the 1970’s. Loss of habitat through human growth does play in to that, but from experience hunting South Texas in 2017 I couldn’t go more than 200 yards without flushing a new covey during dove season.
