Bob,We bought our farm in southern ohio in 1972, there were 3 coveys of quail on the place. winters of 77'-78' wiped them out. In 2010 we planted 12 acres of warm season grasses, fall of 2011 i jumped the first covey since 1978. They are making a slow recovery but the landscape has changed. Gone are the small family farms with garden plots and small corn acreage replaced with housing,manicured lawns and kentucky 31 fescue . I baby the few birds we have with feeders when the ground is snow covered, their biggest enemy is hawks which are protected.
Part of the farm lays damp and attracts quite a few woodcock, i assume they are breeding there they can be seen and heard almost any spring evening.
