We used to have birds galore . no more . Back in the mid 60's I could walk up 10 covies and not lose sight of the house .Fire ant were a real problem so myrex was sprayed to reduce the huge mounds everywhere in north ms. There was a drift problem while spraying from the plane so the idea to mix with crushed corn cobs was cheap and settled faster to the ground . Things went south for the birds as the cobs were not totally without corn bits after grinding . Within 5 years the birds were in great decline . Small farms were less in numbers (lost habitat) and release of coyotes all played a part in the demise of bob white quail . I was 16 before I ever deer hunted (actually were very few in my area then )as quail, rabbit, and squirrel was the rule of that day . I do not know anybody that owns a bird dog .
