I will argue you on that... in the fall in the Arkansas delta you can't count the hawlks their are so many.
I have hunted South texas I did not see neer as many hawlks and I am not sure where the coons would hide.
I've seen the same thing in other states with healthy upland game-bird populations. I heard a ton of quail in central to north-central Kansas this spring. They probably had a good hatch as well. I also saw a fair number of pheasant in areas. I even saw prairie chickens. I don't think people realize what ground-nesting prey species such as quail, turkey, grouse, and pheasant face in the way of modern day predators in most areas of Arkansas today.
I guarantee you it's not as it was back when the Bobwhite was "king". Now it's truly hard to believe that quail hunting was even a real "thing" in Arkansas. I'm not even sure if people in Arkansas today even know that we once supported lots of quail, roughed grouse populations to an extent, prairie chickens were even native to the prairie (delta today), and people were even optimistic enough to attempt pheasant and grouse stockings. Things are not the same today. It wasn't pesticides in my area...
When I go out on our place (or many places in Arkansas) I commonly encounter these predators either in person or on game cams: (I'm not even sure how many different raptors/birds of prey species...but a lot - and in abundant numbers), other predatory birds (shrikes/blue jays/roadrunners, etc.), many types of snakes, opossums, absurd numbers of raccoons, more raccoons, grey foxes (rarely red fox), bobcats, coyotes everywhere, skunks, hordes of crows, tons of armadillos that seem to reproduce like mad, feral dogs, sometimes feral cats, bears, rarely mink, occasionally hogs, and that's just off the top of my head...
Many of these species weren't even "native" back in the 50's-70's, and I beg of you to tell me which ones were MORE numerous than today???
I don't see this this in the parts of Kansas I've hunted with healthy turkey and upland game bird populations. It's not comparable based simply on the types of habitat composition. I certainly don't think you can compare Arkansas as it was when we had thriving ground-nesting bird populations to what is commonly encountered in Arkansas today.
Good luck AGFC, just keep trying the same things over and over again. Maybe it'll work this time... Too bad no quail hunters are left hunting Arkansas to speak of, so good luck getting support...that's what inaction gets you...(hint, hint).
