Old enought to draw a crazy check for chasin a bird around that seems to be non existant I don't know the answer to the decline, but I do know habitat is being created everyday in my kneck of the woods. I'm not gonna rely on the FW, GHA, or whatnot to make birds for me to hunt. If you do that, you may never see a bird on public ground. I don't hunt public, I hunt 100 percent private. Ill leave it to the poor landowners around here who need a lil extra to have their logs hauled away. Some may say, "Well that aint helping out none." No on public its not. For what I hunt, it is. We know our biggest factor on WMAs and whatnot, but on private, I believe its predators. Avian predators more than anything, althought bobcats and yotes are on the rise.
