I live in NE Ohio. As Bill Clark stated above, the quail here have taken a hit. When I was a kid, I grew up in farm country. We had a population of Bobwhites that numbered somewhere around a hundred. I could usually find a covey whenever I hunted for them. I had so much fun, me and 'Ole reckless, busting a covey, shooting a bird or two, then hunting up the singles. Next week, do it all over again. The winter of 76-77 then especially 77-78 decimated them all. Haven't seen a bird up this way since. I know the division has been trying to reintroduce the little fellas, but it just hasn't worked.
As far as other game, I can't really say. Seems like we'll have an especially bad weather season one year, but then a year or two later, the animals seem to bounce back quickly.
I've always been afraid more of the snow than cold. It seems to me, as long as the animals can find food, they have a much better chance of surviving.
My thoughts,
Jon
