Bob white quail
I see coveys of quail at a few farms north of Portage. I have seen them consistantly for about 30 yrs. now. They are wild big fat bob whites. They would be mixed in with the grouse. Now rare to see a grouse, but the quail are still there.
About 10 years ago, I shot one. I think it was at Pine Island. My guess is that it was planted for dog training.
About 40 years ago we kicked up a big covey of them, which I assumed were wild. If memory serves me correctly, it was in the Brooklyn PHG.
Both times we were hunting pheasants.
