That probably is right, but I think it was elk first. There is a heck of a lot of high fence hunting preserves here in the north east and they cater to elk and exotic hunters. We used to have a huge wild Chinese pheasant population here in PA. The biologists blamed it on DDT, clean farming, housing and who knows what when they disappeared. The pheasants disappeared so fast there is no way it could have been that. Right around that time there was an oriental bird flu hitting the chicken farms. There were hundreds of thousands (Millions?) of chickens slaughtered to try and stop it. The pheasant is from the orient and everybody and his brother was releasing them. Our Game Commission frowns on raising and releasing turkeys for that reason now. Our forests here are dieing because of foreign bugs and blights. Some introduced, some accidental. It is always playing with fire introducing something where it does not belong.
