On the subject of pen raised pheasants, we have two sides to that story. We have on one hand, the tame non alert non wary ( 70 or more generations of easy going pen life) pen raised pheasants. And on the other hand we have F1 (only a few generations removed from the wild state) wilder predator alert and predator wary pen raised pheasants.
Remember all of our wild pheasants originated at one time from pen raised birds but after 60 or 70 generation of living in the real wild world all of the dumb ones are long gone and only wary and alert pheasants live long enough to reproduce in the wild.
The link below gives a good history of the Texas panhandle pheasants, notice the gene pool is made up of wilder strains (predator wary and predator alert) of pen raised pheasant like the Manchurian Ringneck pheasants the White-Winged pheasant the wilder regular ringnecks:
http://amarillo.com/stories/120201/whe_legionsofspo.shtmlNow days commercially available pen raised pheasant can easily be over 50 generations of pen life. The pen raised pheasants released 100 years ago were probably closed to f1 wilder birds.
We need to get some new authentic wilder pheasants to give to the commercial breeders to use as brood stock. Look at this link at authentic wild pheasants overseas. Notice the light iris.
