The nominate (Caucasian) subspecies of Common Pheasant has NO WHITE NECK COLLAR. The one above has a slight patch of collar on the left, indicating it is not pure-bred. Mongolian and Chinese subspecies have white neck collars, the former with a dark rump and the latter with a light rump. The common European/American Ring-necked Pheasant, which generally has a three-quarter, white collar, is a stable hybrid population of various subspecies of Common Pheasant (and possibly also the Japanese Green Pheasant) imported/bred for hunting.
