Common pheasant

The common pheasant (Phasianus colchicus), is a bird in the pheasant family (Phasianidae). It is native to Asia and has been widely introduced elsewhere as a game bird. In parts of its range, namely in places where none of its relatives occur such as in Europe (where it is naturalized), it is simply known as the "pheasant". Ring-necked pheasant is both the name used for the species as a whole in North America and also the collective name for a number of subspecies and their intergrades which have white neck rings.
