Taxonomic note: Edwards's Pheasant (Lophura edwardsi) was previously split as (L. edwardsi) and Vietnamese Pheasant (L. hatinhensis) following Sibley and Monroe (1990, 1993). Imperial Pheasant Lophura imperialis (Sibley and Monroe 1990, 1993) is considered a hybrid between Silver Pheasant (Lophura nycthemera) and Edwards's Pheasant (L. edwardsi) following Rasmussen (1998).
The Edwards's Pheasant and Vietnamese Pheasant are probably just one, the females are undistinguished. The male on Vietnamese has 4 white feathers on its tail so it is suggested that they are one!
Need more study on DNA.
