There are 05 endemic species of Vietnam includes Germain’s Peacock Pheasant
(Polyplectron germaini), Lophura nycthemera annamensis, Black-hooded laughingthrush (Garrulax millet), Garrulax annamensis, Jabouileia danjoui and other interested endemic species in the world. The endemic ones are rare and precious species and most of them are threatened at different level. (Dang Huy Huynh et.al, 1998)
