The phylogenetic and taxonomic status of galliformbirds is difficult to ascertain. This study reviews previous research on molecular techniques and morphological characteristics (e.g., plumage color) of Tragopan, Ithaginis, and Perdix to elucidate the polymorphism and taxonomic criteria of some galliform genera. Taxonomic criteria include genetic andmorphologic characteristics (e.g., body color). Plumage color is associated with sexual selection and environmental factors and, therefore, is an important criterion in bird taxonomy. The results of this study reveal the polymorphism of some galliform birds and the difficulty in ascertaining the taxonomic status of these birds.
