    Abstract:
    A study of the phyletic relationships among five species of tragopans and an outgroup, the Blood Pheasant (Ithaginis cruentus), was conducted from 1987 to 1991. Biochemical, behavioral, and external morphologic characteristics were compared. A cladistic approach was used to compare the behavioral, biochemical, and external morphologic data collectively, as different...
