Phylogeny for Gyps taxa based on mt cytB. The topology shown is the Bayesian inference majority rule tree. MP bootstrap nodal support values (greater than 50%) are below branches and the Bayesian posterior probability values are above. Numbers of individuals sampled per taxon are indicated in parentheses. Three additional outgroup species used in the analysis (S. calvus, T. tracheliotos, and T. occipitalis) are not shown.
