        The phylogenetic relationships among the six species of large eagles termed the 'Harpy Eagle group' remain poorly understood: Harpy Eagle (Harpia harpyja), Crested Eagle (Morphnus guianensis), Solitary Eagle (Harpyhaliaetus solitarius), Crowned Eagle (Harpyhaliaetus coronatus), New Guinea Harpy Eagle (Harpyopsis novaeguineae) and the Great Philippine Eagle (Pithecophaga jefferyi).  Currently, there are several alternative proposals in the literature about Harpy Eagle group phylogeny (Amadon, 1982; Amadon and Bull, 1988; Brown and Amadon, 1968; Dickenson et al., 1991); however, thorough genetic analyses are lacking.  I will try to determine if the six species placed in the Harpy Eagle group form a monophyletic group when additional Accipitridae species are included.  I will also address the sister relationships within the group and identify other Accipitridae species most closely related to the Harpy Eagle group.  This data would provide valuable information on the relative genetic distinctiveness among the members of the Harpy Eagle group and the relative ages and molecular uniqueness of the different taxa.  A phylogenetic context is also important for evaluating the history of changes in genotype, behavior, morphology, physiology and geographical distribution of harpy eagles.
