Related Species

Prior to the mid-20th century, the dark morph was classified as a separate species (Morphnus taeniatus Gurney 1879). It was not until 1949 that the two morphs were recognized as a single species (Hellmayr and Conover 1949).

Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, indicates that the closest living relative of the Crested Eagle is the Harpy Eagle (Harpia harpyja) and that these two species are at the base of the aquiline eagle radiation (Helbig et al. 2005, Lerner and Mindell 2005).
