The Harpiinae is a bird of prey subfamily which consists of large broad-winged species native to tropical forests. There are 4 genera in the subfamily, all monotypic. [3] [4]The cladogram of the Harpiinae shown below is based on a molecular phylogenetic study of the Accipitridae by Therese Catanach and collaborators that was published in 2024.
Accipitriformes, currently with 262 species and 75 genera in 4 extant families and possibly 1 extinct family, is the largest diurnal raptor order. DNA sequence analyses suggest that divergences within Accipitriformes began around the Eocene/Oligocene boundary about 34 mya, with the split of the group including genera Elanus and Gampsonyx from ...

Here is an image of a Harpy Eagle's talon next to those of other species (left to right: Harpy Eagle, Golden Eagle, Bald Eagle, Great Horned Owl, Red-tailed Hawk and Peregrine Falcon). Compare this with 64.75 mm for the Harpy Eagle and 55 m for the Golden Eagle (can reach c60 mm) at haribon.org (see cache if that doesn't open).
