sentences:  Genetically, the “spotted eagles” ("A. pomarina, hasata & clanga"), have been discovered to be more closely related to the long-crested eagle ("Lophaetus occipitalis") and the black eagle ("Ictinaetus malayensis"), and many generic reassignments have been advocated.The genus "Hieraaetus", including the booted eagle ("H. pennatus"), little eagle ("H. morphnoides") and Ayres's hawk-eagle ("H. ayresii"), consists of much smaller species, that are in fact smallest birds called eagles outside of the unrelated "Spilornis" serpent-eagle genus.This genus has recently been eliminated by many authorities and is now occasionally also included in "Aquila", although not all ornithological unions have followed this suit in this re-classification.
