Temporal range: Middle Miocene to present
Hieraaetus Kaup, 1844
Aquila is the genus of true eagles. It is often united with the buteos, sea eagles, and other more heavyset Accipitridae, but more recently it appears as if they are less distinct from the more slender accipitrine hawks than believed. Eagles are not a natural group, but denote essentially any bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrate prey.

Aquila belongs to an extremely close-knit group of "typical" eagles. These include genera such as Hieraaetus, Lophaetus, Ictinaetus, and the extinct Harpagornis, and all these appear to be paraphyletic with regards to the traditional Aquila. Especially some, if not all, species of Hieraaetus, separated primarily due to their smaller size, seem to belong here. The entire "typical eagle" group is in need of a thorough revision, thus this species list cannot be more than a tentative one at present.
Most problematic is certainly Hieraaetus, the hawk-eagles. The type species, the booted eagle, is known to be very close to some Aquila eagles. Other hawk-eagles might indeed be distinct enough to warrant generic separation, but the name Hieraaetus is not available for them, being a junior synonym of Aquila as the booted eagle is included herein.

It is not clear whether "Hieraaetus" edwardsi (Middle -? Late Miocene of SW Europe) belongs into Aquila or the hawk-eagles (if the latter are indeed distinct). Its initial name, "Aquila" minuta Milne-Edwards, 1871, is preoccupied by a junior synonym of the booted eagle, Aquila minuta Brehm, 1831.
Not placed in Aquila anymore are:
- "Aquila" gervaisii – now in Palaeohierax
- "Aquila" borrasi, "A." sodalis – now in Buteogallus. B. borrasi was long placed in Titanohierax.
- "Aquila" pliogryps – now in Spizaetus
- "Aquila" corroyi, "A." depredator, "A." hypogaea and "A." prisca – now in Aquilavus
- "Aquila" ferox, "A." lydekkeri – protostrigid owls, now in Minerva.
