- "Aquila minuta" redirects here. If based on Brehm (1831), it refers to this bird. The fossil bird described under the same name by Milne-Edwards (1871) is preliminarily known as "Hieraaetus" edwardsi but might belong in Aquila.
- The Booted Eagle (Aquila pennata) (formerly Hieraaetus pennatus) is a medium-sized bird of prey. It is about 48 centimetres (19 in) in length and has a wingspan of 120 centimetres (47 in). Like all eagles, it belongs to the family Accipitridae.
The Booted is a small eagle, comparable to the Common Buzzard in size though more eagle-like in shape. Males grow to about 700 grams (1.5 lbs) in weight, with females close to 1 kilogram (over 2 lb). There are two relatively distinct plumage forms. Pale birds are mainly light grey with a darker head and flight feathers. The other form has mid-brown plumage with dark grey flight feathers.
The call is a shrill kli-kli-kli.
Recent genetic research resulted in the reclassification of this species to the genus Aquila from Hieraaetus. As it is the type species of Hieraaetus, should any of the hawk-eagles be retained in a distinct genus a new name for that group would be necessary.
