Light morph from below Showing the white marking on the wings termed as "landing lights" The booted eagle is a small eagle, comparable to the common buzzard in size though more eagle-like in shape. Males grow to about 510–770 g (1.12–1.70 lb) in weight , with females about 840–1,025 g (1.852–2.260 lb) with a length of 40 cm and a ...
Wingspan can vary from 39 cm (15 in) in the little sparrowhawk to more than 300 cm (120 in) in the cinereous and Himalayan vultures (Gyps himalayensis). In these extreme species, wing chord length can range from 113 to 890 mm (4.4 to 35.0 in) and culmen length from 11 to 88 mm (0.43 to 3.46 in).
The wings are held flat or slightly upraised at the tip in flight and the white-tailed eagle is well known to soar extensively. This species can be surprisingly maneuverable on the wing, usually during aerial displays or dogfights with other birds. These eagles may also maneuver by half-closing both wings or fully closing one wing. [6] [12] [55]

The wingspan is around 2.2 times greater than the bird's total length. [4] They tend to fly with rather loose but deep and powerful beats. Wedge-tailed eagles spend much time sailing along, looking quite stable and controlled even in strong winds. The species glides and soars on upswept wings with long splayed primaries.
The fish eagles, booted eagles, and harpy eagles have traditionally been placed in the subfamily Buteoninae together with the buzzard-hawks (buteonine hawks) and harriers. Some authors may treat these groups as tribes of the Buteoninae; Lerner & Mindell [ 26 ] proposed separating the eagle groups into their own subfamilies of Accipitridae .
Adults are 59 to 70 cm (23 to 28 in) long with a 162 to 195 cm (5 ft 4 in to 6 ft 5 in) wingspan and weigh 1.2–2.3 kg (2.6–5.1 lb), an average weight for the species is about 1.7 kg (3.7 lb). [ 12 ] [ 13 ] [ 14 ] They can be recognised in the field by their predominantly white underside, the upper parts being greyish brown.
Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3] A bird strike was recorded at this height in 1973 ...
