Booted Eagles
Booted eagles are eagles that have fully feathered tarsi. That is, their legs are covered with feathers down to the feet. Most other accipitrids have bare lower legs, scaled rather than feathered. They may be treated as an informal group, as distinct from "fish eagles" (or "sea eagles"), "snake eagles", and "giant forest eagles". They may also be treated as a formal taxon, either as a tribe (Aquililae) or subfamily ( Aquilinae). The booted eagles, sea eagles, harpy eagles and buteonine hawks are heavily built birds that have traditionally been classified together in the large subfamily Buteoninae. In 2005, Heather Lerner and David Mindell proposed separating the eagles into their own subfamilies Aquilinae, Haliaeetinae, and Harpiinae, leaving only the buteo–buteogallus clade in a more restricted Buteoninae. Included in the booted eagles are the genera ''Aquila'', ''Hieraaetus'' and ''Clanga''; all species described as "hawk eagles" including the genera '' Spizaetus'' and ...

Eagle
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family of the Accipitridae. Eagles belong to several groups of Genus, genera, some of which are closely related. True eagles comprise the genus ''Aquila (bird), Aquila''. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—two in North America, nine in Central and South America, and three in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Etymology The word "eagle" is borrowed into English from and , both derived ultimately from ("eagle"). It is cognate with terms such as , and . It is broadly synonymous with the less common English term "erne" or "earn", deriving from , from , in which it acts as the usual word for the bird. The Old English term is turn derived from and is cognate with other synonymous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Eagle
The golden eagle (''Aquila chrysaetos'') is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known bird of prey, birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as . They build large bird nest, nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Fem ...

Clanga (genus)
''Clanga'' is a genus which contains the spotted eagles. The genus name is from Ancient Greek ''klangos'', "eagle". Taxonomy The genus ''Clanga'' was described in 1854 by the Polish naturalist Adam Ferdynand Adamowicz (1802-1881). The type species is ''Falco maculatus'' J. F. Gmelin, 1788, a synonym of ''Aquila clanga'' (the greater spotted eagle) that was described in 1811 by Peter Simon Pallas. '' Falco maculatus'' J. F. Gmelin is preoccupied by ''Falco maculatus'' Tunstall 1771 but under the rules of the International Code of Zoological Nomenclature ''Falco maculatus'' is still considered to be the type species. The genus name is from Ancient Greek ''klangos'' meaning "eagle". A molecular phylogenetic study of the Accipitridae published in 2024 found that the genus ''Clanga'' was sister A sister is a woman or a girl who shares parents or a parent with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Spotted Eagle
The greater spotted eagle (''Clanga clanga''), also called the spotted eagle, is a large migratory bird of prey in the family Accipitridae. It is a member of the subfamily Aquilinae, commonly known as "booted eagles".Helbig, A. J., Kocum, A., Seibold, I., & Braun, M. J. (2005). ''A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level''. Molecular phylogenetics and evolution, 35(1), 147-164. It was once classified as a member of the genus ''Aquila (bird), Aquila'', but has been reclassified to the distinct genus ''Clanga (bird), Clanga'', along with the two other species of spotted eagle.Helbig, A. J., Seibold, I., Kocum, A., Liebers, D., Irwin, J., Bergmanis, U., Meyburg, B.-U., Scheller, W., Stubbe, M. & Bensch, S. (2005).

Indian Spotted Eagle
The Indian spotted eagle (''Clanga hastata'') is a large bird of prey native to South Asia. Like all typical eagles, it belongs to the family Accipitridae. The typical eagles are often united with the buteos, sea eagles and other more heavy-set Accipitridae, but more recently it appears as if they are less distinct from the more slender accipitrinae, accipitrine hawks. Description The Indian spotted eagle is about 60 cm in length and has a wingspan of 150 cm. It is broad-headed, with the widest mouth of all spotted eagles.Parry, S.J., Clark, W.S., Prakash, V. (2002) On the taxonomic status of the Indian Spotted Eagle ''Aquila hastata''. Ibis Volume 144 Issue 4: 665 - 675 This species is a lighter overall compared to its relatives, with a darker iris (eye), iris that makes the eyes appear darker than the plumage (rather than the other way around as in the two northern spotted eagle species). Adults can be told apart from the greater spotted eagle by its lighter colour, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Spotted Eagle
The lesser spotted eagle (''Clanga pomarina'') is a large Eastern European bird of prey. Like all typical eagles, it belongs to the family Accipitridae. The typical eagles are often united with the buteos, sea eagles, and other more heavy-set Accipitridae, but more recently it appears as if they are less distinct from the more slender accipitrine hawks than believed. Description This is a medium-sized eagle, about in length and with a wingspan of . Its head and wing coverts are pale brown and contrast with the generally dark plumage. The head and bill are small for an eagle. Usually, a white patch occurs on the upper wings, and even adults retain a clearly marked white "V" on the rump; the wing markings are absent and the white "V" is not well-defined in the greater spotted eagle. The juvenile has less contrast in the wings, but the remiges bear prominent white spots. It differs from greater spotted eagle juveniles by a lack of wing covert spotting and the presence of a cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe Eagle
The steppe eagle (''Aquila nipalensis'') is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. The steppe eagle's well-feathered legs illustrate it to be a member of the subfamily Aquilinae, also known as the "booted eagles".Helbig, A. J., Kocum, A., Seibold, I., & Braun, M. J. (2005). ''A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level''. Molecular phylogenetics and evolution, 35(1), 147–164. This species was once considered to be closely related to the bird migration, sedentary tawny eagle (''Aquila rapax'') and the two forms have previously been treated as Biological specificity, conspecific. They were split based on pronounced differences in morphology and anatomy; two molecular studies, each based on a very small number of genes, indicate that the species are distinct but disagree over how closely related they are. The steppe eagle is in many ways a peculiar species of eagle. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tawny Eagle
The tawny eagle (''Aquila rapax'') is a large bird of prey. Like all eagles, it belongs to the family ''Accipitridae''. Its heavily feathered legs mark it as a member of the subfamily Aquilinae, also known as booted eagles.Helbig, A. J., Kocum, A., Seibold, I., & Braun, M. J. (2005). ''A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level''. Molecular phylogenetics and evolution, 35(1), 147-164. Tawny eagles have an extensive but discontinuous breeding range that constitutes much of the African continent as well as the Indian subcontinent, with rare residency in the southern Middle East. Throughout its range, it favours open dry habitats such as semideserts, deserts steppes, or savanna plains. Despite its preference for arid areas, the species seldom occurs in areas where trees are entirely absent.Hustler, K., & Howells, W. W. (1989).

Spanish Imperial Eagle
The Spanish imperial eagle (''Aquila adalberti''), also known as the Iberian imperial eagle, the Spanish eagle or Adalbert's eagle, is a species of eagle native to the Iberian Peninsula. The binomial commemorates Prince Adalbert of Bavaria. Due to its distinct "epaulettes", old literature often referred to this species as the white-shouldered eagle. Formerly, the Iberian imperial eagle was considered to be a subspecies of the eastern imperial eagle, but is now widely recognised as a separate species due to differences in morphology, ecology, and molecular characteristics. Description This is a large raptor and quite large eagle, broadly similar in size to its cousin, the eastern imperial eagle, which is found in a considerably different distributional range. Compared to sympatric largish booted eagles, it is somewhat smaller than the golden eagle and somewhat larger than the Bonelli's eagle. Spanish imperial eagle can weigh from .

Eastern Imperial Eagle
The eastern imperial eagle (''Aquila heliaca'') is a large bird of prey that breeds in southeastern Europe and extensively through West and Central Asia. Most populations are migratory and winter in northeastern Africa, the Middle East and South and East Asia. Like all eagles, the eastern imperial eagle is a member of the family Accipitridae. Furthermore, its feathered legs mark it as a member of the subfamily Aquilinae. It is a large, dark-colored eagle, with a resemblance to other members of the genus '' Aquila'', but it is usually the darkest species in its range.Forsman, D. (1999). ''The raptors of Europe and the Middle East: a handbook of field identification''. London: T & AD Poyser. It is an opportunistic predator that mostly selects smallish mammals as prey but also a fairly large proportion of birds, reptile and other prey types, including carrion. Compared to other ''Aquila'' eagles, it has a strong preference for the interface of tall woods with plains and other open, r ...

African Hawk-eagle
The African hawk-eagle (''Aquila spilogaster'') is a large bird of prey. Like all eagles, it belongs to the family ''Accipitridae''. This species' feathered legs mark it as a member of the Aquilinae subfamily. The African hawk-eagle breeds in tropical Sub-Saharan Africa. It is a bird of assorted woodland, including both savanna and hilly areas, but they tend to occur in woodland that is typically dry. The species tends to be rare in areas where their preferred habitat type is absent. This species builds a stick nest of around across in a large tree. The clutch is generally one or two eggs. The African hawk-eagle is powerfully built and hunts small to medium-sized mammals and birds predominantly, occasionally taking reptiles and other prey as well.Steyn, P. (1983). ''Birds of prey of southern Africa: Their identification and life histories''. Croom Helm, Beckenham (UK). 1983. The call is a shrill ''kluu-kluu-kluu''.

Bonelli's Eagle
Bonelli's eagle (''Aquila fasciata'') is a large bird of prey. The common name of the bird commemorates the Italian ornithologist and collector Franco Andrea Bonelli. Bonelli is credited with gathering the type specimen, most likely from an exploration of Sardinia.Aimassi, G. (2015). ''The original description of Bonelli's Eagle Aquila fasciata Vieillot (Aves: Accipitridae)''. Zoological Bibliography, 4(1), 1-15. Some antiquated texts also refer to this species as the crestless hawk-eagle. Like all eagles, Bonelli's eagle belongs to the family Accipitridae. Its feathered legs marked it as member of the Aquilinae or booted eagle subfamily. This species breeds from Southern Europe, Africa on the montane perimeter of the Sahara Desert, and across the Indian Subcontinent to Indonesia. In Eurasia, this species may be found as far west as Portugal and as far east as southeastern China and Thailand. It is usually a resident breeder. Bonelli's eagle is often found in hilly or mountainou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
