Hieraaetus
The genus ''Hieraaetus'', sometimes known as small eagles or hawk-eagles, denotes a group of smallish eagles usually placed in the accipitrid subfamilies Buteoninae or Aquilinae. They are generally medium-sized birds of prey inhabiting Europe, Asia, Africa, New Guinea and Australia. However, a recently extinct species, the New Zealand Haast's eagle, was the largest eagle ever known, weighing up to , with a wingspan. Taxonomy and species The genus ''Hieraaetus'' was introduced in 1844 by the German naturalist Johann Jakob Kaup with the booted eagle as the type species. The name combines the Ancient Greek ''hierax'' meaning "hawk" with ''aetos'' meaning "eagle". Molecular genetic research has found ''Hieraaetus'' to be polyphyletic with '' Aquila''. '' Hieraaetus kienerii'' was found to be most distinct,proof a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Booted Eagle
The booted eagle (''Hieraaetus pennatus'', also classified as ''Aquila pennata'') is a medium-sized mostly migratory bird of prey with a wide distribution in the Palearctic and southern Asia, wintering in the tropics of Africa and Asia, with a small, disjunct breeding population in south-western Africa. Like all eagles, it belongs to the family ''Accipitridae''. Taxonomy The booted eagle was Species description, formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagle, falcons and relatives in the genus ''Falco (bird), Falco'' and coined the binomial nomenclature, binomial name ''Falco pennatus''. Gmelin based his description on "''Le Faucon Patu'' " or "''Falco pedibus pennatis'' " that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. Brisson had examined a specimen in the collection of Madame de Bandeville who wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wahlberg's Eagle
Wahlberg's eagle (''Hieraaetus wahlbergi'') is a bird of prey that is native to sub-Saharan Africa, where it is a seasonal migrant in the woodlands and savannas. It is named after the Swedish naturalist Johan August Wahlberg. Like all eagles, it belongs to the family Accipitridae. Description It is cross-shaped in flight with straight-edged wings and a square tail. Wahlberg's eagle is a medium-sized raptor, and the sexes are similar. It is about in length with a wingspan of and a body mass of for males and for females on average. The head has a small crest, and the legs are yellow. The plumage tone is variable but may be dark brown except for dark-streaked grey undersides to the flight feathers, and a barred grey undertail. Light and dark plumage phases occur. A pale variant may be much lighter brown with whitish, rather than grey undertail and flight feather undersides. The pale variant is much less common than the darker variant.

Little Eagle
The little eagle (''Hieraaetus morphnoides'') is a very small eagle endemic to Australia. Taxonomy John Gould Species description, described the little eagle in 1841. The distinctive pygmy eagle has long been considered a subspecies, but a 2009 genetic study shows it to be distinctive genetically and warrants species status. It is a near relative of both the Palearctic booted eagle and the massive but now Extinction, extinct Haast's eagle of New Zealand. Description The little eagle is a medium-sized bird of prey, measuring 45–55 cm (17–21.5 inches) in length and weighing 815 g (1.8 lb), roughly the size of a peregrine falcon.Barrett G, Silcocks A, Barry S, Cunningham R and Poulter R (2003). ''The New Atlas of Australian Birds'' (Royal Australasian Ornithologists Union, Hawthorn East, Victoria). It has fully feathered legs and a square-cut, barred tail. Wingspan is about 120 cm with males having longer wings in proportion to their bodies, but being nearly ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Eagle
The pygmy eagle or New Guinea hawk-eagle (''Hieraaetus weiskei'') is a bird of prey found in New Guinea. Its natural habitats are primarily subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is one of the smallest species of eagle. Taxonomy The pygmy eagle was described by German naturalist Anton Reichenow as ''Eutolmaetus weiskei'' in 1900. It was subsequently considered a subspecies of the little eagle or a distinct species. Gjershaug and colleagues analysed it genetically and found it distinct enough to warrant species status. The International Ornithologists' Union (IOC) subsequently recognised it as a distinct species. "Pygmy eagle" has been designated the official name by the IOC. Description Size The pygmy eagle is one of the world's smallest-known species of eagle and smallest living member of the Aquilinae subfamily, only rivaled by the Great Nicobar serpent eagle in diminutive size by all modern species referred to as ...

Halfway House: Southern Book Publishers. . is a medium-sized bird of prey in the family Accipitridae. It is native to African woodlands. Its name honours South African ornithologist Thomas Ayres. Description The adult male has blackish upper parts that are mottled with white and usually has a white forehead and supercilium. The upper-wing coverts are similar.

The underparts are white, with heavy dark brown spots and blotches on the breast and belly, becoming sparser on the thighs and vent. The legs are well-feathered and pure white. The under-wing coverts are brown and marked with white, and the underside of flight feathers is dark and heavily barred lacking any noticeable grey patch. The eyes are yellow to orange, the ...

Aquila (genus)
''Aquila'' is the genus of true eagles. The genus name is Latin for "eagle", possibly derived from ''aquilus'', "dark in colour". It is often united with the sea eagles, buteos, and other more heavyset Accipitridae, but more recently they appear to be less distinct from the slenderer accipitrine hawks than previously 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. Taxonomy and systematics The genus ''Aquila'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the golden eagle (''Aquila chrysaetos'') as the type species. ''Aquila'' belongs to a close-knit group of "typical" eagles including genera ''Hieraaetus'', '' Lophaetus'', '' Ictinaetus'' ''and Clanga.'' This group occurs as a clade within the larger group of "booted" eagles (tribe Aquilini or subfamily Aquilinae).Boyd, JohAccipitriformes, ''Taxonomy in Flux Checklist''. The pl ...

Haast's Eagle
Haast's eagle (''Hieraaetus moorei'') is an Extinction, extinct species of eagle that lived in the South Island of New Zealand, commonly accepted to be the of Māori mythology.Giant eagle (''Aquila moorei''), Haast's eagle, or Pouakai . Museum of New Zealand: Te Papa Tongarewa. Retrieved 27 October 2010. It is the largest eagle known to have existed, with an estimated weight of , compared to the next-largest and extant harpy eagle (''Harpia harpyja''), at up to . Its massive size is explained as an evolutionary response to the size of its prey—the flightless moa—the largest of which could weigh . Haast's eagle became extinct around 1445, following the Māori history#Settlement of New Zealand, arrival of the Māori, who hunted moa to extincti ...
