Hieraeetus
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 medium-sized birds of prey inhabiting Europe, Asia, Africa, New Guinea and Australia. 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, and has been assigned to a separate genus, '' Lophotriorchis''. [...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 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'' and coined the 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 was also known as Marie Anne Catherine Bigot de Graveron (1709-1787 ...

Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like '' Pterosauria'' and ''Machairodus''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated this work as a youthful indiscretion, and on the publication of Darwin's ''Origin of Species' ...

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.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301-320. The African hawk-eagle breeds in tropical Sub-Saharan Africa. It is a bird of assorted woodland, including both savanna and hilly areas but the 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.

Giant Haasts Eagle Attacking New Zealand Moa
In folklore, giants (from Ancient Greek: '' gigas'', cognate giga-) are beings of human-like appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word ''giant'' is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the ''Gigantes'' ( grc-gre, Γίγαντες) of Greek mythology. Fairy tales such as '' Jack the Giant Killer'' have formed the modern perception of giants as dimwitted ogres, sometimes said to eat humans, while other giants tend to eat the livestock. The antagonist in ''Jack and the Beanstalk'' is often described as a giant. In some more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly. Literary and cultural analysis Giants appear in the folklore of cultures worldwide as they represent a relatively simple concept. Representing the human body enlarged to the point of being monstrous, giants evoke terror and remind humans o ... [...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.

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 was 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 eagles.

Little Eagle
The little eagle (''Hieraaetus morphnoides'') is a very small eagle native to Australia, measuring 45–55 cm (17–21.5 inches) in length and weighing 815 g (1.8 lb), roughly the size of a peregrine falcon. It tends to inhabit open woodland, grassland and arid regions, shunning dense forest. It is a near relative of both the Palearctic booted eagle and the massive but now extinct Haast's eagle of New Zealand. 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. Description Barrett, et al. (2003), describes the little eagle as a medium-sized bird of prey, between 45 and 55 cm in length. The little eagle is small and stocky with a broad head. It has fully feathered legs and a square-cut, barred tail. Wingspan is about 120 cm with males having longer wings in proportion t ...
