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. ...

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the '' Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, ... [...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 ...

Birds Described In 1900
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Eagles
Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 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. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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] |
Brown Cuckoo-dove
The brown cuckoo-dove (''Macropygia phasianella'') is a dove in the genus ''Macropygia'' found in Australia from Weipa and Aurukun in the north to Bega in the south, and most inland at Atherton and Toowoomba. It is sometimes called the "brown pigeon" or "pheasant pigeon", but both terms are best avoided, as they can lead to confusion with the brown doves and the true pheasant pigeon. It was one of three new species defined when the slender-billed cuckoo-dove was split in 2016. Taxonomy The brown cuckoo-dove was formally described in 1821 by the Dutch zoologist Coenraad Jacob Temminck from a specimen collected near Port Jackson in New South Wales, Australia. He coined the binomial name ''Columba phasianella''. The specific name is a diminutive of the Latin ''phasianus'', meaning "pheasant". The brown cuckoo-dove is now placed in the genus ''Macropygia'', which was introduced by the English naturalist William John Swainson in 1837. Three subspecies are recognised: * ''M. ...

Moluccas
The Maluku Islands (; Indonesian: ''Kepulauan Maluku'') or the Moluccas () are an archipelago in the east of Indonesia. Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located east of Sulawesi, west of New Guinea, and north and east of Timor. Lying within Wallacea (mostly east of the biogeographical Weber Line), the Maluku Islands have been considered as a geographical and cultural intersection of Asia and Oceania. The islands were known as the Spice Islands because of the nutmeg, mace and cloves that were exclusively found there, the presence of which sparked colonial interest from Europe in the sixteenth century. The Maluku Islands formed a single province from Indonesian independence until 1999, when it was split into two provinces. A new province, North Maluku, incorporates the area between Morotai and Sula, with the arc of islands from Buru and Seram to Wetar remaining within the existing Maluku Pr ...

Buru
Buru (formerly spelled Boeroe, Boro, or Bouru) is the third largest island within the Maluku Islands of Indonesia. It lies between the Banda Sea to the south and Seram Sea to the north, west of Ambon and Seram islands. The island belongs to Maluku province and includes the Buru and South Buru regencies. Their administrative centers, Namlea and Namrole, respectively, have ports and are the largest towns of the island, served by Namlea Airport and Namrole Airport. About a third of the population is indigenous, mostly Buru, but also Lisela, Ambelau and Kayeli people. The rest of population are immigrants from Java and nearby Maluku Islands. Religious affiliation is evenly split between Christianity and Sunni Islam, with some remnants of traditional beliefs. While local languages and dialects are spoken within individual communities, the national Indonesian language is used among the communities and by the administration. Most of the island is covered with forests rich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird's Head Peninsula
The Bird's Head Peninsula ( Indonesian: ''Kepala Burung'', nl, Vogelkop) or Doberai Peninsula (''Semenanjung Doberai''), is a large peninsula that makes up the northwest portion of the island of New Guinea, comprising the Indonesian provinces of Southwest Papua and West Papua. The peninsula just to the south is called the Bomberai Peninsula, while the peninsula at the opposite end of the island (in Papua New Guinea) is called the Bird's Tail Peninsula. Location and geography The Bird's Head Peninsula is at the northwestern end of the island of New Guinea. It is bounded by Cenderawasih Bay to the east, Bintuni Bay to the south, and the Dampier Strait to the west. Across the strait is Waigeo, an island in the Raja Ampat archipelago. Batanta island lies just off the peninsula’s northwest tip. Another peninsula, Bomberai Peninsula, lies to the south, across Bintuni Bay. The peninsula is around 200 by 300 kilometers, and is bio-geographically diverse, containing coastal plai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or ...

Great Nicobar Serpent Eagle
The Great Nicobar serpent eagle (''Spilornis klossi''), also known as the South Nicobar serpent eagle, is a species of bird of prey in the family Accipitridae. It is probably the smallest known eagle, with a weight of about , a wingspan of and a body length of about .Clark, W.S., G. M. Kirwan, and D. A. Christie (2020). ''Nicobar Serpent-Eagle (Spilornis klossi)'', version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. It is endemic to forest on the Indian island of Great Nicobar. It is threatened by habitat loss. All major authorities now treat the Great Nicobar serpent eagle as a species, but in the past it was sometimes considered a subspecies of ''S. minimus''. Today ''S. minimus'' is either considered a subspecies of the crested serpent eagle or a monotypic species from the central Nicobar Islands, the Central Nicobar serpent eagle The crested serpent eagle (''Spilo ...
