Harpaginae
Harpaginae is a subfamily of the bird of prey family Accipitridae. The species are found in Central and South America. The subfamily was introduced (as Harpageae) by the French naturalist Charles Lucien Bonaparte in 1854 with '' Harpagus'' Vigors, 1824 as the type genus. The genera ''Microspizias'' and ''Harpagus'' have in the past been placed in a subfamily Milvinae but molecular phylogenetic studies have shown that such a grouping is polyphyletic for Buteoninae The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species. They have large, powerful, hooked beaks for tearing flesh from their prey, strong legs, and powerful talons. They also have extremely keen .... Species The subfamily contains four species in two genera: * '' Microspizias'' ** Tiny hawk (''Microspizias superciliosus'') ** Semicollared hawk (''Microspizias collaris'') * '' Harpagus'' ** Double-toothed kite (''Harpagus bidentatus'') ** Rufous-thighed kite ( ...

Accipitridae
The Accipitridae () is one of the four families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents (except Antarctica) and a number of oceanic island groups. Some species are migratory. The family contains 256 species which are divided into 12 subfamilies and 75 genera. Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family ( Pandionidae), as is the secretary bird ( Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data indicate the accipitrids analysed are indeed a distinct monophyletic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microspizias
''Microspizias'' is a genus of bird of prey in the family Accipitridae. It contains the following species: * Tiny hawk (''Microspizias superciliosus'') * Semicollared hawk (''Microspizias collaris'') Both species were formerly classified in the genus ''Accipiter'', but a 2021 report, based on earlier research which found them to be strongly phylogenetically distinct, described a new genus (''Microspizias'') for them. This was also followed by the International Ornithological Congress and the American Ornithological Society. Etymology ''Microspizias'' derives from the Greek word ''micros'' ("small") and ''spizias'' ("hawk"), literally translating to "small hawk". Taxonomy Phylogenetic evidence indicates that ''Microspizias'' is the sister genus to the lizard buzzard (''Kaupifalco monogrammicus'') of Africa and falls outside the Accipitrinae The Accipitrinae are the Family (biology), subfamily of the Accipitridae often known as the "true" hawks. The subfamily contains 73 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Double-toothed Kite
The double-toothed kite (''Harpagus bidentatus'') is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found from central Mexico through Central America into much of northern and eastern South America.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F.

Harpagus (bird)
''Harpagus'' is a genus of birds of prey in the family Accipitridae. It comprises: Both live in tropical American forest. They are small, rather accipiter-like kites A kite is a tethered heavier than air flight, heavier-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have ..., 30 to 35 cm long and compact, with long tails and oval wings ("pinched in" near the base of the trailing edge) which they characteristically curve downward when soaring or gliding. Both have dark tails with pale bars, as well as a white throat with a dark stripe down the middle. Another shared feature is a blunt bill with two notches on each side of the upper mandible. This "double tooth" gave rise not only to the common name of one species but to the specific epithets ''bidentatus'' and ''diodon''. Both like rather high perches in trees and sometime ...

Semicollared Hawk
The semicollared hawk (''Microspizias collaris'') is a rare bird of prey species in the family Accipitridae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is potentially being affected by habitat loss. Taxonomy Formerly placed in the genus ''Accipiter'', it is the sister species of the tiny hawk (''M. superciliosus''). The latter was thought to be the only species in ''Accipiter'' yet studied which has a large procoracoid foramen. The ''collaris-superciliosus'' superspecies also differs from the typical sparrowhawks in other respects of its anatomy and as regards DNA sequence. Consequently, the old genus '' Hieraspiza'' may be more appropriate for them. In 2021, a phylogenetic study found it and the semicollared hawk to form a distinct group from the rest of ''Accipiter'', that is sister to ''Kaupifalco''. For this reason, both were reclassified into the new genus '' Microspizias''. It was formerl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buteoninae
The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species. They have large, powerful, hooked beaks for tearing flesh from their prey, strong legs, and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance. This subfamily contains the buzzards (buteonine hawks) with great diversity in appearance and form and some appearing eagle-like, with at least 50 species included overall in the subfamily. At one time, several types were grouped, including large assemblages such as booted eagles, but modern studies using mitochondrial DNA clarified that this subfamily was smaller than formerly classified. Systematics The subfamily Buteoninae was introduced (as "Buteonina") by the Irish zoologist Nicholas Vigors in 1825 with '' Buteo'' as the type genus. The subfamily includes about 79 currently recognized species. Unlike the many lineages of Accipitridae which seem to have radiated out ...

Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...

Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857) was a French naturalist and ornithology, ornithologist, and a nephew of Napoleon. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte (cardinal), Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I of France, Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde Laetitia Julie Bonaparte, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a Old World warbler, warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new Wilson's storm-petrel ...
