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 study found them to be strongly phylogenetically distinct, and thus described a new genus (''Microspizias'') for them. This was also followed by the International Ornithological Congress. 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 subfamily of the Accipitridae often known as the "true" hawks, including all members of '' Accipiter'' and the closely related genera ''Microspizias'', '' Erythrotrior ...

Tiny Hawk
The tiny hawk (''Microspizias superciliosus'') is a small diurnal bird of prey found in or near forests, primarily humid, throughout much of the Neotropics. It is primarily a bird-eater, and is known to prey on hummingbirds. Taxonomy The tiny hawk was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his '' Systema Naturae'' under the binomial name ''Falco superciliosus''. Linnaeus specified the locality as Suriname. The specific epithet ''superciliosus'' is Latin meaning "eye-browed". There are two subspecies separated by the northern Andes. The two differ most significantly in relative tail length; differences in size and color are small, and can be hard to distinguish. *''A. s. superciliosus'' is found east of the Andes in South America. Slightly the larger of the two subspecies, it is paler and has diffuse, grayish barring on the underparts. *''A. s. fontanieri'' is found from Nicaragua down to western Ecuador. It is somewhat ...

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 former ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accipitrinae
The Accipitrinae are the subfamily of the Accipitridae often known as the "true" hawks, including all members of ''Accipiter'' and the closely related genera ''Microspizias'', ''Erythrotriorchis'', and '' Megatriorchis''. The large and widespread genus ''Accipiter'' includes goshawks, sparrowhawks, the sharp-shinned hawk and others. They are primarily woodland birds that hunt by sudden dashes from a concealed perch, with long tails, broad wings and high visual acuity facilitating this lifestyle. In light of recent genetic research, the kites of the traditional subfamily Milvinae may also belong to this group. Hawks, including the accipitrines, are believed to have vision several times sharper than humans, in part because of the great number of photoreceptor cells in their retinas (up to 1,000,000 per square mm, against 200,000 for humans), a very high number of nerves connecting the receptors to the brain, and an indented fovea, which magnifies the central portion of the visual ...

Accipitridae
The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds 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 255 species which are divided into 70 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 group. Systematics and phylogeny ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard Buzzard
The lizard buzzard (''Kaupifalco monogrammicus'') or lizard hawk, is a bird of prey in the family Accipitridae. It is native to Sub-Saharan Africa. Despite its name, it may be more closely related to the ''Accipiter'' hawks than the ''Buteo'' buzzards. Taxonomy Molecular phylogenetic studies have revealed that the lizard buzzard is not closely related to ''Buteo'' buzzards but rather to ''Accipiter'' hawks. This extends to morphological associations, e.g. the lizard buzzard has pointed and fairly short wings. Despite the lizard buzzard inhabiting Africa, phylogenetic evidence indicates that its closest relatives are the two ''Microspizias'' hawks of Central and South America.'''' Description The lizard buzzard is a smallish stocky raptor with a total body length of 35–37 cm and a wingspan of about 79 cm. Males weigh 246 g, females 304 g on average. The upperparts, head and breast are grey. There is a vertical black line on the white throat, which distinguishes this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward C
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned. ...

Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Accipiter
''Accipiter'' is a genus of Bird of prey, birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species (excepting the northern goshawk) are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a coracoid, procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus ''Hieraspiza''.Olson (2006) Extant accipiters range in size from the little sparrowhawk (''A. minullus''), in which the smallest males measure long, span across the wings and weigh , to the northern goshawk (''A. gentilis''), in which the largest females measure long, span across the wings, and weigh . These birds are slender with short, broad, rounded wings and a long tail which helps them mane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Ornithologists' Union
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
