Accipiter Brevipes MHNT
''Accipiter'' is a genus of 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 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 maneuver in flight. They ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collared Sparrowhawk
The collared sparrowhawk (''Accipiter cirrocephalus'') is a small, slim bird of prey in the family Accipitridae found in Australia, New Guinea and nearby smaller islands. As its name implies the collared sparrowhawk is a specialist in hunting small birds. It is characterised by its slight brow ridges and slender feet. The last segment of their middle toe projects beyond the claws of the other toes. Description The collared sparrowhawk is 29–38 cm (tail about half ), with a wingspan 55–78 cm, the average male weighs 126 g, female 218 g. They are small, fierce, finely built with rounded wings, long square tail, yellow eyes and long legs. Adults have slate-grey upper parts, sometimes with a brown wash, and a chestnut half collar. The underparts are finely barred rufous and white. The under wing and tail are finely barred. The cere is cream to olive-yellow, the eyes yellow and the legs and feet yellow. The sexes are similar in appearance but males are smaller than fem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Sparrowhawk
The Eurasian sparrowhawk (''Accipiter nisus''), also known as the northern sparrowhawk or simply the sparrowhawk, is a small bird of prey in the family Accipitridae. Adult male Eurasian sparrowhawks have bluish grey upperparts and orange-barred underparts; females and juveniles are brown above with brown barring below. The female is up to 25% larger than the male – one of the greatest size differences between the sexes in any bird species. Though it is a predator which specialises in catching woodland birds, the Eurasian sparrowhawk can be found in any habitat and often hunts garden birds in towns and cities. Males tend to take smaller birds, including tits, finches, and sparrows; females catch primarily thrushes and starlings, but are capable of killing birds weighing or more. The Eurasian sparrowhawk is found throughout the temperate and subtropical parts of the Old World; while birds from the northern parts of the range migrate south for winter, their southern count ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Sundas Goshawk
The Lesser Sundas goshawk (''Accipiter hiogaster sylvestris'') is a bird of prey native to Indonesia. It is sometimes elevated to species status, but the IOC lumps it together with the variable goshawk The variable goshawk (''Accipiter hiogaster'') is a bird of prey native to Indonesia, Papua New Guinea and the Solomon Islands. It was recently elevated to species status, and was previously lumped together with the grey goshawk The grey gos ... (''A. hiogaster'').

Circus (bird)
A harrier is any of the several species of diurnal hawks sometimes placed in the subfamily Circinae of the bird of prey family Accipitridae. Harriers characteristically hunt by flying low over open ground, feeding on small mammals, reptiles, or birds. The young of the species are sometimes referred to as ring-tail harriers. They are distinctive with long wings, a long narrow tail, the slow and low flight over grasslands and skull peculiarities. The harriers are thought to have diversified with the expansion of grasslands and the emergence of grasses about 6 to 8 million years ago during the Late Miocene and Pliocene. Taxonomy The genus ''Circus'' was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The type species was subsequently designated as the western marsh harrier. Most harriers are placed in this genus. The word ''Circus'' is derived from the Ancient Greek ''kirkos'', referring to a bird of prey named for its circling flight (''kirkos'', "c ...
