Accipiter
''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] |
Northern Goshawk
The northern goshawk (; ''Accipiter gentilis'') is a species of medium-large raptor in the family Accipitridae, a family which also includes other extant diurnal raptors, such as eagles, buzzards and harriers. As a species in the genus '' Accipiter'', the goshawk is often considered a "true hawk". The scientific name is Latin; ''Accipiter'' is "hawk", from ''accipere'', "to grasp", and ''gentilis'' is "noble" or "gentle" because in the Middle Ages only the nobility were permitted to fly goshawks for falconry. This species was first described by Linnaeus in his ''Systema naturae'' in 1758 as ''Falco gentilis''. It is a widespread species that inhabits many of the temperate parts of the Northern Hemisphere. The northern goshawk is the only species in the genus ''Accipiter'' found in both Eurasia and North America. It may have the second widest distribution of any true member of the family Accipitridae, behind arguably only the golden eagle (''Aquila chrysaetos''), which has ...

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 ...

Goshawk
Goshawk may refer to several species of birds of prey, mainly in the genus ''Accipiter'': * Northern goshawk, ''Accipiter gentilis'', often referred to simply as the goshawk, since it is the only goshawk found in much of its range (in Europe and North America) * Crested goshawk, ''Accipiter trivirgatus'' * Sulawesi goshawk, ''Accipiter griseiceps'' * Red-chested goshawk, ''Accipiter toussenelii'' * African goshawk, ''Accipiter tachiro'' * Imitator goshawk, ''Accipiter imitator'' * Grey goshawk, ''Accipiter novaehollandiae'' * Brown goshawk, ''Accipiter fasciatus'' ** Christmas goshawk, ''Accipiter (fasciatus) natalis'' * Black-mantled goshawk, ''Accipiter melanochlamys'' * Slaty-mantled goshawk ''Accipiter luteoschistaceus '' * Pied goshawk, ''Accipiter albogularis'' * Fiji goshawk, ''Accipiter rufitorques'' * White-bellied goshawk, ''Accipiter haplochrous'' * Moluccan goshawk, ''Accipiter henicogrammus'' * Grey-headed goshawk, ''Accipiter poliocephalus'' * New Britain goshawk, ...

Little Sparrowhawk
The little sparrowhawk (''Accipiter minullus'') is a species of Afrotropical bird of prey in the family Accipitridae. It is the smallest member of the genus ''Accipiter'' and forms a superspecies with the red-thighed sparrowhawk (''Accipiter erythropus''). Description The little sparrowhawk is, as its name suggests a very small bird of prey which is also distinguished by two white spots on the underside of its central tail feathers and by a narrow white patch on the lower rump. It is sexually dimorphic and the male has dark grey upperparts, which can appear almost black, this colour extending on to the cheeks to contrast with the white throat. The underparts are white barred with fine rufous bars. The females are overall browner on the upperparts and the underpart bars are also browner and less fine than the male. The juveniles are browner overall with pale tips to the upperpart feathers and is spotted with grown below rather than barred and the rump feathers have only the tips ...

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 phylog ... [...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] |
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 frogm ...

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 ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...
