Accipiter
''Accipiter'' () is a genus of birds of prey in the family Accipitridae. Some species are called sparrowhawks, but there are many sparrowhawks in other genera such as '' Tachyspiza''. These birds are slender with short, broad, rounded wings and a long tail which helps them maneuver in flight. They have long legs and long, sharp talons used to kill their prey, and a sharp, hooked bill used in feeding. Females tend to be larger than males. They often ambush their prey, mainly small birds and mammals, capturing them after a short chase. The typical flight pattern is a series of flaps followed by a short glide. They are commonly found in wooded or shrubby areas. The genus ''Accipiter'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The type species is the Eurasian sparrowhawk (''Accipiter nisus''). The name is Latin for "hawk", from ''accipere'', "to grasp".

Accipiter Nisus
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 Tit (bird), tits, finches and Old World sparrow, sparrows; females catch primarily Thrush (bird), 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; whilst birds from the northern parts of the range Bird mig ...

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] |
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] |
Astur (genus)
''Astur'' is a genus containing hawks, goshawks and sparrowhawks in the family Accipitridae. The species were formerly placed in the genus ''Accipiter''. Taxonomy The genus ''Astur'' was introduced in 1799 by the French naturalist Bernard Germain de Lacépède. The type species was later designated by the Irish zoologist Nicholas Vigors as ''Falco palumbarius'' Linnaeus, 1758, now considered as a junior synonym of ''Falco gentilis'' Linnaeus, 1758, the Eurasian goshawk. The name is from Latin ''astur'', ''asturis'' meaning "hawk". Species now placed in this genus were formerly assigned to the genus ''Accipiter''. Molecular phylogenetic studies found that ''Accipiter'' was polyphyletic and in the subsequent rearrangement to create monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most ...

Ovambo Sparrowhawk
The Ovambo or Ovampo sparrowhawk, also known as Hilgert's sparrowhawk, (''Accipiter ovampensis'') is a species of sub-Saharan African bird of prey in the family Accipitridae. It takes its name from the Ovamboland in northern Namibia. Description The Ovambo sparrowhawk is a small sparrowhawk with the typical broad winged, long-tailed shape of a member of the genus ''Accipiter''. The adults have plain grey upperparts with white bars on the rump and white underparts which are finely barred with grey but with a plain white vent. The tail has three dark bars and a broad, dark subterminal band. The bill is black, contrasting with the red cere, the eyes are dark red and the legs are orange. There is a melanistic form which is all black except for the white barred flight feathers on the underwing. The juvenile is browner and may be white over the underparts and head or have a brown head and rufous underparts. Females are about 14% bigger than males, weighing in at to the males . The tota ...

Crested Goshawk
The crested goshawk (''Lophospiza trivirgata'') is a bird of prey in the family Accipitridae that is widely distributed in tropical Asia. It was formerly placed in the genus ''Accipiter''. Taxonomy The crested goshawk was formally described in 1824 by the Dutch zoologist Coenraad Jacob Temminck under the binomial name ''Falco trivirgatus''. The 5 volumes were originally issued in 102 ''livraison'' (parts), 1820-1839. For the dates see: It was formerly placed in the very large genus ''Accipiter''. When molecular phylogenetic studies found that ''Accipiter'' was polyphyletic, the genus was split to create monophyletic genera. As part of this reorganisation, the genus '' Lophospiza'' which was erected in 1844 by the German naturalist Johann Jakob Kaup was resurrected to accommodate the crested goshawk and the closely related Sulawesi goshawk. The specific epithet ''trivirgata'' combines the Latin ''tri'' meaning "three" with ''virgatus '' meaning "striped". Eleven subspecies are ...

Aerospiza
''Aerospiza'' is a genus containing goshawks and a sparrowhawk in the family Accipitridae that are found in Africa. The two species in the genus were formerly placed in the genus ''Accipiter''. Taxonomy The genus ''Aerospiza'' was introduced in 1922 by the South African zoologist Austin Roberts with ''Falco tachio'', Daudin, 1800 (the African goshawk) as the type species. The name combines the Ancient Greek αηρ (''aēr''), αερος (''aeros'') meaning "air" with σπιζιας (''spizias'') meaning "hawk". Species now placed in this genus were formerly assigned to the genus ''Accipiter''. Molecular phylogenetic studies found that ''Accipiter'' was polyphyletic and in the subsequently rearrangement to create monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent co ... gen ...

Lophospiza
''Lophospiza'' is a genus of Asian birds of prey in the family Accipitridae. It is the only genus in the subfamily Lophospizinae. The two species placed in this genus were formerly placed in the genus ''Accipiter''. Taxonomy The genus ''Lophospiza'' was introduced in 1844 by the German naturalist Johann Jakob Kaup with ''Falco trivirgatus'' Temminck as the type species. The name combines the Ancient Greek λοφος (''lophos'') meaning "crest" and σπιζιας (''spizias'') meaning "hawk". The genus contains two species: * Crested goshawk, ''Lophospiza trivirgata'' * Sulawesi goshawk, ''Lophospiza griseiceps'' Both species were formerly classified in the genus ''Accipiter'' but molecular phylogenetic studies found that ''Accipiter'' was polyphyletic. In the rearrangement to create monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which m ...
