The long-tailed hawk (Urotriorchis macrourus) is an African bird of prey in the family Accipitridae. It is the only member of the genus Urotriorchis. [2]
The long-tailed hawk is a distinctively shaped raptor with a very noticeable long, barred tail and is dark grey on its upperparts and chestnut on its underparts with a contrasting white throat and undertail coverts. In flight the white flight feathers on the underwing are heavily barred with dark grey. There is a rare morph which has a grey breast, with a paler grey throat but still has the white undertail coverts. The bill is black, the eyes, cere, legs and feet are yellow. Juveniles are browner, with a white-breasted "plain" morph and a "marked" morph which has the breast streaked with brown. [3] It has a wingspan of 81–90 centimetres (32–35 in) and a total length of 56–65 centimetres (22–26 in), including the tail of 30–37 centimetres (12–15 in). [2] Females are about 15% larger than males. [2] Since the tail comprises about 56% of this raptor's total length, this species ties with the cinereous harrier as the raptor with the longest tail relative to its body size. [2]
It is a rather vocal bird which is often first detected by the long drawn out screech given by birds perched in the canopy. [3]
The long-tailed hawk occurs in the tropical rainforests of western and central Africa, from Guinea in the west, along the Gulf of Guinea coast south to northern Angola, east to the southern Central African Republic, northern Democratic Republic of Congo, South Sudan and western Uganda. [2]
The long-tailed hawk primarily eats squirrels, especially scaly-tailed squirrels, and small birds; it can also hunt chickens in the villages close to the forest. It kills prey by breaking the neck. It has also been known to attack hammer-headed fruit bats. Its strong legs and feet suggest its main prey are mammals. The mating season occurs in July and August, when the pair build a nest on a high tree. Little is known regarding nesting and breeding the young, [4] an adult was seen feeding a fledged juvenile in Sierra Leone in August. [5]
The generic name Urotriorchis was coined by Richard Bowdler Sharpe in 1874 and combines "Uro-", from the Greek "tail", [6] and "triorchis", a kind of hawk thought to have three testicles—for further details see Eutriorchis . "Macro-" is from the Greek for "long", so macrourus means "long-tailed", as in the English name. [6]
The Pallid Harrier is a migratory bird of prey of the harrier subfamily. The scientific name is derived from the Ancient Greek. Circus is from kirkos, referring to a bird of prey named for its circling flight, probably the hen harrier and macrourus is "long-tailed", from makros, "long" and -ouros "-tailed".
The sharp-shinned hawk or Northern sharp-shinned hawk, commonly known as a sharpie, is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk, plain-breasted hawk, and rufous-thighed hawk. The American Ornithological Society keeps all four variations conspecific.
The African harrier-hawk, harrier hawk or gymnogene is a bird of prey. It is about 60–66 centimetres (24–26 in) in length. It breeds in most of Africa south of the Sahara. The only other member of the genus is the allopatric Madagascar harrier-hawk.
The changeable hawk-eagle(Nisaetus cirrhatus) or crested hawk-eagle is a large bird of prey species of the family Accipitridae. More informal or antiquated English common names include the marsh hawk-eagle or Indian crested hawk-eagle. It is a member of the subfamily Aquilinae, with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus. It was formerly placed in the genus Spizaetus, but studies pointed to the group being paraphyletic resulting in the Old World members being placed in Nisaetus and separated from the New World species. It is a typical “hawk-eagle” in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between birds, mammals or reptiles as well as other vertebrates. Among the members of its genus, the changeable hawk-eagle stands out as the most widely distributed, adaptable and abundant species. Individuals show a wide range of variation in plumage from pale to dark, varying with moult and age giving rise to the name "changeable".
The long-legged buzzard is a bird of prey found widely in several parts of Eurasia and in North Africa. This species ranges from Southeastern Europe down to East Africa to the northern part of the Indian subcontinent. The long-legged buzzard is a member of the genus Buteo, being one of the larger species therein. Despite being relatively powerful, it is considered a rather sluggish raptor overall. Like most buzzards, it prefers small mammals such as rodents, including gerbils, ground squirrels, voles and rats, also taking reptiles, birds and insects as well as carrion. Adaptable to a variety of habitats, long-legged buzzards may nest on a variety of surfaces, including rocks, cliffs and trees. it is a typical buzzard in its reproductive biology. The long-legged buzzard is widely distributed and appears to be quite stable in population. Therefore, it is considered as Least Concern by the IUCN.
The gray-headed kite is a raptor found in open woodland and swamp forests. It shares the genus Leptodon with the extremely rare white-collared kite. It breeds from eastern Mexico and Trinidad south to Peru, Bolivia, Brazil and northern Argentina.
The Malagasy kestrel, also known as the Madagascar kestrel, Malagasy spotted kestrel, Newton's kestrel, Madagascar spotted kestrel, katiti (Creole) or hitsikitsika (Malagasy), is a small bird of prey of the genus Falco. It is named after British ornithologist Edward Newton. It occurs in two subspecies on Madagascar and at Aldabra. The race from Aldabra is also called Aldabra kestrel. Its closest living relative is the Seychelles kestrel; they were at one time considered conspecific. Their common ancestors appear to have diverged very recently, probably less than 1 million years ago during the Early or Middle Pleistocene. The Mauritius kestrel is more distantly related.(Groombridge et al. 2002)
The Pacific baza, also known as the crested hawk, crested baza, and Pacific cuckoo-falcon, is a slender, medium-sized species of hawk in the family Accipitridae. It is mostly grey, brown, and white coloured and grows to a length of 35–46 centimetres (14–18 in). It is an omnivore and usually does not migrate. The breeding season for the species lasts from September to at least February, during which time specimens commonly fly and vocalise for display. It lives in Australia, Indonesia, Papua New Guinea, Solomon Islands, and East Timor, in forests, savannas, and freshwater bodies. The International Union for Conservation of Nature lists it as a least concern species.
The hooded mannikin or hooded munia, also known as the New Britain mannikin or Sclater's mannikin, is a species of estrildid finch found in New Britain and New Guinea.
The eastern (pale) chanting goshawk, or Somali chanting goshawk, is a bird of prey of East Africa.
The augur buzzard is a fairly large African bird of prey. This species is distinct in typical adult plumage for its blackish back, whitish underside and orange-red tail, while juvenile augur buzzards are generally rather brown in colour; however a dark morph is known, which causes the bird's entire body to become darker. This member of the Buteo genus is distributed in several parts of the central and southern Africa, normally being found from Ethiopia to southern Angola and central Namibia. It is resident and non-migratory throughout its range. This is a species of mountains, and adjacent savannah and grassland. This is a typical buteonine raptor, being a generalist predator which tends to prefer small mammals supplemented by reptiles and birds among various prey items.
The rufous-winged buzzard is an Asian bird of prey. It is a resident breeder of Indochina, Java and Sulawesi. It is a species of deciduous forest and second growth up to 800 m.
The Congo serpent eagle is a species of bird of prey in the family Accipitridae. It is the only member of the monotypic genus Dryotriorchis, although it was formerly placed in Circaetus. This species is distributed across the African tropical rainforest, including upper and lower Guinean forests. This serpent eagle specializes in hunting in these forests’ dark understories. It has two subspecies, the nominate subspecies Dryotriorchis spectabilis spectabilis and Dryotriorchis spectabilis batesi. Though monotypic, it appears to be very closely related to Circaetus. This hawk is a medium-sized bird with distinctive short, rounded wings and a long, rounded tail. It is varying shades of brown on its back and has a slight crest. Its breast is white with variable amounts of a rufous wash and, in the nominate subspecies, is covered in round, blackish spots. The subspecies D. s. batesi only has these dots on its flanks. The Congo serpent eagle closely resembles Cassin's hawk-eagle, and some ornithologists believe that this likeness is a rare example of avian mimicry. It is a very vocal raptor, and often is one of the most heard species in its habitat.
Ayres's hawk-eagle, also referred to as Ayres' eagle, is a medium-sized bird of prey in the family Accipitridae. It is native to African woodlands. Its name honors South African ornithologist Thomas Ayres.
The Madagascar harrier-hawk is a very large species of bird of prey in the family Accipitridae, endemic to Madagascar.
Cassin's hawk-eagle or Cassin's eagle, is a relatively small eagle in the family Accipitridae. Its feathered legs mark it as member of the Aquilinae or booted eagle subfamily. A forest-dependent species, it occurs in primary rainforests across western, central and (marginally) eastern Africa where it preys on birds and tree squirrels. It was named after John Cassin who first described it in 1865. Due to widespread habitat destruction, its populations are steadily declining but have not yet warranted upgrading its status from Least Concern.
The black-throated coucal is a species of cuckoo in the family Cuculidae. It is found in West Africa in dense second growth along forest edge and grassy swamps. The subspecies found in northern and central Zaire is sometimes split as Neumann's coucal.
The African cuckoo is a species of cuckoo in the family Cuculidae. It is found in Sub-Saharan Africa where it migrates within the continent, generally arriving and breeding in any one locality during the rainy season. A fairly common bird, the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Archbold's newtonia is a species of bird in the family Vangidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. The birds have a greyish brown back and tail, with a rufous forecrown and a buffy white belly, throat, and undertail coverts. They have a conspicuous rufous eye-ring, accompanied with a black bill and pale yellow eyes. The species is sexually monomorphic, and there is no major difference between the sexes. There is no breeding plumage for the males.
The black-fronted bushshrike is a passerine bird of the bushshrike family, Malaconotidae. It inhabits forests mainly in East Africa. It forms a superspecies with the many-colored bushshrike and the two are sometimes considered to be a single species.
