Snake-eagle
Circaetinae is a bird of prey subfamily which consists of a group of medium to large broad-winged species. These are mainly birds which specialise in feeding on snakes and other reptiles, which is the reason most are referred to as "snake-eagles" or "serpent-eagles". The exceptions are the bateleur, a more generalised hunter, and the Philippine eagle, which preys on mammals and birds. All but one of the subfamily are restricted to warmer parts of the Old World: ''Spilornis'' and ''Pithecophaga'' in south Asia, the others in Africa. The short-toed eagle ''Circaetus gallicus'' migrates between temperate Eurasia and Africa, as well as being resident in India. They have hooked beaks for tearing flesh from their prey, strong legs and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance.

Southern Banded Snake Eagle
The southern banded snake eagle, also known as the East African snake eagle or fasciated snake eagle (''Circaetus fasciolatus'') is a species of snake eagle in the family Accipitridae which is found in eastern Sub-Saharan Africa. Description The Southern banded snake eagle is a rather small, stocky snake eagle with a large, rounded head which has a hooded beak. It has a grey-brown head contrasting slightly with the mainly blackish-brown upperparts and whitish underparts. The tail has a white tip and shows three distinct dark bands on the underside. The large eyes are pale yellow eyes, the feet and cere are yellow and the bill us black. The juvenile lacks the grey head, has mainly dark upperparts and the whitish pale underparts are marked with dark streaks on the face, throat and upper breast. The total length varies from 55 to 60 cm with females larger than males. Voice The Southern banded snake eagle is unobtrusive and is normally found due to its noisy, high-pitched call, ...

Black-chested Snake Eagle
The black-chested snake eagle or black-breasted snake eagle (''Circaetus pectoralis'') is a large African bird of prey of the family Accipitridae. It resembles other snake eagles and was formerly considered conspecific with the short-toed and Beaudouin's snake eagles, to which it is closely related. Taxonomy Although originally proposed as separate species, many authors previously considered both the black-chested and Beaudouin's snake eagles to be subspecies of the short-toed snake eagle (''Circaetus gallicus''). However, this convention was not followed by all taxonomists, with some citing differences in adult plumage and breeding ranges as evidence in favour of awarding each full species status. Brown (1974) followed this latter view, but cited several instances of alleged hybridization between the three forms which would justify their treatment as a single species under the Biological Species Concept. However, Clark (1999) suggested that these alleged hybridization events ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Banded Snake Eagle
The western banded snake eagle (''Circaetus cinerascens'') is a grey-brown African raptor with a short tail and a large head. Juveniles have paler and browner upper parts than adults, with white-edged feathers. The eagle's head, neck and breast are dark-streaked. The underparts are white with pale brown streaks, mainly on belly and thighs. Subadults may be all dark grey-brown without any streak on underparts. The eyes, ears, and legs are yellow. They have crested chests. Habitat Western banded snake eagles live in woodlands, mainly along rivers, but they avoid dense forests. Behaviour Western banded snake eagles mainly hunt snakes, but also other small vertebrates, ambushing from a perch. They drop from the perch to trunk, foliage or ground. They are solitary birds, and very secretive. Due to their sedentary lifestyle, they are often detected only by their calls. The western banded snake eagle sometimes rises to soar, while it calls above the canon. They utter a loud, high-p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Snake Eagle
The brown snake eagle (''Circaetus cinereus'') is a fairly large species of bird of prey in the family Accipitridae. It is found in West, East and southern Africa. This species is an almost obligate predator of a variety of snakes. A very solitary bird, the brown snake eagle has a prolonged breeding cycle and raises a single eaglet. Although probably naturally scarce, it is classified as a least concern species as it continues to occur over a very broad range. Distribution and habitat This species is distributed widely in Africa. In west Africa, ranges from southeastern Mauritania, Senegal, The Gambia, Guinea-Bissau, eastern and western Guinea, Sierra Leone, the northern, inland parts of Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria as well as inland in Mali and Niger. From there they range across to southern Chad, southern Sudan, South Sudan, inland in Eritrea and northern Ethiopia and central Ethiopia and in southern Somalia through much of Kenya, Uganda and the southern par ...

Beaudouin's Snake Eagle
Beaudouin's snake eagle (''Circaetus beaudouini'') is a species of snake eagle in the family Accipitridae found in the Sahel region of west Africa. It forms a superspecies with the Palearctic short-toed snake eagle ''Circaetus gallicus'' and the black-chested snake eagle ''Circaetus pectoralis''. This bird seems to be declining in numbers and the International Union for Conservation of Nature has rated it as a "vulnerable species". Description The bird has a wingspan of . A large snake eagle with grey-brown upperparts, including the head and chest, contrasting with white underparts barred with brown and white vent. It has a black bill and large, bright yellow eyes with long pale grey, unfeathered legs. Juveniles are all dark. Behaviour Normally seen on a prominent perch such as a telegraph pole or dead tree, as it is a sit-and-wait hunter, rather than in flight but generally behaviour is poorly known. The diet mainly consists of snakes and other small vertebrates. It breeds in N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crested Serpent Eagle
The crested serpent eagle (''Spilornis cheela'') is a medium-sized bird of prey that is found in forested habitats across tropical Asia. Within its widespread range across the Indian Subcontinent, Southeast Asia and East Asia, there are considerable variations and some authorities prefer to treat several of its subspecies as completely separate species.Ferguson-Lees, James & Christie, David A. (2001). ''Raptors of the World.'' Christopher Helm, London. In the past, several species including the Philippine serpent eagle (''S. holospila''), Andaman serpent eagle (''S. elgini'') and South Nicobar serpent eagle (''S. klossi'') were treated as subspecies of the Crested serpent eagle. All members within the species complex have a large looking head with long feathers on the back of the head giving them a maned and crested appearance. The face is bare and yellow joining up with the ceres while the powerful feet are unfeathered and heavily scaled. They fly over the forest canopy on broad ...

Short-toed Snake Eagle
The short-toed snake eagle (''Circaetus gallicus''), also known as the short-toed eagle, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. The genus name ''Circaetus'' is from the Ancient Greek ''kirkos'', a type of hawk, and ''aetos'', "eagle". The specific ''gallicus'' means "of Gallia". Taxonomy The short-toed snake eagle was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the falcons, eagles and their relatives in the genus '' Falco'' and coined the binomial name ''Falco gallicus''. Gmelin based his description on the "Jean le Blanc" that had been described by the English ornithologist John Latham and the French ornithologists Mathurin Jacques Brisson and the Comte de Buffon. The short-toed snake eagle is now placed in the genus ''Circaetus'' that was introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circaetus
''Circaetus'', the snake eagles, is a genus of medium-sized eagles in the bird of prey family Accipitridae. They are mainly resident African species, but the migratory short-toed snake eagle breeds from the Mediterranean basin into Russia, the Middle East and India, and winters in sub-Saharan Africa and east to Indonesia. Snake eagles are found in open habitats like cultivated plains arid savanna, but require trees in which to build a stick nest. The single egg is incubated mainly or entirely by the female. ''Circaetus'' eagles have a rounded head and broad wings. They prey on reptiles, mainly snakes, but also take lizards and occasionally small mammals. Taxonomy and species The genus ''Circaetus'' was introduced in 1816 by the French ornithologist Louis Jean Pierre Vieillot to accommodate a single species, the short-toed snake eagle, which is therefore considered the type species. The genus name is from the Ancient Greek Ancient Greek includes the forms of the Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine Eagle
The Philippine eagle (''Pithecophaga jefferyi''), also known as the monkey-eating eagle or great Philippine eagle, is a critically endangered species of eagle of the family Accipitridae which is endemic to forests in the Philippines. It has brown and white-colored plumage, a shaggy crest, and generally measures in length and weighs . The Philippine eagle is considered the largest of the extant eagles in the world in terms of length and wing surface area, with only Steller's sea eagle and the Harpy eagle being larger in terms of weight and bulk. It has been declared the national bird of the Philippines.Kennedy, R. S., Gonzales, P. C.; Dickinson, E. C.; Miranda, H. C. Jr. and Fisher, T. H. (2000). ''A Guide to the Birds of the Philippines.'' Oxford University Press, New York. The most significant threat to the species is loss of habitat, a result of high levels of deforestation throughout most of its range. Killing a Philippine eagle is a criminal offence, punishable by law w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terathopius
The bateleur (; ''Terathopius ecaudatus'') is a medium-sized eagle in the family Accipitridae. It is often considered a relative of the snake eagles and, like them, it is classified within the subfamily Circaetinae.Kemp, A. C., G. M. Kirwan, and D. A. Christie (2020). ''Bateleur (Terathopius ecaudatus)'', version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. It is the only member of the genus ''Terathopius'' and may be the origin of the "Zimbabwe Bird", the national emblem of Zimbabwe. Adult bateleurs are generally black in colour with a chestnut colour on the mantle as well as also on the rump and tail. Adults also have gray patches about the leading edges of the wings (extending to the secondaries in females) with bright red on their cere and their feet. Adults also show white greater coverts, contrasting with black remiges in males, gray patches on the underwing primarie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
