Banded Snake-eagle
''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] |
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] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Western Banded Snake Eagle (Circaetus Cinerascens)
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] |
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, ...

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.

Brown Snake Eagle, Kruger National Park (38184851511)
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn. Etymology The term is from Old English , in origin for any dusky or dark shade of color. The first recorded use of ''brown'' as a color name in English was in 1000. The Common Germanic adjectives ''*brûnoz and *brûnâ'' meant b ...

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] |
