The southern banded snake eagle (Circaetus fasciolatus), also known as the East African snake eagle or fasciated snake eagle, is a species of snake eagle in the family Accipitridae which is found in eastern Sub-Saharan Africa.
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. [2]
The southern banded snake eagle is unobtrusive and is normally found due to its noisy, high-pitched call, "ko-ko-ko-kaw", repeatedly made either from a perch or while in flight. [2]
The southern banded snake eagle occurs in a narrow band along the east African coast from southern Somalia to the north eastern Kwazulu-Natal and inland along the Save River into south eastern Zimbabwe. [3]
The southern banded snake eagle is a forest species and it mainly occurs in evergreen coastal forest but also in dense inland forests close to wetlands, it is occasionally recorded from more open areas of woodland. [2]
As its name suggests, the southern banded snake eagle mainly eats snakes, hunting from a perch, scanning the surroundings for prey. If a large snake is caught, it is torn up into bite-size pieces before feeding; however, smaller snakes are swallowed whole, head-first. It has also been recorded feeding on lizards, frogs and termite alates. [4]
The nest is constructed by both sexes and is an open platform of small sticks roughly 50–70 cm wide with an inner cup which is 17 cm across and is lined with fresh foliage. The nest is normally placed in the main fork of a tree. The single egg is laid from August–October and is mainly incubated by the female for about 50 days, although the male may take over for short stints early on in the incubation period. Both parents feed the young on a diet of ripped up snakes. At first the male does the majority of the hunting, while the female looks after the nestling. [4]
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 knob-billed duck, or African comb duck, is a type of duck found along the tropical/sub-tropical wetlands and waterways of Sub-Saharan Africa and the island of Madagascar, as well as most of South Asia and mainland Indochina.
The plumbeous kite is a bird of prey in the family Accipitridae that is resident in much of northern South America. It is migratory in the northern part of its range which extends north to Mexico. It feeds on insects which it catches either from a perch or while in flight.
The black-chested snake eagle or black-breasted snake eagle 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.
The malachite sunbird is a small nectarivorous bird found from the highlands of Ethiopia southwards to South Africa. They pollinate many flowering plants, particularly those with long corolla tubes, in the Fynbos.
The banded kestrel is a bird of prey belonging to the falcon family Falconidae. It is endemic to Madagascar and is also known as the Madagascar banded kestrel, barred kestrel or Madagascar barred kestrel. Its closest relatives are the grey kestrel and Dickinson's kestrel of mainland Africa and the three are sometimes placed in the subgenus Dissodectes.
The pale chanting goshawk is a bird of prey in the family Accipitridae. This hawk breeds in southern Africa and is a resident species of dry, open semi-desert with 75 cm or less annual rainfall. It is commonly seen perched on roadside telephone poles.
The southern double-collared sunbird or lesser double-collared sunbird is a small passerine bird which breeds in southern Africa. It is mainly resident, but partially migratory in the north-east of its range.
The little sparrowhawk 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.
The African goshawk is an African species of bird of prey in the genus Accipiter which is the type genus of the family Accipitridae.
The red-necked buzzard, also known as the African red-tailed buzzard, is a species of buzzard in the family Accipitridae which is found in western and northern central Africa.
The brown snake eagle 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.
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.
The gabar goshawk is a small species of African and Arabian bird of prey in the family Accipitridae.
The black-crowned sparrow-lark is a species of lark in the family Alaudidae. It is found across northern Africa from Mauritania through the Middle East to north-western India. Its natural habitat is dry savanna.
Bates's nightjar or the forest nightjar, is a bird species of the family Caprimulgidae, found in the rainforests of western Sub-Saharan Africa.
The akun eagle-owl is a species of owl in the family Strigidae, native to the African tropical rainforest.
The brown-hooded kingfisher is a species of bird in the subfamily Halcyoninae, the tree kingfishers. It has a brown head and blackish and turquoise wings. It is found in Sub-Saharan Africa, living in woodland, scrubland, forest edges, and also suburban areas. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
The western banded snake eagle 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.
Beaudouin's snake eagle 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".
