Circaetinae
Circaetinae is a subfamily of the family Accipitridae which contains a group of medium to large broad-winged birds of prey. The group is sometimes treated as tribe Circaetini. These birds mainly 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. Taxonomy The subfamily Circaetinae was introduced in 1851 by the English zoologis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bateleur
The bateleur (; ''Terathopius ecaudatus''), also known as the bateleur eagle, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 Endemism, endemic to forests in the Geography of the Philippines, 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. It is also depicted in the Philippine one thousand-peso note.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.

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] [Amazon] |
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 bro ...

Congo Serpent Eagle
The Congo serpent eagle (''Circaetus spectabilis'') is a species of bird of prey in the family Accipitridae. 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 ''Circaetus spectabilis spectabilis'' and ''Circaetus spectabilis batesi''. 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 ''C. 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 hear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Andaman Serpent Eagle
The Andaman serpent eagle (''Spilornis elgini''), also known as the Andaman dark-serpent eagle or the dark serpent eagle, is a medium-sized bird in the family Accipitridae, the raptor family, that is only found in India on the Andaman Islands. It is currently classified as vulnerable and is experiencing population declines. This species, unlike the Crested serpent eagle, is incredibly understudied and so many things about its behaviour and ecology are still widely unknown. Taxonomy The genus ''Spilornis'' contains six species of serpent eagles, majority of which are island endemics. Serpent eagles are considered Old World The "Old World" () is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas.

Philippine Serpent Eagle
The Philippine serpent eagle (''Spilornis holospilus'') is an eagle found in the major islands of the Philippines. It is sometimes treated as a race of the crested serpent eagle (''Spilornis cheela''). This species is usually found in forest clearings, open woodlands, and sometimes in cultivated lands with scattered trees. It is endemic to the Philippines. The species is found on most part of the major islands, except for Palawan. It is illegal to hunt, capture or possess Philippine serpent eagles under Philippine Law RA 9147. Description and taxonomy Ebird describes it as "A fairly large, common raptor of forest and more open wooded areas from the lowlands to the lower mountains. Dark brown with white speckles on the crown and upperparts, rufous-brown below with large white spots. Note the gray cheek and yellow eye.
