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 ...

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 Spilornis cheela, 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 that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by th ... birds because they are mostly found in Asia and Africa.

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 Palawan (), officially the Province of Palawan ( cyo, Probinsya i'ang Palawan; tl, Lalawigan ng Palawan), is an archipelagic province of the Philippines that is located in the region of Mimaropa.

Mountain Serpent Eagle
The mountain serpent eagle (''Spilornis kinabaluensis''), also known as the Kinabalu serpent eagle, is a bird of prey that is found in northern Borneo. It is found at altitudes of in forest, especially where it becomes dwarf forest, stunted. Where their range overlaps, the crested serpent eagle generally occurs at lower altitudes. The mountain serpent eagle is darker than the Bornean subspecies of the crested serpent eagle. The mountain serpent eagle is threatened by habitat loss. However, they occur within the Kinabalu National Park and the Gunung Mulu National Park. Their high-altitude habitats are usually too remote for logging and agriculture, making some of its range secure. References * Ferguson-Lees & Christie (2001). ''Raptors of the World.''

Accipitridae
The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds 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 255 species which are divided into 70 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 group. Systematics and phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
