Sumba hornbill (Latin : Rhyticeros everetti), or known natively as Julang (in Sumba languages) is a large bird belonging to the family of Bucerotidae , endemic and native to the Indonesian island of Sumba. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett.
It is a medium-sized, blackish hornbill, approximately 70 cm long. The male is dark reddish-brown on the crown and nape, with a paler neck. The female has entirely black plumage. Both sexes have a large, dull, yellowish bill with a maroon patch at the base, a serrated casque, and an inflatable blue throat.
An Indonesian endemic, the Sumba hornbill inhabits semi-evergreen forests of Sumba in the Lesser Sunda Islands. It is uncommon and found in the lowlands at altitudes of up to 950 m (3,120 ft).
The Sumba hornbill is a monogamous species. Its diet consists mainly of fruits.
Due to ongoing habitat loss, limited range, small population size and overhunting in some areas, the Sumba hornbill is assessed as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES. Part of its habitat is protected in the Laiwangi Wanggameti National Park and the Manupeu Tanah Daru National Park. [1]
Sumba, natively also spelt as Humba, Hubba, Suba, or Zuba is an Indonesian island located in the Eastern Indonesia and administratively part of the East Nusa Tenggara provincial territory. Sumba has an area of 11,243.78 square kilometres, about the same size as Jamaica or Hawaii (Island). The population was 686,113 at the 2010 Census and 779,049 at the 2020 Census; the official estimate as of mid-2023 was 820,506. To the northwest of Sumba is Sumbawa, to the northeast, across the Sumba Strait, is Flores, to the east, across the Savu Sea, is Timor, and to the south, across part of the Indian Ocean, is Australia.
Hornbills are birds found in tropical and subtropical Africa, Asia and Melanesia of the family Bucerotidae. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a horny casque on the upper mandible. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, mainly in Southeast Asia.
The Philippine scops owl, also Luzon lowland scops owl is a common owl, endemic to the Philippines, belonging to the family of the typical owls Strigidae. Other common names include "Otus Whitehead", "Whitehead scops owl" and "Luzon lowland scops owl". Everett's scops owl and Negros scops owls were formerly considered conspecific but are now classified as separate species.
Narcondam, India's easternmost island, is a small volcanic island located in the northern Andaman Sea. The island's peak rises to 710 m above mean sea level, and it is formed of andesite. It is part of the Andaman Islands, the main body of which lie approximately 74 km (46 mi) to the west. The island is part of the Indian union territory of Andaman and Nicobar Islands. The island is small, covering an area of approximately 7.6 square kilometres. It was classified as a active volcano by the Geological Survey of India.
The wreathed hornbill is an Old World tropical bird of the hornbill family Bucerotidae, also called bar-pouched wreathed hornbill due to its distinctive blue-black band on its lower throat sac. It is named after its characteristic long, curved bill that develops ridges, or wreaths, on the casque of the upper mandible in adults. Males are black with a rufous crown, a white upper breast and face, and a yellow featherless throat. Females are uniformly black with a blue throat and are slightly smaller than males.
Blyth's hornbill, also known as the Papuan hornbill, is a large hornbill inhabiting the forest canopy in Wallacea and Melanesia. Its local name in Tok Pisin is kokomo.
The Palawan hornbill is a large forest bird endemic to the Philippines. It is one of the 11 endemic hornbills in the country. It is only found in Palawan and nearby islands of Balabac, Busuanga, Calauit, Culion and Coron. It is locally known as "talusi" in the language Cuyunon. It is threatened by habitat loss, hunting and trapping for the cage-bird trade.
The knobbed hornbill, also known as Sulawesi wrinkled hornbill, is a colourful hornbill native to Indonesia. The species is sometimes placed in the genus Aceros. The knobbed hornbill is the faunal symbol of South Sulawesi province.
The blue-backed parrot, also known as Müller's parrot and Burbridge's parrot is a large, endangered species of parrot endemic to the Philippines. It is found in tropical moist lowland forest but is now feared locally extinct in a large part of its range including Negros, Panay, Leyte, Luzon and Polilio. The only recent records are in Samar, Mindanao and Tawi-tawi. Flocks are small and often active at night. Its main threats are habitat loss and trapping for the pet trade.
The writhed hornbill, also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to primarily lowland forests on the Philippine islands of Mindanao, Dinagat and Camiguin Sur. It formerly included the Walden's hornbill as a subspecies, but unlike that species, both sexes of the writhed hornbill have orange-red throat and peri-ocular skin. The writhed hornbill is threatened by habitat loss and hunting.
The Narcondam hornbill is a species of hornbill in the family Bucerotidae. It is endemic to the Indian island of Narcondam in the Andamans. Males and females have a distinct plumage. The Narcondam hornbill has the smallest home range out of all the species of Asian hornbills.
The Luzon hornbill, sometimes called Luzon tarictic hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to forests on Luzon and nearby islands in the northern Philippines. All five Philippine tarictics were once considered a single species. It is declining due to habitat destruction, hunting and the illegal wildlife trade.
The Mindoro hornbill is a species of hornbill in the family Bucerotidae. It is endemic to forests on Mindoro in the Philippines found in tropical moist lowland forests. As is the case with all five Philippine tarictic hornbills, formerly considered to be just one species. It is the only tarictic hornbill where both sexes are creamy-white and black. The sexes are very similar, differing primarily in the colour of the ocular ring. It is threatened by habitat loss, and is consequently considered endangered by the IUCN.
The yellowish bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is endemic to the Philippines found only on East Visayas, Mindanao and the Sulu Archipelago. The birds of the Sulu archipelago are sometimes considered a separate species called the Sulu bulbul. This species is declining due to habitat loss.
The Sumba boobook is a species of owl in the family Strigidae. It is endemic to Sumba in the Lesser Sunda Islands of Indonesia. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest. It is threatened by habitat loss.
The least boobook, also known as the little Sumba hawk-owl or little Sumba boobook, is a species of owl in the family Strigidae. It is endemic to the Indonesian island of Sumba. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The Sumba buttonquail is a species of bird in the family Turnicidae. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett.
The black-bibbed cicadabird or black-bibbed cuckooshrike is a species of bird in the family Campephagidae. It is endemic to the Philippines. The species is elusive and poorly known. This species has five subspecies that differ considerably in plummage, it is possible that this may actually be a species complex and consists of multiple species.
The Sumba myzomela is a species of bird in the family Meliphagidae. It is endemic to Sumba in the western Lesser Sunda Islands of Indonesia, where it is found in forest with a significant component of deciduous trees.
Everett's scops owl is an owl, endemic to the Philippines, belonging to the family of the typical owls Strigidae. They are found on Bohol, Samar, Biliran, Leyte, Mindanao and Basilan. This species is part of the Philippine scops owl species complex which includes the Negros scops owl.
