Imitator Goshawk
The imitator goshawk (''Accipiter imitator'') or imitator sparrowhawk, is a species of bird of prey in the family Accipitridae. It is found on the islands of Bougainville, Choiseul and Santa Isabel in the Solomon Islands archipelago. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

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 phylogeny ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bougainville Island
Bougainville Island (Tok Pisin: ''Bogenvil'') is the main island of the Autonomous Region of Bougainville, which is part of Papua New Guinea. It was previously the main landmass in the German Empire-associated North Solomons. Its land area is . The population of the whole province, including nearby islets such as the Carterets, is approximately 300,000 (2019 census). The highest point is Mount Balbi, on the main island, at . The much smaller Buka Island, , lies to the north, across the wide Buka Strait. Even though the strait is narrow, there is no bridge across it, but there is a regular ferry service between the key settlements on either side. The main airport (or airstrip) in the north is in the town of Buka. Bougainville is the largest island in the Solomon Islands archipelago. Most of the islands in this archipelago (which are primarily concentrated in the southern and eastern portions of it) are part of the politically independent Solomon Islands. Two of these islands ...

Choiseul Island
Choiseul Island, native name Lauru, is the largest island () of the Choiseul Province, Solomon Islands, at . The administrative headquarters of Choiseul Province is situated in the town of Taro, on Taro Island. History In 1768, the French explorer Louis Antoine de Bougainville named the island after the then French foreign minister, Étienne François, duc de Choiseul. The first recorded sighting by Europeans was by the Spanish expedition of Álvaro de Mendaña in April 1568. More precisely the sighting was due to a local voyage done by a small boat, in the accounts the brigantine ''Santiago'', commanded by Maestre de Campo Pedro Ortega Valencia and having Hernán Gallego as pilot. They charted it as ''San Marcos'', and also named the narrow channel separating San Jorge from Santa Isabel Island as the Ortega channel after the commander of the expedition. In the nineteenth century Choiseul islanders suffered attacks from blackbirding (the often brutal recruitment or kidnapping o ...

Santa Isabel Island
Santa Isabel Island (also known as Isabel, Ysabel and Mahaga) is the longest in Solomon Islands, the third largest in terms of surface area, and the largest in the group of islands in Isabel Province. Location and geographic data Choiseul lies to the north-west, Malaita to the south-east. The Pacific Ocean lies to the north, and Guadalcanal (Isatabu) to the south. The highest point in Santa Isabel is Mount Sasari, . The Marutho river runs down Mount Sasari to the ocean at Hofi. Almost all the rivers or streams run from that centre point except for those at the other tip of the island on the Katova side. The administrative centre is Buala. The nearest airport is Fera Airport on neighbouring Fera Island. History The first European landing in the Solomon Islands archipelago was made at Santa Isabel Island, by the Spanish explorer Álvaro de Mendaña on 7 February 1568. It was charted as ''Santa Isabel de la Estrella'' (St. Elizabeth of the Star of Bethlehem in Spanish). A set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands (archipelago)
The Solomon Islands (archipelago) is an island group in the western South Pacific Ocean, north-east of Australia. The archipelago is in the Melanesian subregion and bioregion of Oceania and forms the eastern boundary of the Solomon Sea. The many islands of the archipelago are distributed across Papua New Guinea and Solomon Islands (country). The largest island in the archipelago is the Bougainville Island, which is a part of the Autonomous Region of Bougainville (currently a part of Papua New Guinea) along with Buka Island, the Nukumanu Islands, and a number of smaller nearby islands. Much of the remainder falls within the territory of Solomon Islands and include the atolls of Ontong Java, Sikaiana, the raised coral atolls of Bellona and Rennell, and the high islands of Choiseul, Guadalcanal, Makira, Malaita, New Georgia, the Nggelas, Santa Isabel, and the Shortlands. Geography The Solomon Islands (archipelago) consists of over 1,000 islands, ranging from low-lying cora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical Or Tropical Moist Lowland Forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Accipiter
''Accipiter'' is a genus of Bird of prey, birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species (excepting the northern goshawk) are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a coracoid, procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus ''Hieraspiza''.Olson (2006) Extant accipiters range in size from the little sparrowhawk (''A. minullus''), in which the smallest males measure long, span across the wings and weigh , to the northern goshawk (''A. gentilis''), in which the largest females measure long, span across the wings, and weigh . These birds are slender with short, broad, rounded wings and a long tail which helps them mane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
