Kivu Ground Thrush
The Kivu ground thrush (''Geokichla piaggiae tanganicae'') is a bird subspecies native to the Albertine Rift montane forests. Its natural habitat is subtropical or tropical moist montane forests. 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 .... It is currently considered a subspecies of the Abyssinian ground thrush.

Moritz Sassi
Moriz Sassi or Moritz Sassi (13 June 1880 – 25 September 1967) was an Austrian ornithologist who worked at the Natural History Museum in Vienna. In 1933 he was made a government councilor and given the title of ''hofrat''. Sassi was born in Vienna to Eugen and Ida who owned the Schwindgasse palace in Vienna and Villa Sassi in nort. Sassi went to school at Hegelgasse and volunteered with the Dragoons. He then studied zoology at the University of Vienna under Karl Grobben and Berthold Hatschek writing a dissertation on the anatomy of ''Anomia ephippium'' for which he received a doctorate in 1903. He then followed an interest in art. In 1905 he joined an expedition into Anglo-Egyptian Sudan led by Franz Werner and collected numerous specimens of birds and mammals, and describing several as new to science including ''Procavia slatini'' (now merely a synonym for the rock hyrax) dedicated to his friend Rudolf Slatin. In 1908 he joined the Natural History Museum in Vienna under Franz Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertine Rift Montane Forests
The Albertine Rift montane forests is a tropical moist broadleaf forest ecoregion in east-central Africa. The ecoregion covers the mountains of the northern Albertine Rift, and is home to distinct Afromontane forests with high biodiversity. Geography The high montane forests cover the western portions of Rwanda and Burundi, the eastern edge of the Democratic Republic of the Congo, and portions of western Uganda and Tanzania. This area occupies the parallel Albertine Rift Mountains that enclose the western branch of the East African Rift. The mountain ranges include the Lendu Plateau of Uganda (the forest is almost completely cleared from here), and the Virunga Mountains and Rwenzori Mountains of Rwanda, Uganda, and the Democratic Republic of the Congo. At the highest elevations of the Rwenzori and Virunga ranges (above 3000 meters), the forests transition to the Afroalpine Rwenzori–Virunga montane moorlands ecoregion, including the high peaks of Mount Stanley and Mou ...

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] |
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 ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssinian Ground Thrush
The Abyssinian ground thrush (''Geokichla piaggiae'') is a thrush from the family Turdidae which is native to north-east Africa where it lives at high altitude in montane forests. Description The Abyssinian ground thrush is an attractive but rather secretive species. The adults are a deep rufous orange on the head and face with a distinct white eye ring, the orange colour becomes les rufous on the breast and flanks and the upperparts are olive brown except for the orange-brown rump and tail. On the folded wing it shows two prominent white wingbars from the tips to the coverts. Immature birds tend to be paler and duller than the adults. They measure in length and weigh . Voice The contact call of the Abyssinian ground thrush is a high pitched "tseep", the song is a typical thrush like melodious series of whistled phrases rendered in Sinclair & Ryan as "chee-cheeleeroo-chruup". Distribution and subspecies There are six currently recognised subspecies of Abyssinian ground thrush ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geokichla
The ''Geokichla'' thrushes are medium-sized mostly insectivorous or omnivorous birds in the thrush family, Turdidae. They were traditionally listed in the '' Zoothera'', but studies suggested their placement in another genus. The genus name ''Geokichla'' comes from Ancient Greek ''geo-'', "ground-" and ''kikhle'', " thrush". List of species * Siberian thrush, ''Geokichla sibirica'' * Pied thrush, ''Geokichla wardii'' *Grey ground thrush, ''Geokichla princei'' *Black-eared ground thrush, ''Geokichla cameronensis'' * Spotted ground thrush, ''Geokichla guttata'' - formerly ''G. fischeri'' * Spot-winged thrush, ''Geokichla spiloptera'' *Crossley's ground thrush, ''Geokichla crossleyi'' * Abyssinian ground thrush, ''Geokichla piaggiae'' ** Kivu ground thrush, ''Geokichla piaggiae tanganjicae'' *Oberländer's ground thrush, ''Geokichla oberlaenderi'' * Orange ground thrush, ''Geokichla gurneyi'' *Orange-headed thrush, ''Geokichla citrina'' *Buru thrush, ''Geokichla dumasi'' * Ser ...
