Blue-headed Pitta
The blue-headed pitta (''Hydrornis baudii'') is a species of bird in the pitta family Pittidae. It is endemic to Borneo. Description The blue-headed pitta is a medium-sized pitta, at in length. The plumage of the male is very brightly coloured, with a bright blue crown, black cheeks, white throat, chestnut red back, violet blue tail and belly, and black wings marked with white. The colours of the female are more subdued, with a buff coloured back and head and blue only being found on the tail. Breeding The blue-headed pitta is believed to be a seasonal breeder, as birds in breeding condition have been found in the middle of the year (March to June) and a female that was about to lay was found in July. Young birds were also found in nests between May and October. The nest is typical of the family, a round dome of leaves with a side entrance near or on the ground. In the one nest examined two eggs were found. Distribution and habitat The species is endemic to the island of Born ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salomon Müller
Salomon Müller (7 April 1804 – 29 December 1864) was a German naturalist. He was born in Heidelberg, and died in Freiburg im Breisgau. Müller was the son of a saddler in Heidelberg.

Endemic Birds Of Borneo
The island of Borneo, located in southeast Asia at the southern edge of the South China Sea, is home to one endemic bird family, three endemic bird genera and 59 endemic bird species. All but one of the latter are forest dwellers, with most restricted to the spine of hills and mountains running down the middle of the island. The avian endemism has been shaped by the island's geological history. Borneo sits on a continental shelf. During glacial periods, when water levels were lower, Borneo was linked with other islands on the shelf and with the Malay peninsula in a large landmass known as Sundaland. This allowed bird species to move freely throughout the region until the waters rose again as the glaciers melted. Separated from their relatives by the sea, some of these species evolved over millennia into the endemics now found on the island. BirdLife International has designated the mountainous central spine of the island as an Endemic Bird Area (EBA) because of the number of endem ...

Hydrornis
''Hydrornis'' is a genus of pitta in the family Pittidae. The genus contains thirteen species, found in South-east Asia. The genus was formerly merged with the genus ''Pitta'', but a 2006 study split the family into three genera. Taxonomy The pittas were at one time all usually placed in the genus ''Pitta'', the only genus in the family Pittidae, but when a 2006 molecular phylogenetic study found that the pittas formed three separate groups, the genus was split and some species were moved into two resurrected genera, ''Erythropitta'' and ''Hydrornis''. The genus ''Hydrornis'' had been introduced by the English zoologist Edward Blyth in 1843 with the blue-naped pitta (''Hydrornis nipalensis'') as the type species. The name ''Hydrornis'' combines the Ancient Greek words "water" and "bird". The pittas in ''Hydrornis'' have sexually dimorphic Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological chara ...

Deforestation In Indonesia
Deforestation in Indonesia involves the long-term loss of forests and foliage across much of the country; it has had massive environmental and social impacts. Indonesia is home to some of the most biologically diverse forests in the world and ranks third in number of species behind Brazil and the Democratic Republic of Congo.ABC Four Corners: ''Background information on Indonesia, deforestation and illegal logging'' , Retrieved 28 May 2010 As late as 1900, Indonesia was still a densely forested country: forests represented 84 percent of the total land area. Deforestation intensified in the 1970s and has accelerated further since then. The estimated |
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 ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

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] |

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
