Ashy-breasted Flycatcher
The ashy-breasted flycatcher (''Muscicapa randi'') is a species of bird in the family Muscicapidae. It is endemic to the Philippines found only on the islands of Negros and Luzon. Its natural habitat is tropical moist lowland forests. It is threatened by habitat loss. Description EBird describes the bird as "A little-known small drab bird of lowland and foothill forest. Gray-brown above, darker in the wing, with a gray-brown chest blending to a white belly and a small white throat patch. Note the bicolored bill, black above and orange below. Similar to Furtive Flycatcher, but slightly larger, with an orange lower bill, no rufous outer tail feathers, and no black band on the end of the tail. Song consists of very high-pitched short phrases repeated at intervals. " Habitat and conservation status It inhabits primary and secondary growth forest up to 1,000 meters above sea level. It exhibits some tolerance to habitat degradation being recorded in clearings. It is often found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat Degradation
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, intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1970
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 swimming. Bi ...

Endemic Birds Of The Philippines
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in Birds. Patterns of endemism Under the most up-to-date taxonomy, there are 237 bird species endemic to the Philippines. Many of these are restricted to specific islands, particularly Luzon, Mindanao, and Palawan."A Guide to the Birds of the Philippines", Robert S. Kennedy et al., Oxford University Press, 2013. The number of endemic species recognized in the Philippines has increased in recent years, mainly due to 'splits' of species and, to a much lesser extent, due to the discovery of previously unknown species. An example of splitting is the division of the erstwhile species Philippine hawk-owl (''Ninox scutulata'') into seven different species, now called by the name of this-or-that Boobook (Luzon Boobook, Mindoro Boobook, etc...see the list below). Another example is the split of the erstwhile tarictric h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscicapa
''Muscicapa'' is a genus of passerine birds belonging to the Old World flycatcher family Muscicapidae, and therein to the typical flycatchers of subfamily Muscicapinae. They are widespread across Europe, Africa and Asia with most species occurring in forest and woodland habitats. Several species are migratory, moving south from Europe and northern Asia for the winter.Sinclair ''et al.'' (2003), Perrins (2004), del Hoyo ''et al.'' (2006) They are small birds, in length. They have a large head, short tail and a flattened bill, broader at the base. Their plumage is mostly drab brown or grey and rather plain. Young birds tend to be more spotted or mottled. ''Muscicapa'' flycatchers typically feed on flying insects which are caught by sallying out from an exposed perch. The nest is usually cup-shaped and built on a tree branch but some African species nest in tree holes. Taxonomy and systematics The genus was introduced by the French zoologist Mathurin Jacques Brisson i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Makiling
Mount Makiling (also known as Mount Maquiling), is an inactive stratovolcano located in the provinces of Laguna and Batangas on the island of Luzon, Philippines. The mountain rises to an elevation of above mean sea level and is the highest feature of the Laguna Volcanic Field. The volcano has no recorded historic eruption but volcanism is still evident through geothermal features like mud spring and hot springs. South of the mountain is the Makiling-Banahaw Geothermal Plant. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) classifies the volcano as "Inactive". Mount Makiling is a state-owned forest reserve administered by the University of the Philippines Los Baños. Prior to its transfer to the university, the mountain was the first national park of the Philippines. Mount Makiling National Park was established on February 23, 1933, by ''Proclamation No. 552''. However, it was decommissioned as a national park on June 20, 1963, by ''Republic Act no. 3523'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Agricultural Conversion
Land development is the alteration of landscape in any number of ways such as: * Changing landforms from a natural or semi-natural state for a purpose such as agriculture or House, housing * subdivision (land), Subdividing real estate into Lot (real estate), lots, typically for the purpose of building homes * Real estate development or changing its purpose, for example by converting an unused factory complex into a condominium. Economic aspects In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to investment making land more usable by humans. For accounting purposes it refers to any variety of projects that increase the property value, value of the process . Most are depreciable, but some land improvements are not able to be depreciated because a useful life cannot be determined. Home building and containment are two of the most common and the oldest types of development. In an Urban development, urban context ...

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...
