Tablas Drongo
The Tablas drongo (''Dicrurus menagei'') is an Asian bird of the family Dicruridae. It was formerly considered conspecific with the hair-crested drongo. It is endemic to Tablas Island in the Philippines. It is noted by its jet black plumage with a long fish-like tail. It inhabits tropical old-growth forest. Prior to 1998, it was not seen for many decades due to lack of surveys on the island. It is estimated to consist of just 50 to 250 mature adults making it one of the most endangered birds in the Philippines. It is threatened by habitat loss. Description and Taxonomy EBird describes the bird as "A medium-sized, long-tailed bird of forest canopy on Tablas, where it is the only drongo in range. Entirely black with glossy-blue wings, crown, and streaks on the neck and chest. Similar to Philippine Drongo-Cuckoo but larger, with a thicker bill and a strongly forked tail with upturned tips. Not as vocal as other drongos. Voice includes a grating scold followed by a loud, high-pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Swift Bourns
Frank Swift Bourns (1866 – 1935) was an American ornithologist and doctor. He was involved in two different expeditions to the Philippines with Dean Conant Worcester to gather natural history specimens. From 1887 to 1888 they participated in an expedition sponsored by Joseph Beal Steere. From 1890 to 1892 they returned on an expedition sponsored by Louis F. Menage and the Minnesota Academy of Natural Sciences. The two expeditions yielded thousands of specimens of birds and mammals including newly discovered species such as the Bornean slow loris and Sulu bleeding-heart. After the second expedition Bourns moved to Ann Arbor, Michigan Ann Arbor is a city in the U.S. state of Michigan and the county seat of Washtenaw County, Michigan, Washtenaw County. The 2020 United States census, 2020 census recorded its population to be 123,851. It is the principal city of the Ann Arbor ... where he completed his medical degree and became a doctor.

Primary Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Romblon
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna of Madagascar, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Greek language, Greek equivalent of fauna. ''Fauna'' is also ...

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] |
Drongos
The drongos are a family, Dicruridae, of passerine birds of the Old World tropics. The 30 species in the family are placed in a single genus, ''Dicrurus''. Drongos are mostly black or dark grey, short-legged birds, with an upright stance when perched. They have forked tails and some have elaborate tail decorations. They feed on insects and small birds, which they catch in flight or on the ground. Some species are accomplished mimics and have a variety of alarm calls, to which other birds and animals often respond. They are known to utter hoax alarm calls that scare other animals off food, which the drongo then claims. Taxonomy The genus ''Dicrurus'' was introduced by French ornithologist Louis Pierre Vieillot for the drongos in 1816. The type species was subsequently designated as the balicassiao (''Dicrurus balicassius'') by English zoologist George Robert Gray in 1841. The name of the genus combines the Ancient Greek words ''dikros'' "forked" and ''oura'' "tail". "Drongo" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slash-and-burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom. Slash-and-burn is a type of shif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Endangered Species (IUCN Status)
Endangered species as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process. A species can be "Near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dean Conant Worcester
Dean Conant Worcester, D.Sc., FRGS (October 1, 1866 – May 2, 1924) was an American zoologist, public official, and authority on the Philippines. He was born at Thetford, Vermont, and educated at the University of Michigan (A.B., 1889). He first went to the Philippines in 1887 as a junior member of a scientific expedition, and built a controversial career in the early American colonial government beginning in 1899 based upon his experience in the country. He was fiercely opposed to Philippine independence and a firm believer in the colonial mission. He served as the influential Secretary of the Interior of the Philippine Islands until 1913 when he began focusing on his business interests. He died in the Philippines having organized and managed businesses that included coconut farming and processing, cattle raising and a maritime shipping line.Sullivan, Rodney J. (1991).
