Visayan Bulbul
The Visayan bulbul (''Hypsipetes guimarasensis'') or Steere's bulbul, is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the western Visayas in the Philippines. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Until 2010, it was considered to be a subspecies of the Philippine bulbul. Taxonomy and description The Visayan bulbul was originally described in the genus '' Iole'' and has also been classified by some authorities as a separate species in the genus ''Ixos''. Until 2010, it was considered to be a subspecies of the Philippine bulbul but others still maintain that this is just a sub-species. EBird describes the bird as "A medium-sized bird of lowland and montane forest and more open wooded areas in the west-central Philippines. Dark brown above with a grayish-brown streaked crown, a white belly, white under the base of the tail, and a warm reddish-brown throat and chest. So ...

Joseph Beal Steere
Joseph Beal Steere (9 February 1842 – 7 December 1940) was an American ornithologist. Steere was born in Rollin, Michigan, the son of William Millhouse and Elizabeth Cleghorn (Beal) Steere. He received a B.A. from the University of Michigan in 1868 and a B. of Law in 1870. Shortly after his graduation he entered upon an extensive tour to make collections for the University Museum. His mother's cousin, Rice A. Beal—owner and publisher of the ''Ann Arbor Courier''—agreed to pay for the expedition if Steere would write letters from his journey to be published in the ''Courier''. He spent about eighteen months on the Amazon River and its tributaries, making collections in zoology, botany and archaeology. He crossed the Andes and continued his collections in various parts of Peru. He then sailed for China and the island of Formosa (Taiwan). He went on another scientific expedition in 1887 to the Philippines where he made an extensive collection of birds, shells, and other natu ...

EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the ÉPOQ database, created by Jacque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Visayas
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''. 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". 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'' comes from the name 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, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hypsipetes
__NOTOC__ ''Hypsipetes'' is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland. Most ''Hypsipetes'' bulbuls are dark greyish birds with orange or red bills and feet. The feathers on top of the head are slightly elongated and usually black, and can be erected to form a short and wispy crest. Taxonomy and systematics The genus ''Hypsipetes'' was introduced in 1831 by the Irish zoologist Nicholas Aylward Vigors with ''Hypsipetes psaroides'' as the type species. This taxon is now a subspecies of the black bulbul ''Hypsipetes leucocephalus psaroides''. The genus name combines the Ancient Greek ''hupsi'' meaning "high" with ''petēs'' meaning "-flyer". Species The genus contains 19 species: * Philippine bulbul (''Hypsipetes philippinus'') * Mindoro bulbul (''Hypsipetes mind ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...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] |
Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Old-growth 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] |
White-vented Whistler
The white-vented whistler (''Pachycephala homeyeri'') is a species of bird in the family Pachycephalidae. It is found in the southern Philippines and a few islands of Malaysia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Taxonomy and systematics The alternate name 'white-bellied whistler' should not be confused with the species of the same name, '' Pachycephala leucogastra''. Formerly, some authorities considered the white-vented whistler to be a subspecies of the mangrove whistler. Subspecies Three subspecies are recognized: * ''P. h. homeyeri'' – ( Blasius, W., 1890): Found in south and southwestern Philippines; Sipadan and Pandanan Islands, off eastern Sabah (Malaysia) * ''P. h. major'' – ( Bourns & Worcester, 1894): Found on Cebu Cebu (; ceb, Sugbo), officially the Province of Cebu ( ceb, Lalawigan sa Sugbo; tl, Lalawigan ng Cebu; hil, Kapuroan sang Sugbo), is a province of the Philippine ...

Negros Jungle-flycatcher
The white-throated jungle flycatcher (''Vauriella albigularis''), also known as the Negros jungle flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It is endemic to the Philippines (Negros and Panay islands) and formerly on Guimaras before its extirpation there. The natural habitats of the white-throated jungle flycatcher are tropical moist lowland forests and tropical moist montane forests up to 1,350 masl. It is threatened by habitat loss. This species was previously placed in the genus ''Rhinomyias'' but was moved to ''Vauriella'' after a detailed molecular phylogenetic study published in 2010 found that ''Rhinomyias'' was polyphyletic. Description EBird describes the bird as "A fairly small bird. Rufous-brown on the wings, back, and tail, with a gray head, heavily-streaked pale underparts, and a black face and moustache stripe. Often found in mixed-species flocks. Somewhat similar to Stripe-headed rhabdornis and Grand rhabdornis, but sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
