Streak-breasted Bulbul
The streak-breasted bulbul (''Hypsipetes siquijorensis'') is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Philippines being found in the Visayas on the islands of Tablas Island, Siquijor, Cebu and Romblon where its natural habitat is tropical moist lowland forest and tropical moist shrubland. It is threatened by habitat loss and hunting. Description and taxonomy EBird describes the bird as "A medium-sized bird of foothill forest and edge as well as more open wooded areas. Fairly large for a bulbul. Dark brown above with a pale belly and a warm brown chest and throat with pale streaking. Note brown cheek and black crown that can be raised into a spiky crest. Similar to Philippine Bulbul, but larger, with a longer bill, a black crown, and a paler throat and chest. Voice consists of rather unpleasant grating chatters and harsh downslurred squeals." However, this description mostly refers to the ''siquijorensis'' sub-species (potentially a split) ...

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 ...

Forest Restoration
Forest restoration is defined as “actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest” i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible ''within the limits imposed by climate and soil and without continued disturbance from humans'' (more explanation here). Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Forest restoration is a specialized form of reforestation, but it differs from conventional tree plantations in that its primary goals are biodiversity recovery and environmental protection. Forest and landscape re ...

Philippine Bulbul
The Philippine bulbul (''Hypsipetes philippinus'') is a songbird species in the bulbul family, Pycnonotidae. It is endemic to the Philippines. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest; on Mount Kitanglad on Mindanao, for example, it is abundant in any kind of primary forest at least between 500 and 2,250 m ASL. Taxonomy and systematics The Philippine bulbul was originally described in the genus ''Turdus'' and later placed in the genus ''Ixos''. In 2010, it was re-classified to the genus ''Hypsipetes'' as it is very closely related to the type species of that genus, the black bulbul. Until 2010, the Mindoro bulbul, Visayan bulbul and Zamboanga bulbul were all considered as subspecies of the Philippine bulbul. Subspecies Three subspecies are currently recognized: * ''H. p. parkesi'' - du Pont, 1980: Found on Burias * ''H. p. philippinus'' - ( Forster, 1795): Found in northern Philippines * ''H. p. ...

Yellow-vented Bulbul
The yellow-vented bulbul (''Pycnonotus goiavier''), or eastern yellow-vented bulbul, is a member of the bulbul family of passerine birds. It is a resident breeder in southeastern Asia from Indochina to the Philippines. It is found in a wide variety of open habitats but not the deep forest. It is one of the most common birds in cultivated areas. They appear to be nomadic and roam from place to place regularly. Taxonomy and systematics The yellow-vented bulbul was originally classified in the genus ''Muscicapa''. Subspecies Six subspecies are recognized: * ''P. g. jambu'' - Herbert Girton Deignan, Deignan, 1955: Found from southern Myanmar to southern Indochina * ''P. g. analis'' - (Thomas Horsfield, Horsfield, 1821): Originally described as a separate species in the genus ''Turdus''. Found on Malay Peninsula, Sumatra and nearby islands, Java, Bali, Lombok and Sumbawa * ''P. g. gourdini'' - George Robert Gray, Gray, GR, 1847: Originally described as a separate species in the genus ...

Interspecies Competition
Interspecific competition, in ecology, is a form of competition in which individuals of ''different'' species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis. Competition between members of the same species is called intraspecific competition. If a tree species in a dense forest grows taller than surrounding tree species, it is able to absorb more of the incoming sunlight. However, less sunlight is then available for the trees that are shaded by the taller tree, thus interspecific competition. Leopards and lions can also be in interspecific competition, since both species feed on the same prey, and can be negatively impacted by the presence of the other because they will have less food. Competition is only one of many interacting biotic and abiotic factors that affect community structure. Moreover, competition is not always a straightforward, direct, interaction. Interspecific competition may ...

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 ...

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. Description Depending on the forest, the development of ...

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 ...

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).
