Grey-breasted Brown-Dove
The grey-breasted brown dove (''Phapitreron amethystinus maculipectus'') is a subspecies of amethyst brown dove in the family Columbidae. It is endemic to the Philippines being found in Negros and Panay. Its natural habitats are or tropical moist lowland forests and tropical moist montane forests. It is found in lowlands but probably prefers middle and high elevations at 500-2000m. It is most often seen singly or in pairs, in and around fruiting trees. The call is a deep, sonorous "hoot-hoot-hoot-hoot", and birds may sit and call for long periods. Description It is differentiated from the amethyst brown dove in Luzon (''amethystinus'' subspecies) and Mindanao (''imeldae'' subspecies) with is light grey breast and overall lighter appearance. It also has a longer bill and pink legs. The HBW and BirdLife International Illustrated Checklist of the Birds of the World considers it as a separate species ''Phapitreron maculipectus.'' Conservation status The dove is considered rare i ... [...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.

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 ...

Birds Described In 1894
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phapitreron
Brown doves are members of the genus ''Phapitreron'' in the pigeon family. Their common name refers to their overall brown coloration. They are endemic to the Philippines. All brown doves are tree-dwellers, but the different species occupy different types of wooded habitats; some are more restricted to old-growth forest while other make use of secondary forest and other woodland. Their main diet is fruit. They tend to be solitary in their habits and can be elusive. Some species in this genus have conspicuous black and white stripes on their faces and iridescent neck feathers. Males and females look alike. Taxonomy The genus ''Phapitreron'' was introduced in 1854 by the French naturalist Charles Lucien Bonaparte for the white-eared brown dove (''Phapitreron leucotis''). The genus name ''Phapitreron'' combines the genus name ''Phaps'' introduced by the English naturalist Prideaux John Selby in 1835 for the bronze-wing pigeons with the Ancient Greek ''trērōn'' meaning "pigeon".

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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).
