Lionel Walter Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

Phasianidae
The Phasianidae are a family (biology), family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, Turkey bird, turkeys, Old World quail, and peafowl. The family includes many of the most popular Game (hunting), gamebirds. The family is a large one and includes 185 species divided into 54 genera. It was formerly broken up into two subfamily (biology), subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyly, paraphyletic and polyphyly, polyphyletic, respectively, and more recent evidence supports breaking it up into two subfamilies: Rollulinae and Phasianinae, with the latter containing multiple Tribe (biology), tribes within two Clade, clades. The New World quail (Odontophoridae) and guineafowl (Numididae) were formerly sometimes included in this family, but are now typically placed in families of their own; conversely, grouse and turkey (bird), turkeys, formerly often treated as distinct families ...

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 ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Indonesia
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at . With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population. Indonesia is a presidential republic with an elected legislature. It has 38 provinces, of which nine have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, and India ...

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 ...

Grey-breasted Partridge
The grey-breasted partridge (''Arborophila orientalis''), also known as the white-faced hill partridge, or Horsfield's hill partridge, is a bird species in the family Phasianidae. It is endemic to highland forest in the eastern salient of Java, Indonesia. Sightings have been mostly reported from frequently visited nature preserves such as Kawah Ijen in Banyuwangi. Measuring , this species is a stocky, short-legged bird. Its mostly grey plumage is barred on the lower back and tail. It has a black crown and nape, and conspicuous white forehead, cheeks and throat. Bare skin around the eyes is red. The bill is black and the legs are red. Some authorities include the Malayan, Roll's and Sumatran partridges as subspecies of the grey-breasted partridge. The grey-breasted partridge is threatened by habitat loss.

Arborophila
''Arborophila'' is a bird genus in the family Phasianidae. The genus has the second most members within the Galliformes after ''Pternistis'', although ''Arborophila'' species vary very little in bodily proportions with different species varying only in colouration/patterning and overall size. These are fairly small, often brightly marked partridges found in forest of eastern and southern Asia. Some species in this genus have small ranges, and are threatened by habitat loss and hunting. Taxonomy The genus ''Arborophila'' was introduced in 1837 by the English naturalist Brian Houghton Hodgson to accommodate a single species, the hill partridge, which is therefore the type species. The genus name combines the Latin ''arbor'', ''arboris'' meaning "tree" with the Ancient Greek ''philos'' meaning "-loving". Species While most species in this genus are highly distinctive and their taxonomic Taxonomy is the practice and science of categorization or classification. A taxonomy (or ...

Birds Of Sumatra
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. Bird ...
