Grosbeak Bunting
Wilkins's Bunting (''Nesospiza wilkinsi''), also known as the grosbeak bunting, is a species of bird in the family Thraupidae. It is restricted to Inaccessible Island (subspecies ''dunnei'') and Nightingale Island (nominate ''wilkinsi'') of the Tristan da Cunha archipelago, part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha in the South Atlantic Ocean. Its natural habitats are temperate shrubland and subantarctic grassland. The common name and Latin binomial commemorate the Australian polar explorer and ornithologist Captain Sir George Hubert Wilkins.

Percy Lowe
Percy Roycroft Lowe (2 January 1870 – 18 August 1948) was an English surgeon and ornithologist. Life Lowe was born at Stamford, Lincolnshire and studied medicine at Jesus College, Cambridge. He served as a civil surgeon in the Second Boer War, and it was whilst in South Africa that he became interested in ornithology. On his return he became private physician to Sir Frederick Johnstone, 8th Baronet, whose constant travel exposed Lowe to birds all around the world. During World War One he served in the Royal Army Medical Corps; he was Officer in Command on Princess Christian Ambulance Train for which he was awarded the OBE in 1920. Lowe worked with Dorothea Bate on fossil ostriches in China. In November 1919 he succeeded William Robert Ogilvie-Grant as Curator of Birds at the Natural History Museum, retiring on his sixty-fifth birthday in 1935. He was succeeded by Norman Boyd Kinnear. He was editor of the Bulletin of the British Ornithologists' Club from 1920 to 1925 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Percy Lowe
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1923
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furth ...

Nesospiza
''Nesospiza'' is a genus of seed-eating birds in the tanager family Thraupidae found on the Tristan da Cunha archipelago in the South Atlantic Ocean. Taxonomy and species list The genus ''Nesospiza'' was introduced in 1873 by the German ornithologist Jean Cabanis with the Inaccessible Island finch as the type species. The genus name combines the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... ''nēsos'' meaning "island" (i.e. Tristan da Cunha) with ''spiza'' meaning "finch".

George Hubert Wilkins
Sir George Hubert Wilkins MC & Bar (31 October 188830 November 1958), commonly referred to as Captain Wilkins, was an Australian polar explorer, ornithologist, pilot, soldier, geographer and photographer. He was awarded the Military Cross after he assumed command of a group of American soldiers who had lost their officers during the Battle of the Hindenburg Line, and became the only official Australian photographer from any war to receive a combat medal. He narrowly failed in an attempt to be the first to cross under the North Pole in a submarine, but was able to prove that submarines were capable of operating beneath the polar ice cap, thereby paving the way for future successful missions. The US Navy later took his ashes to the North Pole aboard the submarine USS ''Skate'' on 17 March 1959. Early life Hubert Wilkins was a native of Mount Bryan East, South Australia, the last of 13 children in a family of pioneer settlers and sheep farmers. He was born at Mount Bryan East, ...

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

British Overseas Territories
The British Overseas Territories (BOTs) or alternatively referred to as the United Kingdom Overseas Territories (UKOTs) are the fourteen dependent territory, territories with a constitutional and historical link with the United Kingdom that, while not forming part of the United Kingdom itself, are part of its sovereign territory. The permanently inhabited territories are delegated varying degrees of internal self-governance, with the United Kingdom retaining responsibility for Military, defence, foreign relations, and internal security, and ultimate responsibility for governance. Three of the territories are chiefly or only inhabited by military or scientific personnel, the rest hosting significant civilian populations. All fourteen have the British monarch as head of state. These UK government responsibilities are assigned to various departments of the Foreign, Commonwealth and Development Office and are subject to change.
