Ornithological Handbooks
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guild (ecology), guilds, island biogeography, phylogeography, and bird conservation, conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine. Foundations Cells Although there are differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falconry
Falconry is the hunting of wild animals in their natural state and habitat by means of a trained bird of prey. Small animals are hunted; squirrels and rabbits often fall prey to these birds. Two traditional terms are used to describe a person involved in falconry: a "falconer" flies a falcon; an "austringer" (Old French origin) flies a hawk (''Accipiter'', some buteos and similar) or an eagle ('' Aquila'' or similar). In modern falconry, the red-tailed hawk (''Buteo jamaicensis''), Harris's hawk (''Parabuteo unicinctus''), and the peregrine falcon (''Falco perigrinus'') are some of the more commonly used birds of prey. The practice of hunting with a conditioned falconry bird is also called "hawking" or "gamehawking", although the words hawking and hawker have become used so much to refer to petty traveling traders, that the terms "falconer" and "falconry" now apply to most use of trained birds of prey to catch game. Many contemporary practitioners still use these words in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poultry
Poultry () are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys). The term also includes birds that are killed for their meat, such as the young of pigeons (known as squabs) but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word ''poule'', itself derived from the Latin word ''pullus'', which means "small animal". Recent genomic study involving the four extant Junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia - although this was previously believed to have occurred later - around 5,400 years ago - in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnoornithology
Ethnoornithology (also ethno-ornithology) is the study of the relationship between people and birds (from " ethno-" - relating to people and culture - and "ornithology" - the study of birds). It is a branch of ethnozoology and so of the wider field of ethnobiology. Ethnoornithology is an interdisciplinary subject and combines anthropology, anthropological, cognitive and linguistic perspectives with natural scientific approaches to the description and interpretation of people's knowledge and use of birds. Like ethnoscience and other cognate terms, "ethnoornithology" is sometimes used narrowly to refer to people's practice rather than the study of that practice. The broader focus is on how birds are perceived, used and managed in human societies, including their use for food, medicine and personal adornment, as well as their use in divination and ritual. Applied ethnoornithological research is also starting to play an increasingly important role in the development of conservation init ...

Onomatopoeic
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as ''oink'', ''meow'' (or ''miaow''), ''roar'', and ''chirp''. Onomatopoeia can differ between languages: it conforms to some extent to the broader linguistic system; hence the sound of a clock may be expressed as ''tick tock'' in English, in Spanish and Italian (shown in the picture), in Mandarin, in Japanese, or in Hindi. The English term comes from the Ancient Greek compound ''onomatopoeia'', 'name-making', composed of ''onomato''- 'name' and -''poeia'' 'making'. Thus, words that imitate sounds can be said to be onomatopoeic or onomatopoetic. Uses In the case of a frog croaking, the spelling may vary because different frog species around the world make different sounds: Ancient Greek (only in Aristophanes' comic play ''The Frogs'') probably ...

Facsimile Painting Of Geese, Tomb Of Nefermaat And Itet MET DT226227
A facsimile (from Latin ''fac simile'', "to make alike") is a copy or reproduction of an old book, manuscript, map, art print, or other item of historical value that is as true to the original source as possible. It differs from other forms of reproduction by attempting to replicate the source as accurately as possible in scale, color, condition, and other material qualities. For books and manuscripts, this also entails a complete copy of all pages; hence, an incomplete copy is a "partial facsimile". Facsimiles are sometimes used by scholars to research a source that they do not have access to otherwise, and by museums and archives for media preservation and conservation. Many are sold commercially, often accompanied by a volume of commentary. They may be produced in limited editions, typically of 500–2,000 copies, and cost the equivalent of a few thousand United States dollars. The term "fax" is a shortened form of "facsimile" though most faxes are not reproductions of the quali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Oronsay, Inner Hebrides
Oronsay ( gd, Orasaigh), also sometimes spelt and pronounced ''Oransay'' by the local community, is a small tidal island south of Colonsay in the Scottish Inner Hebrides with an area of . The island rises to a height of at Beinn Orasaigh and is linked to Colonsay by a tidal causeway called ''An Tràigh'' (The Strand) consisting of sands and mud flats. In the 2001 census Oronsay was recorded as having a population of five people, who lived at the farm adjacent to Oronsay Priory. In 2011 the population had risen to eight. The island has no facilities for visitors and is now privately owned, with the RSPB farming the island for the American owner. It is dependent upon tidal access to and from Colonsay. There is a small grass air strip south of the priory that "fights a losing battle with the rabbits". Etymology There are two theories for the origin of the name from Old Norse. Either it is ''Oran's Isle'', St Oran being imagined as the founder of the island's original monastery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shell Mound
A midden (also kitchen midden or shell heap) is an old dump for domestic waste which may consist of animal bone, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell mid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
