Birdwatching
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device like binoculars or a telescope, by listening for bird sounds, or by watching public webcams. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1901 by Edmund Selous; ''bird'' was introduced as a verb in 1918. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's ''The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because ...

Binoculars
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes ( binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models. Unlike a ( monocular) telescope, binoculars give users a three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an impression of depth. Optical designs Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean optics; that is, they used a convex objective and a concave eyepiece lens. The Galilean design has the advantage of presenting an erect image but has a narr ...

Wildlife Observation
Wildlife observation is the practice of noting the occurrence or abundance of animal species at a specific location and time, either for research purposes or recreation. Common examples of this type of activity are bird watching and whale watching. The process of scientific wildlife observation includes the reporting of what (diagnosis of the species), where ( geographical location), when (date and time), who (details about observer), and why (reason for observation, or explanations for occurrence). Wildlife observation can be performed if the animals are alive, with the most notable example being face-to-face observation and live cameras, or are dead, with the primary example being the notifying of where roadkill has occurred. This outlines the basic information needed to collect data for a wildlife observation; which can also contribute to scientific investigations of distribution, habitat relations, trends, and movement of wildlife species. Wildlife observation allows for the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Birding Association
The American Birding Association (ABA) is a nonprofit organization, founded in 1969, dedicated to recreational birding in Canada and the United States. It has been called "the standard-bearer for serious birding in North America." Originally concentrated on finding, listing, and identifying rare birds, the ABA now seeks to serve all birders with a wide range of services and publications. History In December 1968, in the first issue (volume 0, number 0) of ''The Birdwatcher's Digest'', Jim Tucker proposed the formation of a group to be known as the "American Birdwatchers' Association" for the exchange of information and the comparison of birding lists. On the suggestion of Stuart Keith, the next issue of Tucker's newsletter bore the name ''Birding'' (volume 1, number 1). This January/February 1969 issue included a statement of intentions and objectives and three pages of lists, including the birders with the top ten lists for the world and for the area then covered by the che ...

Bird
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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citizen Science
Citizen science (CS) (similar to community science, crowd science, crowd-sourced science, civic science, participatory monitoring, or volunteer monitoring) is scientific research conducted with participation from the public (who are sometimes referred to as amateur/nonprofessional scientists). There are variations in the exact definition of citizen science, with different individuals and organizations having their own specific interpretations of what citizen science encompasses. Citizen science is used in a wide range of areas of study, with most citizen science research publications being in the fields of biology and conservation. There are different applications and functions of citizen science in research projects. Citizen science can be used as a methodology where public volunteers help in collecting and classifying data, improving the scientific community's capacity. Citizen science can also involve more direct involvement from the public, with communities initiating proj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithology
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, guilds, island biogeography, phylogeography, and 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, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NMAAHC Bird Walk
The National Museum of African American History and Culture (NMAAHC) is a Smithsonian Institution museum located on the National Mall in Washington, D.C., in the United States. It was established in December 2003 and opened its permanent home in September 2016 with a ceremony led by President Barack Obama. Early efforts to establish a federally owned museum featuring African-American history and culture can be traced to 1915, although the modern push for such an organization did not begin until the 1970s. After years of little success, a much more serious legislative push began in 1988 that led to authorization of the museum in 2003. A site was selected in 2006, and a design submitted by Freelon Group/Adjaye Associates/Davis Brody Bond was chosen in 2009. Construction began in 2012 and the museum completed in 2016. The NMAAHC is the world's largest museum dedicated to African-American history and culture. It ranked as the fourth most-visited Smithsonian museum in its first full ...

Golden-winged Warbler
The golden-winged warbler (''Vermivora chrysoptera'') is a New World warbler. It breeds in southeastern and south-central Canada and in the Appalachian Mountains in northeastern to north-central United States. The majority (~70%) of the global population breeds in Wisconsin, Minnesota, and Manitoba. Golden-winged warbler populations are slowly expanding northwards, but are generally declining across its range, most likely as a result of habitat loss and competition/interbreeding with the very closely related blue-winged warbler, ''Vermivora cyanoptera''. Populations are now restricted to two regions: the Great Lakes and the Appalachian Mountains. The Appalachian population has declined 98% since the 1960s and is significantly imperiled. The U.S. Fish and Wildlife Service has been petitioned to list the species under the Endangered Species Act of 1973 and is currently reviewing all information after issuing a positive finding. Upon review, the U.S. Fish and Wildlife Service found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twitchers' Vocabulary
Twitchers' vocabulary is the set of jargon words used by twitchers (committed birdwatchers who travel long distances to see a new species to add a species to their "life list", year list or other list). Some terms may be specific to regional birding communities, and not all are used due to dialectic and cultural differences.Anon. 2008. "The A to Z of birding."

Thomas Bewick
Thomas Bewick (c. 11 August 17538 November 1828) was an English wood-engraver and natural history author. Early in his career he took on all kinds of work such as engraving cutlery, making the wood blocks for advertisements, and illustrating children's books. He gradually turned to illustrating, writing and publishing his own books, gaining an adult audience for the fine illustrations in ''A History of Quadrupeds''. His career began when he was apprenticed to engraver Ralph Beilby in Newcastle upon Tyne. He became a partner in the business and eventually took it over. Apprentices whom Bewick trained include John Anderson, Luke Clennell, and William Harvey, who in their turn became well known as painters and engravers. Bewick is best known for his '' A History of British Birds'', which is admired today mainly for its wood engravings, especially the small, sharply observed, and often humorous vignettes known as tail-pieces. The book was the forerunner of all modern field guides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
