Christmas Bird Count
The Christmas Bird Count (CBC) is a census of birds in the Western Hemisphere, performed annually in the early Northern-hemisphere winter by volunteer birdwatchers and administered by the National Audubon Society. The purpose is to provide population data for use in science, especially conservation biology, though many people participate for recreation. The CBC is the longest-running citizen science survey in the world. History Up through the 19th century, many North Americans participated in the tradition of Christmas "side hunts", in which they competed at how many birds they could kill, regardless of whether they had any use for the carcasses and of whether the birds were beneficial, beautiful, or rare. In December 1900, the U.S. ornithologist Frank Chapman, founder of Bird-Lore (which became Audubon magazine), proposed counting birds on Christmas instead of killing them. On Christmas Day of that year, 27 observers took part in the first count in 25 places in the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 swimming. B ...

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] |
Tucson Bird Count
The Tucson Bird Count (TBC) is a community-based program that monitors bird populations in and around the Tucson, Arizona, United States metropolitan area. With nearly 1000 sites monitored annually, the Tucson Bird Count is among the largest urban biological monitoring programs in the world. Methods Each spring, TBC participants collect data on bird abundance and distribution at hundreds of point count locations arrayed across the Tucson basin. The TBC is an example of citizen science, drawing on the combined efforts of hundreds of volunteers. So that data are of suitable quality for scientific analysis and decisionmaking, all TBC volunteers are skilled birdwatchers; many are also professional field guides or biologists. TBC methods are similar to those employed by the North American Breeding Bird Survey, although the TBC uses more closely spaced sites (one site per 1-km2 square) over a smaller total area (approximately 1000 km2). For full details of TBC methods, see the TBC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Backyard Bird Count
The Great Backyard Bird Count (GBBC) is a community science project in ornithology. It is conducted annually in mid-February. The event is supported by the Cornell Lab of Ornithology and the National Audubon Society The National Audubon Society (Audubon; ) is an American non-profit environmental organization dedicated to conservation of birds and their habitats. Located in the United States and incorporated in 1905, Audubon is one of the oldest of such organ .... During this four-day event, birdwatchers around the world are invited to count and report details of birds in the area in which they live. Data is submitted online via a web interface, and compiled for use in scientific research. The GBBC was the first community science project to collect bird sightings online and display results in near real-time. Overview The GBBC was first launched in 1998 in the US. It is conducted around the second week of February. Since 2013, the event has been observed by international bird watch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BioBlitz
A BioBlitz, also written without capitals as bioblitz, is an intense period of biological surveying in an attempt to record all the living species within a designated area. Groups of scientists, naturalists and volunteers conduct an intensive field study over a continuous time period (e.g., usually 24 hours). There is a public component to many BioBlitzes, with the goal of getting the public interested in biodiversity. To encourage more public participation, these BioBlitzes are often held in urban parks or nature reserves close to cities. Research into the best practices for a successful BioBlitz has found that collaboration with local natural history museums can improve public participation. As well, BioBlitzes have been shown to be a successful tool in teaching post-secondary students about biodiversity. Features A BioBlitz has different opportunities and benefits than a traditional, scientific field study. Some of these potential benefits include: *Enjoyment – Instead of a ...

Australian Bird Count
The Australian Bird Count (ABC) was a project of the Royal Australasian Ornithologists Union (RAOU). Following the first and successful Atlas of Australian Birds project, which led to the publication of a book on the distribution of Australian birds in 1984, it was suggested by Ken Rogers (ornithologist), Ken Rogers that the RAOU should next look at bird migration and other movements in Australia. Methodology for a suitable project involving volunteers was worked out through experimental fieldwork and a workshop on ‘Monitoring the Populations and Movements of Australian Birds’. A project manager, [Stephen Ambrose], was appointed and project fieldwork ran from January 1989 to August 1995. Some 950 volunteer observers carried out 79,000 surveys, for fixed 20-minute periods in 1700 three-hectare locations over Australia. Project management started at the Australian Museum in Sydney and was later moved to the RAOU National Office in Melbourne. Financial support came at first fro ...

Palacios, Texas
Palacios ( ) is a city in Matagorda County, Texas, United States. The population was 4,395 at the 2020 census. Etymology Popular local legend states that the area was named Tres Palacios ("Three Palaces") several centuries ago by shipwrecked Spanish sailors who claimed they saw a vision of three palaces on the bay. Historians believe it was more likely named for José Félix Trespalacios, an early Mexican governor of Texas. The town was originally called Trespalacios, but shortened its name due to a nearby post office already using the longer version. History The native inhabitants of the region were the Karankawa people, whose initial contact with Europeans came in the 16th century when Spanish expeditions first traversed their territory. In 1685, the area was explored by René-Robert Cavelier, Sieur de La Salle, the leader of an ill-fated French settlement attempt whose flagship '' La Belle'' was wrecked in the bay the following year. In the 1820s, English-speaking settlers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
