Bird Fallout
Bird fallout or migration fallout is the result of severe weather preventing migratory birds from reaching their destination. This can occur while birds are traveling south or returning to their breeding grounds. Due to the distance travelled, birds will not have enough energy to continue flight when encountering high winds. This exhaustion results in many birds resting in one area. This may be very stressful on the birds and on the surrounding ecology. Bird fallout is not particularly common, as it stems from the chance event of severe winds found in inclement weather. Due to the rare occurrence of a migratory fallout, as well as the abundance of birds resting in a single location, it is a sought-after event for birders. Consequences There can be some significant consequences due to birds encountering severe weather during their migratory flyway. Late arrival to their destination can lead to a delay in reproduction, or a higher mortality rate. Due to the large number of bird ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wintering
Winter is the coldest season of the year in Polar regions of Earth, polar and temperate climates. It occurs after autumn and before spring (season), spring. The tilt of Axial tilt#Earth, Earth's axis causes seasons; winter occurs when a Hemispheres of Earth, hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with daytime, day length increasing and nighttime, night length decreasing as the season progresses after the solstice.

Birders
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 it in ...

Flyways
A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their overwintering quarters. Flyways generally span continents and often pass over oceans. Although applying to any species of migrating bird, the concept was first conceived and applied to waterfowl and shore birds. The flyways can be thought of as wide arterial highways to which the migratory routes of different species are tributaries. An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating. There are four major north–south flyways in North America and six covering Eurasia, Africa, and Australasia. History The passing of the Migratory Bird Treaty Act of 1918 in the United States resulted in a need for more information on bird migration. Frederick Charles Lincoln was put in charge and improved methods for trapping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Auk
''Ornithology'', formerly ''The Auk'' and ''The Auk: Ornithological Advances'', is a peer-reviewed scientific journal and the official publication of the American Ornithological Society (AOS). It was established in 1884 and is published quarterly. The journal covers the anatomy, behavior, and distribution of birds. It was named for the great auk, the symbol of the AOS. In 2018, the American Ornithology Society announced a partnership with Oxford University Press to publish ''The Auk: Ornithological Advances'' and '' The Condor: Ornithological Applications'' ''.'' In January 2021, the journal was renamed ''Ornithology'', with the stated goal of improving descriptiveness, thematic focus, and ease of citation of the journal title. The society's sister publication '' The Condor'' was renamed ''Ornithological Applications'' at the same time. Editors The following have been editors-in-chief of the journal: See also * List of ornithology journals References External links ...

EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the ÉPOQ database, created by Jacque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stressor
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.Deckers, Lambert (2018). Motivation Biological, Psychological, and Environmental. New York, NY: Routledge. pp. 208-212. . Events or objects that may trigger a stress response may include: * environmental stressors ( hypo or hyper-thermic temperatures, elevated sound levels, over-illumination, overcrowding) * daily "stress" events (e.g., traffic, lost keys, money, quality and quantity of physical activity) * life changes (e.g., divorce, bereavement) * workplace stressors (e.g., high job demand vs. low job control, repeated or sustained exertions, forceful exertions, extreme postures, office clutter) * chemical stressors (e.g., tobacco, alcohol, drugs) * social stressor (e.g., socie ...
