Non-migratory
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Animal Migration
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability of food, the season of the year or for mating. To be counted as a true migration, and not just a local dispersal or irruption, the movement of the animals should be an annual or seasonal occurrence, or a major habitat change as part of their life. An annual event could include Northern Hemisphere birds migrating south for the winter, or wildebeest migrating annually for seasonal grazing. A major habitat change could include young Atlantic salmon or sea lamprey leaving the river of their birth when they have reached a few inches in size. Some traditional forms of human migration fit this pattern. Migrations can be studied using tradition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altitudinal Migration
Altitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. Altitudinal migrants change their elevation with the seasons making this form of animal migration seasonal. Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. This behavior is commonly seen among avian species but can also be observed within other vertebrates and some invertebrates. It is commonly thought to happen in response to climate and food availability changes as well as increasingly due to anthropogenic influence. These migrations can occur both during reproductive and non-reproductive seasons. The patterns of altitudinal migration may be affected by climate change resulting in potentially life-threatening situations for some species. Deforestation can affect the migration corridors of altitudinal migrant and could lead to smaller areas for these species to migrate. Changes in the environment of altitudinally ...

Nile
The Nile (also known as the Nile River or River Nile) is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa. It has historically been considered the List of river systems by length, longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer.Amazon Longer Than Nile River, Scientists Say Of the world's major rivers, the Nile has one of the lowest average annual flow rates. About long, its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. In pa ...

White Stork
The white stork (''Ciconia ciconia'') is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average from beak tip to end of tail, with a wingspan. The two subspecies, which differ slightly in size, breed in Europe north to Finland, northwestern Africa, Palearctic east to southern Kazakhstan and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water. A carnivore, the white stork eats a wide range of animal prey, including insects, fish, amphibians, reptiles, small mammals and small birds. It take ...

Johann Natterer
Johann Natterer (9 November 1787 – 17 June 1843) was an Austrian natural history, naturalist and List of explorers, explorer. He was the son of royal falconer Joseph Natterer and along with his brother Joseph Natterer (1786–1852) took a keen interest in natural history. He collected natural history specimens extensively from South America and numerous species from his collections were named after him. Family and early life Johann Natterer was born in Laxenburg, Laxenberg, the son of the natural history specimen collector and falconer Joseph Natterer Sr. (1754–1823) and Maria Anna Theresia Schober (his mother), the daughter of a master baker from Laxenburg. He had a brother (Joseph Natterer, 1786–1852). Joseph Natterer Sr. was the last mounted falconer of Austria. When Francis II, Holy Roman Emperor, Emperor Franz I dissolved the falconry (''Falknerei'') in Laxenburg, he bought the collection of Joseph Natterer Sr. This contained numerous domestic birds, mammals, and insec ...

A History Of British Birds
''A History of British Birds'' is a natural history book by Thomas Bewick, published in two volumes. Volume 1, ''Land Birds'', appeared in 1797. Volume 2, ''Water Birds'', appeared in 1804. A supplement was published in 1821. The text in ''Land Birds'' was written by Ralph Beilby, while Bewick took over the text for the second volume. The book is admired mainly for the beauty and clarity of Bewick's wood-engravings, which are widely considered his finest work, and among the finest in that medium. ''British Birds'' has been compared to works of poetry and literature. It plays a recurring role in Charlotte Brontë's novel ''Jane Eyre''. William Wordsworth praised Bewick in the first lines of his poem "The Two Thieves": "Oh now that the genius of Bewick were mine, And the skill which he learned on the banks of the Tyne." The book was effectively the first "field guide" for non-specialists. Bewick provides an accurate illustration of each species, from life if possible, or from s ...

Thomas Bewick
Thomas Bewick (c. 11 August 1753 – 8 November 1828) was an English wood engraving, 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 (engraver), John Anderson, Luke Clennell, and William Harvey (artist), 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 ...

The Natural History Of Selborne
''The Natural History and Antiquities of Selborne'', or just ''The Natural History of Selborne'' is a book by English parson-naturalist Gilbert White (1720–1793). It was first published in 1789 by his brother Benjamin. It has been continuously in print since then, with nearly 300 editions up to 2007. The book was published late in White's life, compiled from a mixture of his letters to other naturalists—Thomas Pennant and Daines Barrington; a 'Naturalist's Calendar' (in the second edition) comparing phenology observations made by White and William Markwick of the first appearances in the year of different animals and plants; and observations of natural history organized more or less systematically by species and group. A second volume, less often reprinted, covered the antiquities of Selborne. Some of the letters were never posted, and were written for the book. White's ''Natural History'' was at once well received by contemporary critics and the public, and continued to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
