Branta
The black geese of the genus ''Branta'' are waterfowl belonging to the Goose, true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, Bird migration, migrating to more southerly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining Feral animal, feral population derived from introduced Canada geese is also found in New Zealand. The black geese derive their vernacular name for the prominent areas of black coloration found in all species. They can be distinguished from all other true geese by their legs and feet, which are black or very dark grey. Furthermore, they have black bills and large areas of black on the head and neck, with white (ochre in one species) markings that can be used to tell apart most species.The nēnē, which is aberrant in many respects, has no white on the head or neck and fairly little black, being quite similar to the s ...

Canada Goose
The Canada goose (''Branta canadensis''), sometimes called Canadian goose, is a large species of goose with a black head and neck, white cheeks, white under its chin, and a brown body. It is native to the arctic and temperate regions of North America, and it is occasionally found during bird migration, migration across the Atlantic in northern Europe. It has been introduced to France, the United Kingdom, Ireland, Scandinavia, New Zealand, Japan, Chile, Argentina, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water, the Canada goose is also common in Brackish water, brackish marshes, estuaries, and lagoons. Extremely adept at urban wildlife, living in human-altered areas, Canada geese have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to it often being considered a pest (orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branta Ruficollis
The red-breasted goose (''Branta ruficollis'') is a brightly marked species of goose in the genus ''Branta'' from Eurasia. It is currently classified as vulnerable by the IUCN. Taxonomy and etymology The red-breasted goose is sometimes placed in its own genus ''Rufibrenta'' but appears close enough to the brant goose (''Branta bernicla'') to make this unnecessary, despite its distinct appearance. Today all major authorities include the red-breasted goose in ''Branta''. Genetic studies indicate that the red-breasted goose may be one the few known examples of hybrid speciation in birds, being the result of ancient interbreeding between the ancestral brant goose and white-cheeked goose (the latter being the ancestral species that later split into all today's ''Branta'' species, except the brant and red-breasted geese). This interbreeding appears to have happened at least 3.5 million years ago, with the lineage of the red-breasted goose following its own evolutionary path since t ...

Branta Leucopsis
The barnacle goose (''Branta leucopsis'') is a species of goose that belongs to the genus ''Branta'' of black geese, which contains species with extensive black in the plumage, distinguishing them from the grey '' Anser'' species. Despite its superficial similarity to the brant goose, genetic analysis has shown its closest relative is the cackling goose. Taxonomy and naming The barnacle goose was first classified taxonomically by Johann Matthäus Bechstein in 1803. ''Branta'' is a Latinised form of Old Norse ''Brandgás'', "burnt lackgoose" and the specific epithet is from the Ancient Greek ''leukos'' "white", and ''opsis'' "faced". In the mediaeval period, the barnacle goose and the similar brant goose were not distinguished, and were formerly believed to spawn from the goose barnacle. This gave rise to the English name of the barnacle goose and the scientific name of the brant goose. The barnacle myth can be dated back to at least the 12th century. Gerald of Wales claimed to ...

Nēnē
The Nene (''Branta sandvicensis''), also known as the nēnē or the Hawaiian goose, is a species of bird Endemism in birds, endemic to the Hawaiian Islands. The Nene is exclusively found in the wild on the islands of Maui, Kauai, Kauai, Molokai, and Hawaii (island), Hawaii. In 1957, it was designated as the official List of U.S. state birds, state bird of Hawaii, the state of Hawaii. The Hawaiian language, Hawaiian name ''nēnē'' comes from its soft call. The specific name ''sandvicensis'' refers to the Sandwich Islands, a former name for the Hawaiian Islands. Taxonomy The Type (biology), holotype specimen of ''Anser sandvicensis'' VigorsList Anim. Garden Zool. Soc., ed.3, June 1833, p.4. is held in the vertebrate zoology collection at World Museum, National Museums Liverpool, with accession number NML-VZ T12706.

Brant Goose
The brant or brent goose (''Branta bernicla'') is a small goose of the genus ''Branta''. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The Brent oilfield was named after the species. Taxonomy The brant was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas bernicla''. Linnaeus specified the type locality as Europe but in 1761 restricted it to Sweden. The brant is now one of six species placed in the genus ''Branta'' that was introduced in 1769 by the Austrian naturalist Giovanni Antonio Scopoli. The genus name ''Branta'' is a Latinised form of Old Norse ''brandgás'', "burnt (black) goose". The specific epithet ''bernicla'' is Medieval Latin for barnacle. The brant and the similar barnacle goose were previously considered to be the same species and believed to be the same creature as the barnacle. That myth c ...

Branta Hutchinsii
The cackling goose (''Branta hutchinsii'') is a species of goose found in North America and East Asia. Systematics The genus name ''Branta'' is a Latinised form of Old Norse ''Brandgás'', "burnt (black) goose", and the specific epithet ''hutchinsii'' commemorates English surgeon Thomas Hutchins who was employed by the Hudson's Bay Company. The cackling goose was originally considered the same species or a subspecies of the Canada goose, but in July 2004 the American Ornithologists' Union's (AOU) Committee on Classification and Nomenclature split the two into two species, making cackling goose into a full species with the scientific name ''Branta hutchinsii''. The British Ornithologists' Union (BOU) followed suit in June 2005. The AOU has divided the many associated subspecies between both animals. To the present species were assigned: *Richardson's cackling goose (''B. h. hutchinsii'') * Aleutian cackling goose (''B. h. leucopareia'') * Small cackling goose (''B. h. minima'') ...

Goose
A goose (: geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera '' Anser'' (grey geese and white geese) and '' Branta'' (black geese). Some members of the Tadorninae subfamily (e.g., Egyptian goose, Orinoco goose) are commonly called geese, but are not considered "true geese" taxonomically. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to such bird of either sex, but when paired with "gander", "goose" refers specifically to a female one ("gander" referring to a male). Young birds before fledging are called goslings. The collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of Proto-Indo-European ''*ǵʰh₂éns''. In Germanic lang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resident Bird
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. 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 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.
