Branta
The black geese of the genus ''Branta'' are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southernly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining 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 swan goose in the color pattern of ...

Canada Goose
The Canada goose (''Branta canadensis''), or Canadian goose, is a large wild 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 migration across the Atlantic in northern Europe. It has been introduced to the United Kingdom, Ireland, Finland, Sweden, Denmark, 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 marshes, estuaries, and lagoons. Extremely adept at 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 its often being considered a pest species because of its excrement, its depredation of crops, its n ...

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 th ...

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 largely black plumage, distinguishing them from the grey ''Anser'' species. Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage. 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 (black) goose" and the specific epithet is from the Ancient Greek ''leukos'' "white", and ''opsis'' "faced". The barnacle goose and the similar brant goose were previously considered one species, 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. It is sometimes claimed that the word comes from a Celtic word for "limpet", but the sense-history ...

Nēnē
The nene (''Branta sandvicensis''), also known as the nēnē or the Hawaiian goose, is a species of bird endemic to the Hawaiian Islands. The nene is exclusively found in the wild on the islands of Oahu, Maui, Kauai, Molokai, and Hawaii. In 1957, it was designated as the official state bird of the state of Hawaii. The 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 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. The specimen was collected from the Sandwich Islands (Hawaiian Islands) and came to the Liverpool national collection via the Museum of the Zoological Society of London collection, Thomas Campbell Eyton’s collection, and Henry Baker Tristram’s collection.

Branta Hutchinsii
The cackling goose (''Branta hutchinsii'') is a species of goose found in North America. Description The black head and neck with white "chinstrap" distinguish this goose from all other geese except the larger Canada goose (''Branta canadensis'') and the similarly sized barnacle goose (''B. leucopsis''). There are up to 5 subspecies of cackling goose, of varying sizes and plumage details. The female looks virtually identical but is slightly lighter and has a different voice. Some are hard to distinguish from the Canada goose, with which the cackling goose was long assumed to form one species, the cackling goose and the smaller Canada goose subspecies being called the lesser Canada goose. The smallest Cackling geese (''B. h. minima'') are much smaller than any Canada goose, but the subspecies ''B. h. hutchinsii'', at up to , grows to the same size as some Canada geese. The distinctness of the extinct population of the Komandorski and Kuril Islands ''B. h. asiatica'' is controvers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Description The brant is a small goose with a short, stubby bill. It measures long, across the wings and weighs . The under-tail is pure white, and the tail black and very short (the shortest of any goose). The species is divided into three subspecies: * Dark-bellied brant goose ''B. b. bernicla'' (Linnaeus, 1758) * Pale-bellied brant goose ''B. b. hrota'' ( Müller, 1776) (also known as light-bellied brent goose in Europe, and Atlantic brant in North America) * Black brant goose ''B. b. nigricans'' (Lawrence, 1846) (sometimes also known as the Pacific brant in North America) Some DNA evidence suggests that these forms are genetically distinct; while a split into three separate species has been proposed, it is not wide ...

Goose
A goose ( : geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera ''Anser'' (the grey geese and white geese) and '' Branta'' (the black geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. 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 either a male or female bird, but when paired with "gander", refers specifically to a female one (the latter 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,''*ghans-''. In Germanic languages, the root gave Old English ''gōs'' with the plural ''gēs'' and ''gandres'' (b ...

Resident Bird
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 we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
