List Of Birds Of Hawaii
This list of birds of Hawaii is a comprehensive listing of all the bird species seen naturally in the U.S. state of Hawaii as determined by Robert L. and Peter Pyle of the Bishop Museum, Honolulu, and modified by subsequent taxonomic changes. The scope of this list encompasses the entire Hawaiian Islands chain, from Kure Atoll in the Northwestern Hawaiian Islands to the north, to the "Big Island" of Hawaii to the south. The list contains 337 species. Of them, 64 are or were endemic to the islands, 130 are vagrants and 52 were introduced by humans. Thirty-three of the 64 endemic species are extinct and two formerly established introduced species were extirpated. The list does not include introduced species that have not become established. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Birds'', 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Endemic Birds Of Hawaii
There are 71 known taxa of birds endemic to the Hawaiian Islands, of which 30 are extinct, 6 possibly extinct and 30 of the remaining 48 species and subspecies are listed as endangered or threatened by the United States Fish and Wildlife Service. Habitat loss and avian disease are thought to have had the greatest effect on endemic bird species in Hawaii. List of species The following is a list of bird species and subspecies endemic to the Hawaiian Islands: Procellariidae * Hawaiian petrel or uau, ''Pterodroma sandwichensis'' * Newell's shearwater or ao, ''Puffinus newelli'' * Bryan's shearwater, ''Puffinus bryani'' ('' P. assimilis'': ) * Bonin petrel, ''Pterodroma hypoleuca'' 99% of the total population breeds on the Northwestern Hawaiian Islands Anatidae * Hawaiian goose or nēnē, ''Branta sandvicensis'' * Hawaiian duck or koloa maoli, ''Anas wyvilliana'' * Laysan duck, ''Anas laysanensis'' Diomedeidae * Laysan albatross, ''Phoebastria immutabilis'' 99.7% of ...

Hawaiian Duck
The Hawaiian duck (''Anas wyvilliana'') or koloa is a species of bird in the family Anatidae that is endemic to the large islands of Hawaii. Taxonomically, the koloa is closely allied with the mallard (''A. platyrhynchos''). It differs in that it is monochromatic (with similarly marked males and females) and non-migratory. As with many duck species in the genus ''Anas'', Hawaiian duck and mallards can interbreed and produce viable offspring, and the koloa has previously been considered an island subspecies of the mallard. However, all major authorities now consider this form to be a distinct species within the mallard complex. Recent analyses indicate that this is a distinct species that arose through ancient hybridization between mallard and Laysan duck (''Anas laysanensis''). The native Hawaiian name for this duck is ''koloa maoli'' (meaning "native duck"), or simply koloa. This species is listed as endangered by the IUCN Red List of Threatened Species, and its population trend is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garganey
The garganey (''Spatula querquedula'') is a small dabbling duck. It breeds in much of Europe and across the Palearctic, but is strictly migratory, with the entire population moving to southern Africa, India (in particular Santragachi), Bangladesh (in the natural reservoirs of Sylhet district) and Australasia during the winter of the Northern hemisphere, where large flocks can occur. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. Like other small ducks such as the Eurasian teal, this species rises easily from the water with a fast twisting wader-like flight. Their breeding habitat is grassland adjacent to shallow marshes and steppe lakes. Taxonomy The first formal description of the garganey was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He introduced the binomial name ''Anas querquedula''. A molecular phylogentic study comparing mitochondrial DNA sequences publis ...

Baikal Teal
The Baikal teal (''Sibirionetta formosa''), also called the bimaculate duck or squawk duck, is a dabbling duck that breeds in eastern Russia and winters in East Asia. Taxonomy The first formal description of the Baikal teal was by the German naturalist Johann Gottlieb Georgi in 1775 under the binomial name ''Anas formosa''. A molecular phylogentic study published in 2009 found that the genus ''Anas'' as then defined was non-monophyletic. Based on this analysis the genus was split into four proposed genera with the Baikal teal placed in the resurrected genus ''Sibirionetta'' that had been introduced by the German zoologist Hans von Boetticher in 1929. The name ''Sibirionetta'' is derived from the Latin ''sibiricus'' for Siberia and the Ancient Greek ''nētta'' for a duck. The specific epithet ''formosa'' is from the Latin ''formosus'' for "beautiful". Description At between , this duck is slightly larger and longer-tailed than the common teal. The breeding male is unmistak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra Swan
The tundra swan (''Cygnus columbianus'') is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan (''Cygnus bewickii'') of the Palaearctic and the whistling swan (''C. columbianus'') proper of the Nearctic. Birds from eastern Russia (roughly east of the Taymyr Peninsula) are sometimes separated as the subspecies ''C. c. jankowskii'', but this is not widely accepted as distinct, with most authors including them in ''C. c. bewickii''. Tundra swans are sometimes separated in the subgenus ''Olor'' together with the other Arctic swan species. Bewick's swan was named in 1830 by William Yarrell after the engraver Thomas Bewick, who specialised in illustrations of birds and animals. ''Cygnus'' is the Latin for "swan", and '' columbianus'' comes from the Columbia River, the type locality. Description ''C. columbianus'' is the smallest of the Holarctic swans, at in length, in wingspan and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Goose
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. It is tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cackling Goose
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 ...

Greater White-fronted Goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose related to the smaller lesser white-fronted goose (''A. erythropus''). It is named for the patch of white feathers bordering the base of its bill, in fact ''albifrons ''comes from the Latin ''albus'' "white" and ''frons "''forehead". In Europe it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. Description Greater white-fronted geese are in length, have a wingspan, and weigh . They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Goose
The snow goose (''Anser caerulescens'') is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage. The species was previously placed in the genus ''Chen'', but is now typically included in the "gray goose" genus ''Anser''. Snow geese breed north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and spend winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico. Snow goose populations increased dramatically in the 20th century. Taxonomy In 1750 the English naturalist George Edwards included an illustration and a description of the snow goose in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The blue-winged goose". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay a ...

Emperor Goose
The emperor goose (''Anser canagicus''), also known as the beach goose or the painted goose, is a waterfowl species in the family Anatidae, which contains the ducks, geese, and swans. It is blue-gray in color as an adult and grows to in length. Adults have a black chin and throat, a pink bill, yellow-orange legs, and a white head, which often turns reddish-brown in summer. In the winter, the emperor goose lives in mudflats and coasts in Alaska and occasionally Canada and the contiguous United States. In the summer, it bird migration, migrates northerly several hundred miles to arctic and sub-arctic climates, where older individuals breed Monogamy in animals, monogamously. Nests are constructed in holes and built up with vegetation and feathers. Eggs hatch in late June and early July, and goslings leave the nest the day they hatch. The species is an omnivore, and makes vocalizations that are more nasal than those of other geese. Listed as near threatened by the International Union ...
