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. In the era following western contact, habitat loss and avian disease are thought to have had the greatest effect on endemic bird species in Hawaii, although native peoples are implicated in the loss of dozens of species before the arrival of Captain Cook and others, in large part due to the arrival of the Polynesian rat (''Rattus exulans'') which came along with the first Polynesians. 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 ...

Endemism In Birds
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Anatidae
The Anatidae are the biological family (biology), family of water birds that includes ducks, goose, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for aquatic locomotion, swimming, floating on the water surface, and, in some cases, diving in at least shallow water. The family contains around 174 species in 43 genus, genera (the magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae). They are generally herbivorous and are monogamy in animals, monogamous breeders. A number of species undertake bird migration, annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Coot
The 'ʻAlae keʻokeʻo (''Fulica alai''), also known as the ''Hawaiian coot'' in English, is a bird in the rail family, Rallidae, that is endemic to Hawaiʻi. In Hawaiian, ''ʻalae'' is a noun and means ''mud hen''. ''Kea'' or its synonym ''keo'' is an adjective for ''white''. It is similar to the American coot at in length and weighing around . It has black plumage and a prominent white frontal shield. Its natural habitats are freshwater lakes, freshwater marshes, coastal saline lagoons, and water storage areas. The bird was federally listed in October 1970 as an endangered species and is considered both endemic and endangered by the state of Hawaiʻi. It is threatened by habitat loss and introduced predators such as the small Asian mongoose. The Makalawena Marsh on the Big Island of Hawaiʻi has been listed as a National Natural Landmark to preserve one of its last nesting areas.

Hawaiian Gallinule
The Hawaiian gallinule (''Gallinula galeata sandvicensis'') is an endangered species, endangered chicken-sized water bird in the Rallidae, rail family (biology), family. It is also variously known as the Hawaiian common gallinule, Hawaiian moorhen, Hawaiian common moorhen, mudhen, or ''‘alae ‘ula'' (“burnt forehead” - for its prominent red frontal shield) in Hawaiian language, Hawaiian, and sometimes misleadingly as the Hawaiian red coot. It is a subspecies of the common gallinule that is endemism, endemic to the tropics, tropical Hawaiian Islands of the north-central Pacific Ocean. It is dependent on freshwater wetland habitats with dense emergent plant, emergent vegetation for nesting. Once found on most of the main islands of the Hawaiian archipelago, it has undergone a major population and range decline and is now a resident breeder only on Kaua'i and O'ahu. Causes of the decline were mainly loss of habitat, hunting and predation by introduced animals, with numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Rail
The Hawaiian rail (''Zapornia sandwichensis''), Hawaiian spotted rail, or Hawaiian crake is an extinct species of diminutive Rallidae, rail that lived on Hawaii (island), Big Island of Hawaii, Hawaii. Taxonomy Considerable confusion has been created by the existence of two distinct forms. While it cannot be completely excluded that early specimens were collected on another island, only Oahu, Oahu and Kauai, Kauai seem possible given the history of the specimens' collection, and only on the latter island is a similar-sized species now known to have once existed. However, the bones from Kauai are in the upper size range of those found of ''sandwichensis'', while the specimens of the lighter form are all of smaller birds. This bird was only the size of a Laysan rail; it may have been the bird named ''iao'' or ''iao'', which would place its extinction at a relatively recent date. Also, there are some bones of a third species, approximately 15% larger than ''Z. sandwichensis'', fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laysan Rail
The Laysan rail or Laysan crake (''Zapornia palmeri'') was a flightless bird endemic to the Northwestern Hawaiian Islands, Northwest Hawaiian Island of Laysan. This small island was and still is an important seabird colony, and sustained a number of Endemism, endemic species, including the rail. It became extinct due to habitat loss by domestic rabbits, and ultimately World War II. Taxonomy Its scientific name honours Henry Palmer, who collected in the Hawaiian Islands for Walter Rothschild, 2nd Baron Rothschild, Walter Rothschild. The following cladogram shows the placement of the Laysan rail among other rails, according to Slikas and colleagues, 2002: Description It was a small bird ( from beaktip to "tail" tip, fully stretched out), a Flightless bird, flightless member of the Rallidae, rail family. Tail and wings had been reduced in the course of its evolution to lengths of merely and , respectively, and it only had 8 remiges, primaries as opposed to 10 in volant rails ...

Rallidae
Rails (avian family Rallidae) are a large, Cosmopolitan distribution, cosmopolitan family (biology), family of small- to medium-sized terrestrial and/or semi-amphibious birds. The family exhibits considerable diversity in its forms, and includes such ubiquitous species as the crakes, coots, and gallinule; other rail species are extremely rare or endangered. Many are associated with wetland habitats, some being semi-aquatic like waterfowl (such as the coot), but many more are wading birds or shorebirds. The ideal rail habitats are marsh areas, including rice paddy, rice paddies, and flooded fields or open forest. They are especially fond of dense vegetation for nesting.Horsfall & Robinson (2003): pp. 206–207 The rail family is found in every Terrestrial animal, terrestrial habitat with the exception of dry desert, Polar climate, polar or freezing regions, and Alpine climate, alpine areas (above the snow line). Members of Rallidae occur on every continent except Antarctica. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Hawk
The Hawaiian hawk or ''io'' (''Buteo solitarius'') is a raptor in the genus '' Buteo'' endemic to Hawaii, currently restricted to the Big Island. The ''io'' is one of two extant birds of prey that are native to Hawaii, the other being the '' pueo'' (Hawaiian short-eared owl) and fossil evidence indicates that it inhabited the island of Hawaii, Molokai, Oahu, Maui and Kauai at one time. Today, it is known to breed only on the Big Island, in stands of native ''ōhia lehua'' (''Metrosideros polymorpha'') trees. The species was protected as an endangered species in the United States, but was delisted in 2020. However, the IUCN classifies the species as Near Threatened. NatureServe considers the species ''Vulnerable''. Description The Hawaiian hawk measures approximately in length. The female, which weighs on average, is larger than the male, which averages . Two color phases exist: a dark phase (dark brown head, breast, and underwings), and a light color phase (dark head, light ...

Accipitridae
The Accipitridae () is one of the four families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents (except Antarctica) and a number of oceanic island groups. Some species are migratory. The family contains 256 species which are divided into 12 subfamilies and 75 genera. Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family ( Pandionidae), as is the secretary bird ( Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data indicate the accipitrids analysed are indeed a distinct monophyletic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-footed Albatross
The black-footed albatross (''Phoebastria nigripes'') is a large seabird of the albatross family Diomedeidae from the North Pacific. All but 2.5% of the population is found among the Northwestern Hawaiian Islands. It is one of three species of albatross that range in the northern hemisphere, nesting on isolated tropical islands. Unlike many albatrosses, it is dark plumaged. Taxonomy Black-footed albatrosses are a type of albatross that belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is us ...

Laysan Albatross
The Laysan albatross (''Phoebastria immutabilis'') is a large seabird that ranges across the North Pacific. The Northwestern Hawaiian Islands are home to 99.7% of the population. This small (for its family (biology), family) gull-like albatross is the second-most common seabird in the Hawaiian Islands, with an estimated population of 1.18 million birds, and is currently expanding (or possibly re-expanding) its range to new islands. The Laysan albatross was first described as ''Diomedea immutabilis'' by Walter Rothschild, 2nd Baron Rothschild, Lionel Walter Rothschild, in 1893, on the basis of a specimen from Laysan Island.Robertson, C. J. R. (2003) Etymology It is named for Laysan, one of its breeding colonies in the Northwestern Hawaiian Islands and the island where the type specimen was collected. The genus name, ''Phoebastria'', comes from Greek ''phoibastria'', meaning a prophetess. The species name, ''immutabilis'', is Latin for "unchanging" and refers to the similarity of im ...

Diomedeidae
Albatrosses, of the biological family (biology), family Diomedeidae, are large seabirds related to the procellariidae, procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific Ocean, Pacific. They are absent from the North Atlantic Ocean, Atlantic, although fossil remains of short-tailed albatross show they lived there up to the Pleistocene, and occasional Vagrancy (biology), vagrants are found. Great albatrosses are among the largest of bird flight, flying birds, with wingspans reaching up to and bodies over in length. The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are Bird colon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
