Hawaiian Stilt
The Hawaiian stilt (''Himantopus mexicanus knudseni'') is an endangered Hawaiian subspecies of the black-necked stilt (''H. mexicanus'') species. It is a long-legged, slender shorebird with a long, thin beak. Other common names include the Hawaiian black-necked stilt, the aeʻo (from a Hawaiian name for the bird and word for stilts), the kukuluaeʻo (a Hawaiian name for the bird and word for “one standing high”), or it may be referred to as the Hawaiian subspecies of the black-necked stilt. Taxonomy The Hawaiian stilt is usually classified as a subspecies of the black-necked stilt, ''Himantopus himantopus knudseni'', or even as its own species, ''Himantopus knudseni''. Description The Hawaiian stilt grows up to in length. It has a black back from head to tail, with a white forehead, face, and underside. Its bill is thin, long and black, and its legs are very long and pink. Sexes are similar, except that the female has a tinge of brown on its back, while the male's back is ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

Endangered Fauna Of Hawaii
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Himantopus
Stilt is a common name for several species of birds in the family Recurvirostridae, which also includes those known as avocets. They are found in brackish or saline wetlands in warm or hot climates. They have extremely long legs, hence the group name, and long thin bills. Stilts typically feed on aquatic insects and other small creatures and nest on the ground surface in loose colonies. Most sources recognize 6 species in 2 genera, although the white-backed and Hawaiian stilts are occasionally considered subspecies of the black-necked stilt. The genus ''Charadrius'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the black-winged stilt (''Himantopus himantopus'') as the type species. The generic name ''Himantopus'' comes from the Ancient Greek meaning "strap-leg". Species The genus ''Himantopus'' contains five species: * Black-winged stilt, ''Himantopus himantopus'' * White-backed stilt, ''Himantopus melanurus'' * Pied stilt The pied stilt ( ...

Black-crowned Night Heron
The black-crowned night heron (''Nycticorax nycticorax''), or black-capped night heron, commonly shortened to just night heron in Eurasia, is a medium-sized heron found throughout a large part of the world, including parts of Europe, Asia, and North and South America. In Australasia it is replaced by the closely related nankeen night heron, with which it has hybridized in the area of contact. Taxonomy The black-crowned night heron was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with herons, cranes and egrets in the genus '' Ardea'' and coined the binomial name ''Ardea nicticorax''. It is now placed in the genus ''Nycticorax'' that was introduced in 1817 by the English naturalist Thomas Forster for this species. The epithet ''nycticorax'' is from Ancient Greek and combines ''nux'', ''nuktos'' meaning "night" and ''korax'' meaning "raven". The word was used by authors such as Aristotle and Hes ...

Pueo
The pueo (''Asio flammeus sandwichensis'') is a subspecies of the short-eared owl and is endemic to Hawaii. The pueo is one of the more famous of the various physical forms assumed by '' aumākua'' (ancestor spirits) in Hawaiian culture. Pueo inhabit forests and grasslands throughout the islands of Hawaiʻi, although their numbers seem to be declining, particularly in the last two decades, and especially on the island of Oʻahu, upon which they were at one time numerous. Pueo is listed by the state of Hawaiʻi as an endangered species on the island of Oʻahu. Taxonomy This taxon was first named by Andrew Bloxam (as the species ''Strix sandwichensis''). He saw it, although did not collect a specimen, while in the Hawaiian Islands in 1825 as the naturalist on board HMS ''Blonde''. It is now considered to be a subspecies of the short-eared owl, ''Asio flammeus'', although Storrs Olson does not consider it to be distinct from ''Asio flammeus flammeus''.

Mongoose
A mongoose is a small terrestrial carnivorous mammal belonging to the family Herpestidae. This family is currently split into two subfamilies, the Herpestinae and the Mungotinae. The Herpestinae comprises 23 living species that are native to southern Europe, Africa and Asia, whereas the Mungotinae comprises 11 species native to Africa. The Herpestidae originated about in the Early Miocene and genetically diverged into two main genetic lineages between 19.1 and . Etymology The English word "mongoose" used to be spelled "mungoose" in the 18th and 19th centuries. The name is derived from names used in India for ''Herpestes'' species: or in classical Hindi; in Marathi; in Telugu; , and in Kannada. The form of the English name (since 1698) was altered to its "-goose" ending by folk etymology. The plural form is "mongooses". Characteristics Mongooses have long faces and bodies, small, rounded ears, short legs, and long, tapering tails. Most are brindled or grizzly; a few h ...

NatureServe Conservation Status
The NatureServe conservation status system, maintained and presented by NatureServe in cooperation with the Natural Heritage Network, was developed in the United States in the 1980s by The Nature Conservancy (TNC) as a means for ranking or categorizing the relative imperilment of species of plants, animals, or other organisms, as well as natural ecological communities, on the global, national or subnational levels. These designations are also referred to as NatureServe ranks, NatureServe statuses, or Natural Heritage ranks. While the Nature Conservancy is no longer substantially involved in the maintenance of these ranks, the name TNC ranks is still sometimes encountered for them. NatureServe ranks indicate the imperilment of species or ecological communities as natural occurrences, ignoring individuals or populations in captivity or cultivation, and also ignoring non-native occurrences established through human intervention beyond the species' natural range, as for example w ...

Ni'ihau
Niihau ( Hawaiian: ), anglicized as Niihau ( ), is the westernmost main and seventh largest inhabited island in Hawaii. It is southwest of Kauaʻi across the Kaulakahi Channel. Its area is . Several intermittent playa lakes provide wetland habitats for the Hawaiian coot, the Hawaiian stilt, and the Hawaiian duck. The island is designated as critical habitat for ''Brighamia insignis'', an endemic and endangered species of Hawaiian lobelioid. The United States Census Bureau defines Niihau and the neighboring island and State Seabird Sanctuary of Lehua as Census Tract 410 of Kauai County, Hawaii. Its 2000 census population was 160, most of whom are native Hawaiians; Its 2010 census population was 170. At the 2020 census, the population had fallen to 84. Elizabeth Sinclair purchased Niihau in 1864 for from the Kingdom of Hawaii. The island's private ownership passed on to her descendants, the Robinsons. During World War II, the island was the site of the Niihau incident, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
