Stilt Sandpiper By Dan Pancamo
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, ''Himantopus leucoc ...

Black-winged Stilt
The black-winged stilt (''Himantopus himantopus'') is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, ''Himantopus himantopus'', is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of ''H. himantopus'' ''sensu lato''. Meanwhile, the black-necked (''H. mexicanus'') and white-backed stilts (''H. melanurus'') both inhabit the Americas; the pied stilt (''H. leucocephalus'') ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. Taxonomy The black-winged stilt was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the plovers in the genus ''Charadrius'' and coined the binomial name ''Charadrius himantopus''. He specified the type locality as ...

Pied Stilt
The pied stilt (''Himantopus leucocephalus''), also known as the white-headed stilt, is a shorebird in the Family (biology), family Recurvirostridae. It is widely distributed with a large total population size and apparently stable population trend, occurring in Malaysia, Japan, the Philippines, Brunei, Christmas Island, Indonesia, Palau, Papua New Guinea, Australia, and New Zealand. It is listed as Least Concern on the IUCN Red List. It is sometimes considered a subspecies of the black-winged stilt (''H. himantopus''). Taxonomy ''Himantopus leucocephalus'' was the scientific name proposed by John Gould in 1837 who described a pied stilt from Australia. Description The pied stilt grows to a length of about with a wingspan of about . The back of the head and neck, the back and the upper surfaces of the wings are glossy greenish-black. The undersides of the wings are plain black and the remainder of the plumage is white, apart from the tail feathers which are tinged with grey. T ...

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that is, during the Late Miocene.

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Black Stilt
The black stilt (''Himantopus novaezelandiae'') or kakī (Māori language, Māori) is a wading bird found in New Zealand. It is one of the world's rarest birds, with 169 adults surviving in the wild as of May 2020. Adult kakī have distinctive black plumage, long pink legs, and a long thin black bill. Black stilts largely breed in the Mackenzie Basin in the South Island, and are threatened by introduced Cats in New Zealand, feral cats, ferrets, and hedgehogs as well as habitat degradation from hydroelectric dams, agriculture, and invasive weeds. Taxonomy and systematics Black stilts are one of several species in the genus Stilt, ''Himantopus'', classified along with avocets in the family Recurvirostridae. Although genetically and behaviourally distinct from Black-winged stilt, pied stilts (''Himantopus himantopus''), they are able to successfully hybridise with them. Hybridisation and dilution of the gene pool is one reason black stilts are threatened with extinction. Black an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mexicanus knudseni'', or sometimes as a full species, ''Himantopus knudseni''. Description The Hawaiian stilt grows up to in length. It has a dark 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. They are sexually dimorphic, differing in the colour and lustre of their back feathers. Females hav ...

Black-necked Stilt
The black-necked stilt (''Himantopus mexicanus'') is a locally abundant shorebird of North and South American wetlands and coastlines. It is found from the coastal areas of California through much of the interior western United States and along the Gulf of Mexico as far east as Florida, then south through Central America and the Caribbean to Brazil, Peru and the Galápagos Islands, with an isolated population, the Hawaiian stilt, in Hawaii. The northernmost populations, particularly those from inland, are migratory, wintering from the extreme south of the United States to southern Mexico, rarely as far south as Costa Rica; on the Baja California peninsula it is only found regularly in winter. Some authorities, including the IUCN, treat it as a synonym of ''Himantopus himantopus''. Taxonomy It is often treated as a subspecies of the common or black-winged stilt, using the trinomial name ''Himantopus himantopus mexicanus''. However, the American Ornithological Society, AOS has al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-backed Stilt
The white-backed stilt (''Himantopus melanurus'') is a locally abundant shorebird of South American wetlands and coastlines. It is found from northwest Brazil to southwest Peru and southcentral Argentina. Taxonomy It is sometimes treated as a subspecies of the common or black-winged stilt, using the trinomial name ''Himantopus himantopus melanurus''. The AOS considers it a subspecies of the black-necked stilt, where it is considered parapatric and intergrading to some extent with its northern relative where their ranges meet, and would warrant inclusion with the black-necked stilt when this is separated specifically. Distribution and habitat The white-backed stilt is found in estuarine, lacustrine, salt pond and emergent wetland habitats; it is generally a lowland bird but is commonly seen in llanos habitat. Food and feeding The white-backed stilt forages by probing and gleaning primarily in mudflats and lakeshores, but also in very shallow waters near shores; it seeks out a ...

Mathurin Jacques Brisson
Mathurin Jacques Brisson (; 30 April 1723 – 23 June 1806) was a French zoologist and natural philosophy, natural philosopher. Brisson was born on 30 April 1723 at Fontenay-le-Comte in the Vendée department of western France. Note that page 141 is before page 140. His parents wished him to take ecclesiastic orders, but in 1747, he abandoned his studies, and from 1749, was employed by the wealthy French naturalist René Antoine Ferchault de Réaumur as the curator of a large private collection of objects related to natural history that de Réaumur kept at his ancestral home at Réaumur, Vendée, Réaumur in the Vendée. Originally published by F. W. Peters in 1951 as ''Die Entwicklung Der Ornithologie von Aristoteles bis zur Gegenwart''. Brisson became interested in the classification of animals and was influenced by the works of Carl Linnaeus and Jacob Theodor Klein. His book ''Le Règne animal'' was published in 1756, and the highly regarded six-volume work ''Ornithologie'' wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
