Podilymbus
''Podilymbus'' is a genus of birds in the Podicipedidae, Grebe family, the genus name is derived from Latin ''Podilymbus'', a contraction (grammar), contraction of ''podicipes'' ("feet at the buttocks", from ''podici-'', "rump-" + ''pes'', "foot")—the origin of the name of the grebe order (biology), order—and Ancient Greek ''kolymbos'', "diver".Cabard P. and Chauvet B.

Pied-billed Grebe
The pied-billed grebe (''Podilymbus podiceps'') is a species of the grebe family of water birds. Because the Atitlán grebe (''Podilymbus gigas'') has become extinct, the Pied-Billed Grebe is now the sole extant member of the genus ''Podilymbus''. The pied-billed grebe is primarily found in ponds throughout the Americas. Other names of this grebe include American dabchick, rail, dabchick, Carolina grebe, devil-diver, dive-dapper, dipper, hell-diver, pied-billed dabchick, pied-bill, thick-billed grebe, and water witch. Taxonomy and name The pied-billed grebe was described by Carl Linnaeus in the 10th edition of his ''Systema Naturae'' in 1758 as ''Colymbus podiceps''. The binomial name is derived from Latin ''Podilymbus'', a contraction of ''podicipes'' ("feet at the buttocks", from ''podici-'', "rump-" + ''pes'', "foot")—the origin of the name of the grebe order—and Ancient Greek ''kolymbos'', "diver", and ''podiceps'', "rump-headed", from ''podici-'' + New Latin ''ceps''. ...

Atitlán Grebe
The Atitlán grebe (''Podilymbus gigas''), also known as giant grebe, giant pied-billed grebe, or poc, is an extinct water bird, a relative of the pied-billed grebe. It was endemic at the Lago de Atitlán in Guatemala at an altitude of 1700 m asl. It was described in 1929 by Ludlow Griscom based on a specimen collected in 1926 and had been overlooked in the past. American ecologist Anne LaBastille observed the decline of this species over a period of 25 years. It was declared extinct by 1990. Description The Atitlán grebe reached a length of about 46–50 cm. The call and appearance were similar to the much smaller pied-billed grebe. The bill was large and pied but the color varied from white in the spring to brown in other seasons. The plumage was mainly dark brown with white-flecked flanks and grey on the ears. The underparts were dark grey flecked with white. The head was almost black and the neck was glossy flecked with dark brown in the spring and white in the winter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird Genera With One Living Species
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Paleosubspecies
A chronospecies is a species derived from a sequential development pattern that involves continual and uniform changes from an extinct ancestral form on an evolutionary scale. The sequence of alterations eventually produces a population that is physically, morphologically, and/or genetically distinct from the original ancestors. Throughout the change, there is only one species in the lineage at any point in time, as opposed to cases where divergent evolution produces contemporary species with a common ancestor. The related term paleospecies (or palaeospecies) indicates an extinct species only identified with fossil material. That identification relies on distinct similarities between the earlier fossil specimens and some proposed descendant although the exact relationship to the later species is not always defined. In particular, the range of variation within all the early fossil specimens does not exceed the observed range that exists in the later species. A paleosubspecies (or ...

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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Taxa
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
