Harlequin Duck
The harlequin duck (''Histrionicus histrionicus'') is a small sea duck. It takes its name from Harlequin (Italian ''Arlecchino'', French ''Arlequin''), a colourfully dressed character in Commedia dell'arte. The species name comes from the Latin word "histrio", meaning "actor". Other names include painted duck, totem pole duck, rock duck, glacier duck, mountain duck, white-eyed diver, squeaker, lords and ladies and blue streak. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the harlequin duck in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Dusky and Spotted Duck". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from Newfoundland in eastern Canada. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the harlequin duck with the ducks, geese and swans in the genus ''Ana ...

René Primevère Lesson
René (''Born again (Christianity), born again'' or ''reborn'' in French language, French) is a common given name, first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * Ren ...

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] |

Bird Measurement
Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations Intraspecific variability, within species, between the sexes and depending on Biomarkers of aging, age and condition. For measurements to be useful, they must be well-defined to be consistent and comparable with those taken by others or at other points in time. Measurements can be useful to identify species, quantify functional and ecomorphology, ecomorphological differences, study growth, variation between geographically separated forms, identify Sexual dimorphism measures, differences between the sexes, age or otherwise characterize individual birds. While certain measurements are regularly taken to study living birds, others apply only to specimens in bird collections or are measurable only in the labo ...

Speculum Feathers
The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or ''remiges'', of some birds. Examples of the colour(s) of the speculum in a number of ducks are: * Common teal and green-winged teal: Iridescent green edged with buff. * Blue-winged teal: Iridescent green.

Melanitta
The scoters are stocky seaducks in the genus ''Melanitta''. The drakes are mostly black and have swollen bills, the females are brown. They breed in the far north of Europe, Asia, and North America, and winter further south in temperate zones of those continents. They form large flocks on suitable coastal waters. These are tightly packed, and the birds tend to take off together. Their lined nests are built on the ground close to the sea, lakes or rivers, in woodland or tundra. These species dive for crustaceans and molluscs. Taxonomy The genus ''Melanitta'' was introduced by the German zoologist Friedrich Boie in 1822. The type species was designated in 1838 as the velvet scoter by Thomas Campbell Eyton. The genus name combines the Ancient Greek ''melas'' meaning "black" and ''netta'' meaning "duck". The genus contains six species: A fossil species, '' Melanitta kirbori'', is known from the Early Pleistocene of Crimea. The presumed fossil "scoter" ''Melanitta ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
