Purple Finch
The purple finch (''Haemorhous purpureus'') is a bird in the finch family, Fringillidae. Taxonomy This species and the other "American rosefinches" were formerly included with the rosefinches of Eurasia in the genus ''Carpodacus''; however, the three North American species are not closely related to the rosefinches of the Old World, and have thus been moved to the genus ''Haemorhous'' by most taxonomic authorities. It is included in the finch family, Fringillidae, which is made up of passerine birds found in the northern hemisphere, Africa, and South America. The purple finch was originally described by Johann Friedrich Gmelin in 1789. There are two subspecies of the purple finch, ''H. p. purpureus'' and ''H. p. californicus''. ''H. p. californicus'' was identified by Spencer F. Baird in 1858. It differs from the nominate subspecies in that it has a longer tail and shorter wings. The plumage of both males and females is darker, and the coloration of the females is more greenis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

House Finch
The house finch (''Haemorhous mexicanus'') is a bird in the finch family Fringillidae. It is native to western North America and has been introduced to the eastern half of the continent and Hawaii. This species and the other two American rosefinches are placed in the genus ''Haemorhous''. Description This is a moderate-sized finch. Adult birds are long, with a wingspan of . Body mass can vary from , with an average weight of . Among standard measurements, the wing chord is , the tail is , the culmen is and the tarsus is . Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers. Breast and belly feathers may be streaked; the flanks usually are. In most cases, adult males' heads, necks and shoulders are reddish. This color sometimes extends to the belly and down the back, between the wings. Male coloration varies in intensity with the seasons and is derived from the berries and fr ...

Taxa Named By Johann Friedrich Gmelin
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1789
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. Bird ...

Haemorhous
The American rosefinches that form the genus ''Haemorhous'', are a group of passerine birds in the finch family Fringillidae. As the name implies ("haemo" means "blood" in Greek), various shades of red are characteristic plumage colors of this group. They are found throughout the North American continent. The genus is not closely related to the ''Carpodacus'' rosefinches that are found in Europe and Asia. Systematics There have been a number of rosefinch radiations. One of the first to split off were the ancestors of the North American species and diverged in the Middle Miocene The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and mea ... (about 14–12 mya) from the proto-rosefinches.

Salvia Hispanica
''Salvia hispanica'', commonly known as chia (), is a species of flowering plant in the mint family, Lamiaceae, native to central and southern Mexico and Guatemala. It is considered a pseudocereal, cultivated for its edible, hydrophilic chia seed, grown and commonly used as food in several countries of western South America, western Mexico, and the southwestern United States. Etymology The word "chia" is derived from the Nahuatl word ''chian'', meaning oily. ''S. hispanica'' is one of two plants known as "chia", the other being ''Salvia columbariae'', which is sometimes called "golden chia". Description Chia is an annual herb growing up to tall, with opposite leaves that are long and wide. Its flowers are purple or white and are produced in numerous clusters in a spike at the end of each stem.Anderson, A.J.O. and Dibble, C.E.

Purple Finch On A Fir Branch
Purple is any of a variety of colors with hue between red and blue. In the RGB color model used in computer and television screens, purples are produced by mixing red and blue light. In the RYB color model historically used by painters, purples are created with a combination of red and blue pigments. In the CMYK color model used in printing, purples are made by combining magenta pigment with either cyan pigment, black pigment, or both. Purple has long been associated with royalty, originally because Tyrian purple dye, made from the mucus secretion of a species of snail, was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor and aristocracy. According to contemporary surveys in Europe and the United States, purple is the color most oft ...

House Sparrow
The house sparrow (''Passer domesticus'') is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, and deserts away from human development. It feeds mostly on the seeds of grains and weeds, but it is an opportunistic eater and commonly eats insects and many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
