Chestnut (colour)
Chestnut or castaneous is a colour, a medium reddish shade of brown (displayed right), and is named after the nut of the chestnut tree. An alternate name for the colour is badious. Indian red is a similar but separate and distinct colour from ''chestnut''. Chestnut is also a very dark tan that almost appears brown. Etymology The name ''chestnut'' derives from the color of the nut of the chestnut tree. The first recorded use of ''chestnut'' as a color term in English was in 1555. The color maroon is also named after the chestnut (via French ''marron''). Variations of chestnut Deep chestnut Deep chestnut is the color called ''chestnut'' in Crayola crayons. This colour was also produced in a special limited edition in which it was called Vermont maple syrup. At the request of educators worried that children (mistakenly) believed the name represented the skin colour of Native Americans, Crayola changed the name of their crayon colour "Indian Red", originally formul ...

Colour
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Bird Colours
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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hair Color
Human hair color is the pigmentation of human hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more melanin is present, the color of the hair is darker; if less melanin is present, the hair is lighter. The tone of the hair is dependent on the ratio of black or brown eumelanin to yellow or red pheomelanin. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Some hair colors are associated with some ethnic groups due to observed higher frequency of particular hair color within their geographical region, e.g. straight dark hair amongst East Asians, a large variety of dark, fair, curly, wavy and bushy hair amongst Europeans, curly, dark, and uniquely helical hair with Africans, whilst gray, white or "silver" hair is often associated with age and wisdom.

Brown Hair
Brown hair, also referred to as brunet (male) or brunette (female), is the second most common human hair color, after black hair. It varies from light brown to a medium dark hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin. Brown hair is common among populations in the Western world, especially among those from Northwestern Europe, Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone,Brazil, Colombia, Costa Rica, Puerto Rico and the United States, and also some populations in the Middle East where it transitions smoothly into black hair.Frost, Peter"Why Do Europeans Have So Many Hair and Eye Colors?"(summarizing Frost, P. 2006.

Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chestnut (coat)
Chestnut is a hair coat color of horses consisting of a reddish-to-brown coat with a mane and tail the same or lighter in color than the coat. Chestnut is characterized by the absolute absence of true black hairs. It is one of the most common horse coat colors, seen in almost every breed of horse. Chestnut is a very common coat color but the wide range of shades can cause confusion. The lightest chestnuts may be mistaken for palominos, while the darkest shades can be so dark they appear black. Chestnuts have dark brown eyes and black skin, and typically are some shade of red or reddish brown. The mane, tail, and legs may be lighter or darker than the body coat, but unlike the bay they are never truly black. Like any other color of horse, chestnuts may have pink skin with white hair where there are white markings, and if such white markings include one or both eyes, the eyes may be blue. Chestnut foals may be born with pinkish skin, which darkens shortly afterwards. Chestnu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bongo (antelope)
The bongo (''Tragelaphus eurycerus'') is a herbivorous, mostly nocturnal forest ungulate. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes and long slightly spiralled horns. They are the only tragelaphid in which both sexes have horns. They have a complex social interaction and are found in African dense forest mosaics. Native to Africa, they are the third-largest antelope in the world. The western or lowland bongo, ''T. e. eurycerus'', faces an ongoing population decline, and the IUCN Antelope Specialist Group considers it to be Near Threatened on the conservation status scale. The eastern or mountain bongo, ''T. e. isaaci'', of Kenya, has a coat even more vibrant than that of ''T. e. eurycerus''. The mountain bongo is only found in the wild in a few mountain regions of central Kenya. This bongo is classified by the IUCN Antelope Specialist Group as Critically Endangered, with fewer individuals in the wild than in c ...

Chestnut-backed Chickadee
The chestnut-backed chickadee (''Poecile rufescens''), formerly ''Parus rufescens'', is a small passerine bird in the tit family, Paridae. It is found in the Pacific Northwest of the United States and western Canada, from southern Alaska to southwestern California. It is a permanent resident within its range, with some seasonal movements as feeding flocks move short distances in search of food. They usually move to lower elevations in the same area upon onset of winter and move back up to higher elevations in late summer. Chickadees are able to use nocturnal hypothermia to regulate energy expenditure, allowing them to survive harsh winters where other bird species not utilizing thermal regulation would not be able to. Some estimates put the energy conserved while using nocturnal hypothermia all the way up to 32%. It is a small chickadee, long with a weight of . The head is dark blackish-brown with white cheeks, the mantle is bright rufous-brown, the wing feathers are dark gray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parus RufescensDU1N028CA
''Parus'' is a genus of Old World birds in the tit family. It was formerly a large genus containing most of the 50 odd species in the family Paridae. The genus was split into several resurrected genera following the publication of a detailed molecular phylogenetic analysis in 2013. The genus name, ''Parus'', is the Latin for "tit". Taxonomy The genus ''Parus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is Latin for "tit". Of the 12 species included in the genus by Linnaeus, the type species was designated as the great tit (''Parus major'') by George Robert Gray in 1840. Species The genus now contains the following species: Fossil record *''Parus robustus'' (Pliocene of Csarnota, Hungary) Kessler, E. 2013. Neogene songbirds (Aves, Passeriformes) from Hungary. – Hantkeniana, Budapest, 2013, 8: 37-149. *''Parus parvulus'' (Pliocene of Csarnota, Hungary) *''Parus medius'' (Pliocene of Berem ...
