Crested (duck Breed)
The Crested is a breed of domestic duck. It was probably brought to Europe from the East Indies by Dutch ships. It has its appearance because it is heterozygous for a genetic mutation causing a deformity of the skull. History The Crested probably originates in the East Indies, with subsequent development in Holland. Crested ducks are seen in seventeenth-century paintings such as those of Melchior d'Hondecoeter and Jan Steen. In the United States the breed was described by D.J. Browne in 1853. The white Crested was added to the American Standard of Perfection in 1874; the black variant was added in 1977. The Crested was recognised in the United Kingdom in 1910. A bantam version of the breed, the Crested Miniature, was bred by John Hall and Roy Sutcliffe in the United Kingdom in the late twentieth century; it was recognised in 1997. Characteristics Apart from the crest, the Crested is an ordinary-looking duck of medium size. It may be of any colour, although in the United ...

Camden, Maine
Camden is a resort town in Knox County, Maine. The population was 5,232 at the 2020 census. The population of the town more than triples during the summer months, due to tourists and summer residents. Camden is a summer colony in the Mid-Coast region of Maine. Similar to Bar Harbor, Nantucket and North Haven, Camden is well known for its summer community of wealthy Northeasterners, mostly from Boston, New York City, and Philadelphia. History The Penobscot Nation have lived in the area for thousands of years. They called it Megunticook, meaning "great swells of the sea", a reference to the silhouette of the Camden Hills (more visibly seen on a bright night). Although part of the Waldo Patent, Europeans did not attempt to colonize it until after the French and Indian War, around 1771–1772. They were led by James Richards, who built a home at the mouth of the Megunticook River. Others soon followed, squatting on Penobscot land and attempting to farm the broken and often ...

Domestic Duck
The domestic duck or domestic mallard (''Anas platyrhynchos domesticus'') is a subspecies of mallard that has been domesticated by humans and raised for meat, eggs, and down feathers. A few are also kept for show, as pets, or for their ornamental value. Almost all varieties of domesticated ducks, apart from the domestic Muscovy duck (''Cairina moschata''), are descended from the mallard. Domestication Whole-genome sequencing indicate that domestic ducks originate from a single domestication event of mallards during the Neolithic, followed by rapid selection for lineages favoring meat or egg production. They were likely domesticated in Southeast Asia (most likely Southern China) by the rice paddy-farming ancestors of modern Southeast Asians. The date of domestication is unknown due to the scarcity of archaeological records. They spread outwards from the region, first being mentioned in Han Chinese written records in central China by around 500 BC. Duck farming for both meat an ...

Two Ducks Of Falls Park 2017
2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures. Evolution Arabic digit The digit used in the modern Western world to represent the number 2 traces its roots back to the Indic Brahmic script, where "2" was written as two horizontal lines. The modern Chinese and Japanese languages (and Korean Hanja) still use this method. The Gupta script rotated the two lines 45 degrees, making them diagonal. The top line was sometimes also shortened and had its bottom end curve towards the center of the bottom line. In the Nagari script, the top line was written more like a curve connecting to the bottom line. In the Arabic Ghubar writing, the bottom line was completely vertical, and the digit looked like a dotless closing question mark. Restoring the bottom line to its original horizontal ...

East Indies
The East Indies (or simply the Indies), is a term used in historical narratives of the Age of Discovery. The Indies refers to various lands in the East or the Eastern hemisphere, particularly the islands and mainlands found in and around the Indian Ocean by Portuguese explorers, soon after the Cape route was discovered. Nowadays, this term is broadly used to refer to the Malay Archipelago, which today comprises the Philippine Archipelago, Indonesian Archipelago, Malaysian Borneo, and New Guinea. Historically, the term was used in the Age of Discovery to refer to the coasts of the landmasses comprising the Indian subcontinent and the Indochinese Peninsula along with the Malay Archipelago. Overview During the era of European colonization, territories of the Spanish Empire in Asia were known as the Spanish East Indies for 333 years before the American conquest. Dutch occupied colonies in the area were known for about 300 years as the Dutch East Indies till Indonesian indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterozygous
Zygosity (the noun, zygote, is from the Greek "yoked," from "yoke") () is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism. Most eukaryotes have two matching sets of chromosomes; that is, they are diploid. Diploid organisms have the same loci on each of their two sets of homologous chromosomes except that the sequences at these loci may differ between the two chromosomes in a matching pair and that a few chromosomes may be mismatched as part of a chromosomal sex-determination system. If both alleles of a diploid organism are the same, the organism is homozygous at that locus. If they are different, the organism is heterozygous at that locus. If one allele is missing, it is hemizygous, and, if both alleles are missing, it is nullizygous. The DNA sequence of a gene often varies from one individual to another. These gene variants are called alleles. While some gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutation is the ultimate source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melchior D'Hondecoeter
Melchior d'Hondecoeter (; 1636 – 3 April 1695), Dutch animalier painter, was born in Utrecht and died in Amsterdam. After the start of his career, he painted virtually exclusively bird subjects, usually exotic or game, in park-like landscapes. Hondecoeter's paintings featured geese (brent goose, Egyptian goose and red-breasted goose), fieldfares, partridges, pigeons, ducks, northern cardinal, magpies and peacocks, but also African grey crowned cranes, Asian sarus cranes, Indonesian yellow-crested cockatoos, an Indonesian purple-naped lory and grey-headed lovebirds from Madagascar.

Jan Steen
Jan Havickszoon Steen (c. 1626 – buried 3 February 1679) was a Dutch Golden Age painter, one of the leading genre painters of the 17th century. His works are known for their psychological insight, sense of humour and abundance of colour. Life Steen was born in Leiden, a town in Southern Holland, where his well-to-do, Catholic family were brewers who ran the tavern ''The Red Halbert'' for two generations. Steen's father even leased him a brewery of his own in Delft from the years 1654 until 1657. He was the eldest of eight or more children. Like his even more famous contemporary Rembrandt van Rijn, Jan Steen attended the Latin school and became a student in Leiden. Though no official records of Steen's artistic training are preserved, contemporary sources tell us he received his painterly education from three men, Nicolaes Knupfer (1603–1660), a German painter of historical and figurative scenes in Utrecht, Adriaen van Ostade, and Jan van Goyen, who would later become ...

American Standard Of Perfection
The ''American Standard of Perfection'' is the official breed standard for the poultry fancy in North America. First published in 1874 by the American Poultry Association, the ''Standard of Perfection'' (commonly referred to as "the ''Standard''") classifies and describes the standard physical appearance, coloring and temperament for all recognized breeds of poultry, including chickens, ducks, turkeys, and geese. The current edition was published in 2015. Use The ''Standard'' is used by American Poultry Association judges at sanctioned poultry shows to judge poultry, and by those who participate in the competitive showing of selectively bred birds that conform to the standard, which led to the term "standard bred" poultry. History The first edition of the book listed 41 breeds, and today's versions have nearly 60. There are 19 classes of poultry recognized by the American Poultry Association. Eleven of these classes are devoted to chickens, of which six are classes of large bree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bantam (poultry)
A bantam is any small variety of fowl, usually of chicken or domestic duck, duck. Most large chicken breeds and several breeds of duck have a bantam counterpart, which is much smaller than the standard-sized fowl, but otherwise similar in most or all respects. A List of true bantam chicken breeds, true bantam chicken is naturally small and has no large counterpart. Etymology The word ''bantam'' derives from the name of the Banten (town), seaport city of Bantam in western Java, Indonesia. European sailors restocking on live fowl for sea journeys found the small native breeds of chicken in Southeast Asia to be useful, and any such small poultry came to be known as a ''bantam''.
