Cayuga Duck
The Cayuga is an American breed of domestic duck. It was introduced to the Finger Lakes region of New York State in about 1840, and is named for the Cayuga people of that area. Until the last years of the nineteenth century it was the principal duck reared for meat in the United States. In the twenty-first century it is kept mainly for ornament. History The origins of the Cayuga are obscure. A much-repeated theory that it descends not from the mallard like almost all domestic ducks, but from ''Anas rubripes'', the American black duck, remains unsubstantiated and unverified by any scientific evidence. Unlike ''Anas rubripes'', the Cayuga is a true black in color; this color is the result of a genetic mutation fairly common in breeds derived from ''Anas platyrhynchos''. The Cayuga has other characteristics compatible with derivation from the Mallard; in particular, it shows the typical curled "drake feather" in the tail, while ''Anas rubripes'' does not. In about 1840, one Jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Livestock Breeds Conservancy
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, the Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of nine and a 19-member board of directors, the organization has an operating budget of almost half a million dollars. The Livestock Conservancy maintains a conservation priority list that divides endangered breeds of horses, asses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic 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 of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duck Breeds Originating In The United States
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poultry Show
A poultry show is a specific subset of a livestock show that involves the exhibition and competition of exhibition poultry, which may include chickens, domestic ducks, domestic geese, domestic guineafowl and domestic turkey. Domestic pigeon are also exhibited but not universally considered poultry. As well as being independent events, they are also sometimes held in conjunction with agricultural shows. Preparation Significant effort is put into exhibiting poultry. Birds are trained for the cages used at shows, and washed and manicured in preparation for an event. History The first poultry show in the United Kingdom was in 1845 in London. The exhibition of poultry was promoted as an alternative to cock fighting in the United Kingdom following the banning of such activities in 1849. The first poultry standard in the world was produced in 1865, the British Poultry Standard. The height of the poultry showing in the United Kingdom was during the late 19th and early 20th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Pekin
The Pekin or White Pekin is an American breed of domestic duck, raised primarily for meat. It derives from birds brought to the United States from China in the nineteenth century, and is now bred in many parts of the world. It is often known as the American Pekin to distinguish it from the German Pekin, a distinct and separate breed which derives from the same Chinese stock but has different breeding. Many of these ducks were reared on Long Island, New York, in the late nineteenth and early twentieth centuries, from which the breed derived its name Long Island Duck. History The mallard was domesticated in China some 3000 years ago, and possibly much earlier. Force-feeding of ducks is documented from the tenth century, under the Five Dynasties. The Chinese were sophisticated breeders of ducks; among several breeds they created was one named ''shi-chin-ya-tze'', which roughly translates to "ten-pound duck", from which the American Pekin derives. In 1872, James E. Palmer of S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cayuga County
Cayuga County is a county in the U.S. state of New York. As of the 2020 census, the population was 76,248. Its county seat and largest city is Auburn. The county was named for the Cayuga people, one of the Indian tribes in the Iroquois Confederation. Cayuga County comprises the Auburn, NY Micropolitan Statistical Area, which is also included in the Syracuse-Auburn, NY Combined Statistical Area. History When counties were established in the Province of New York in 1683, the present Cayuga County was part of Albany County. This was an enormous county, including the northern part of the present state of New York and all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766, by the creation of Cumberland County, and further on March 16, 1770, by the creation of Gloucester County, both containing territory now in Vermont. On March 12, 1772, what was left of Albany County was split into three parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
