Sebright
The Sebright ( IPA: ) is a British breed of bantam chicken. It is a true bantam – a miniature bird with no corresponding large version – and is one of the oldest recorded British bantam breeds. It is named after Sir John Saunders Sebright, who created it as an ornamental breed by selective breeding in the early nineteenth century.Hobson, Jeremy and Lewis, Cecilia. ''Choosing & Raising Chickens: The complete guide to breeds and welfare''. David and Charles publishing. London. 2009. p 85. The first poultry breed to have its own specialist club for enthusiasts, Sebrights were admitted to poultry exhibition standards not long after their establishment. Today, they are among the most popular of bantam breeds. Despite their popularity, Sebrights are often difficult to breed, and the inheritance of certain unique characteristics the breed carries has been studied scientifically. As a largely ornamental chicken, they lay tiny, white eggs and are not kept for meat production. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir John Sebright, 7th Baronet
Sir John Saunders Sebright, 7th Baronet, (23 May 1767 – 15 April 1846), of Besford, Worcestershire, and Beechwood Park, Hertfordshire, was an English politician and agricultural innovator. Life Born on 23 May 1767 in Sackville Street, St. James's, he was the eldest son of Sir John Sebright, 6th Baronet, by Sarah, daughter of Edward Knight, of Wolverley, Worcestershire. His father died in March 1794. The seventh baronet served for a short time in the Foot Guards and was attached to the staff of Lord Amherst. He was elected M.P. for Hertfordshire on 11 May 1807, and continued to represent the county till the end of the first reformed parliament. He was appointed High Sheriff of Hertfordshire for 1797–98. He commanded the Western Battalion, Hertfordshire Local Militia, when it was raised at St Albans in 1808. Parliamentarian Sebright disclaimed connection with a party, but generally acted with the more advanced Whigs. He was a strong advocate of economy in administratio ...

Hen-feathered
Hen feathering in cocks is the occurrence of a genetically conditioned character in domestic fowl ('' Gallus gallus domesticus''). Males with this condition develop a female-type plumage, although otherwise look and respond as virile males. Hen-feathering in cocks is one of the typical characteristics of the Sebright Bantam, a breed established circa 1810, in accordance with the intentions of its creator, Sir John Saunders Sebright. Sexual dimorphism in plumage is very common in birds, particularly within Phasianidae where males are bigger and have brighter and more colorful plumage than females among other morphological differences. Cocks with hen-feathering Males of most chicken breeds distinguish from their females in having longer, sharp and more scalloped feathers in neck, hackle, saddle and wing bows. But in some breeds, like the fancy breeds Sebright and Campine and some game breeds like Pettai Madhirione can see males that have a plumage completely similar in al ...

Hertfordshire (UK Parliament Constituency)
Hertfordshire was a county constituency covering the county of Hertfordshire in England. It returned two Knights of the Shire to the House of Commons of England until 1707, then to the House of Commons of Great Britain until 1800, and to the House of Commons of the Parliament of the United Kingdom from 1800 until 1832. The Reform Act 1832 gave the county a third seat with effect from the 1832 general election. Elections were held using the bloc vote system, when contested. However, even after the 1832 reforms, contested elections were the exception: of the 17 elections from 1832 to 1880, 9 were uncontested, including the 1880 general election. In such cases all the nominated candidates were returned without a vote. History The constituency consisted of the historic county of Hertfordshire. (Although Hertfordshire contained two boroughs, Hertford and St Albans, each of which elected two MPs in its own right, these were not excluded from the county constituency, and own ...

List Of Chicken Breeds
There are hundreds of chicken breeds in existence. Domesticated for thousands of years, distinguishable breeds of chicken have been present since the combined factors of geographical isolation and selection for desired characteristics created regional types with distinct physical and behavioral traits passed on to their offspring. The physical traits used to distinguish chicken breeds are size, plumage color, comb type, skin color, number of toes, amount of feathering, egg color, and place of origin. They are also roughly divided by primary use, whether for eggs, meat, or ornamental purposes, and with some considered to be dual-purpose. In the 21st century, chickens are frequently bred according to predetermined breed standards set down by governing organizations. The first of such standards was the British Poultry Standard, which is still in publication today. Other standards include the Standard of Perfection, the Australian Poultry Standard, and the standard of the Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nankin (chicken)
The Nankin Bantam or Nankin is a British bantam breed of chicken. It is a true bantam, a naturally small breed with no large counterpart from which it was miniaturised. It is of South-east Asian origin, and is among the oldest bantam breeds. It is a yellowish buff colour, and the name is thought to derive from the colour of nankeen cotton from China. History The Nankin is thought to be one of the oldest true bantam breeds, originating somewhere in Southeast Asia. Though they first became widespread in the West only in the 18th century, there is evidence for their presence in England going back to the 16th century. As a bantam long present in the UK especially, the Nankin contributed to the formation of many other bantams more common today, such as the Sebright. Nankin are listed as 'Critical' on the endangered chicken breeds list of the Livestock Conservancy. They are very rarely found in the USA. The number of Nankins declined in the West after the mid 19th century, along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bantam (chicken)
A bantam is any small variety of fowl, usually of chicken or 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 true bantam chicken is naturally small and has no large counterpart. Etymology The word ''bantam'' derives from the name of the 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''. See also * List of chicken breeds * American Bantam Association The American Bantam Association is a poultry fancy association for breeders of bantam poultry. It publishes the ''Bantam Standard'', with detailed descriptions of all the bantam breeds and varieties that it recognizes; in most – but not all � ... * Call duck - bantam breed of duck originally bred ...

Correspondence Of Charles Darwin
The British naturalist Charles Darwin corresponded with his extended family and with an extraordinarily wide range of people from all over the world. The letters, over 15,000 in all, provide many insights on issues ranging from the origins of key scientific concepts, to religious and philosophical discussions which have continued to the present day. The letters also illuminate many aspects of Darwin and his biography: the development of his ideas; insights into character and health; and private opinions on controversial issues. His letters to the Harvard botanist Asa Gray, for example, show his opinions on slavery and the American Civil War. Darwin relied upon correspondence for much of his scientific work, and also used letters to marshal support for his ideas amongst friends and colleagues. The historian of science Janet Browne has argued that Darwin's ability to correspond daily played a crucial role in the development of his theory and his ability to garner support for it f ...

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature. Genetic studies have poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Observations
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echin ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individuals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On The Origin Of Species
''On the Origin of Species'' (or, more completely, ''On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life''),The book's full original title was ''On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life''. In the 1872 sixth edition, "On" was omitted, so the full title is ''The origin of species by means of natural selection, or the preservation of favoured races in the struggle for life.'' This edition is usually known as ''The Origin of Species.'' The 6th is Darwin's final edition; there were minor modifications in the text of certain subsequent issues. See Freeman, R. B. In Van Wyhe, John, ed.
