Oology
Oology (or oölogy) is a branch of ornithology studying bird eggs, nests and breeding behaviour. The word is derived from the Greek ''oion'', meaning egg. Oology can also refer to the hobby of collecting wild birds' eggs, sometimes called egg collecting, birdnesting or egging, which is now illegal in many jurisdictions. History As a science Oology became increasingly popular in Britain and the United States during the 1800s. Observing birds from afar was difficult because high quality binoculars were not readily available. Thus it was often more practical to shoot the birds or collect their eggs. While the collection of the eggs of wild birds by amateurs was considered a respectable scientific pursuit in the 19th century and early 20th century, from the mid 20th century onwards it was increasingly regarded as being a hobby rather than a scientific discipline. In the 1960s, the naturalist Derek Ratcliffe compared peregrine falcon eggs from historical collections with more rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithology
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

Egg Collection Part Of AGW
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective eggshell, shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jourdain Society
The Jourdain Society is or was a controversial society based in the United Kingdom, its aims being ‘the advancement of the science of oology’, the collection and study of intact birds' eggs. Established in 1922 as the British Oological Association, it changed its name in 1946 in memory of distinguished ornithologist and oologist Reverend Francis Jourdain (1865–1940). The society was a social gathering that held regular dinners, established as an elitist club, which did not admit women and professional dealers. Egg-collecting is the removal of intact, unhatched eggs from a birds' nest, followed by drilling out the contents to keep the egg intact. It was considered a respectable leisure pursuit in the nineteenth and early twentieth century, at a time when conservation, study and hunting were not seen as opposed activities. However the activity became extremely controversial after conservationists concluded that the taking of rare birds' eggs was a major factor in their extinct ...

Bird Eggs
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The album ...

Francis Charles Robert Jourdain
The Reverend Francis Charles Robert Jourdain M.A., F.Z.S., M.B.O.U. (4 March 1865 – 27 February 1940), was a notable British amateur ornithologist and oologist. He was primarily known for his extensive research into the breeding biology of the birds of the Palaearctic region. He also had interests in the food of British birds and their geographical distribution and strongly encouraged detailed and accurate record keeping in local ornithology. Known for his temper, he came be known by the nickname ''Pastor Pugnax''. He was a founder of the British Oological Association, which changed its name after his death to the Jourdain Society in his memory. Early years Jourdain was born in Ashbourne, Derbyshire, the eldest son of Rev. Francis Jourdain, vicar of Ashbourne-cum-Mapleton. He matriculated at Magdalen College, Oxford in 1883, he graduated B.A. in 1887. Ordained in 1890, he had two curacies in Suffolk, and then was appointed vicar of Clifton-by-Ashbourne in 1894.

Charles Bendire
Major Charles Emil Bendire (April 27, 1836 – February 4, 1897) was a United States Army soldier and noted ornithologist and oologist. The Bendire's thrasher is named for him. Early life Born Karl Emil Bender at König im Odenwald in the Grand Duchy of Hesse-Darmstadt, he was the eldest of six children. Bender was home schooled until the age of twelve, after which he attended five years at a theological school at Passy, near Paris. Karl left school suddenly and returned home, and on the advice of a friend he and his brother Wilhelm Bender left for New York in 1853. Upon arrival they found that the New World did not meet their expectations. Wilhelm Bender soon sailed for home, but was lost overboard at sea. Army career After his brother's departure, Bender enlisted in the United States Army at the age of eighteen on June 10, 1854, changing his name to Charles Bendire, dropping his middle name altogether. Although Bendire would later start using his middle initial again in cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
