Black-winged Lovebird
The black-winged lovebird (''Agapornis taranta'') also known as Abyssinian lovebird is a mainly green bird of the parrot family. At about 16.5 cm (6.5 inches) long, it is the largest of the lovebird genus, a group of small parrots. The adult male is easily identified by its red forehead, and the adult female by its all-green head. They are native to Eritrea and Ethiopia, and they are uncommon as pets. Description The black-winged lovebird, with a length of about 16–16.5 cm (6.25–6.5 inches), is the largest of all the lovebirds. It is sexually dimorphic, as are the red-headed lovebird and grey-headed lovebird of the lovebird genus. The dimorphism becomes apparent in juvenile birds after their first molt at about eight or nine months of age. Both the male and female black-winged lovebird are mostly green, and only the adult male black-winged lovebird has a red forehead and a ring of red feathers around its eyes. The tail is black tipped and feathers below the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Smith-Stanley, 13th Earl Of Derby
Edward Smith-Stanley, 13th Earl of Derby (21 April 1775 – 30 June 1851), KG, of Knowsley Hall in Lancashire (styled Lord Stanley from 1776 to 1832, known as Baron Stanley of Bickerstaffe from 1832-4), was a politician, peer, landowner, builder, farmer, art collector and naturalist.

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Lovebirds
Lovebird is the common name for the genus ''Agapornis'', a small group of parrots in the Old World parrot family Psittaculidae. Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar. Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and the long periods which paired birds spend sitting together. Lovebirds live in small flocks and eat fruit, vegetables, grasses, and seeds. Black-winged lovebirds also eat insects and figs, and black-collared lovebirds have a special dietary requirement for native figs, making them difficult to keep in captivity. Some species are kept as pets, and several coloured mutations have been selectively bred in aviculture. The average lifespan is 20 to 30 years. Description Lovebirds are in length, up to 24 cm in wingspan with 9 cm for a single wing and in weight. They are among the smallest parrots, cha ...

Henry Salt (Egyptologist)
Henry Salt (14 June 178030 October 1827) was an English artist, traveller, collector of antiquities, diplomat, and Egyptologist. Biography Early life Salt, the son of Thomas Salt who was a physician and Alice ''née'' Butt, was born in Lichfield on 14 June 1780. He was the youngest of eight children and went to school in Lichfield, Market Bosworth, and then in Birmingham under where his brother John Butt Salt taught. He took an early interest in portrait painting. While in Lichfield, he studied under a watercolour artist, John Glover, and in 1789, he went to London where he first studied under Joseph Farington and later under John Hoppner. After a time, he gave up portrait painting, having failed to build up a reputation. Early travels Salt found a position with the English nobleman George Annesley, Viscount Valentia, travelling as his secretary and draughtsman, recommended by Thomas Simon Butt. They started on an eastern tour in June 1802, sailing on the British East India ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Museum
World Museum is a large museum in Liverpool, England which has extensive collections covering archaeology, ethnology and the natural and physical sciences. Special attractions include the Natural History Centre and a planetarium. Entry to the museum is free. The museum is part of National Museums Liverpool. History The museum was originally started as the Derby Museum as it comprised the 13th Earl of Derby's natural history collection. It opened in 1851, sharing two rooms on Duke Street with a library. However, the museum proved extremely popular and a new, purpose-built building was required. Land for the new building, on a street then known as Shaw's Brow (now William Brown Street), opposite St George's Hall, was donated by local MP and Merchant William Brown, as was much of the funding for the building which would be known as the William Brown Library and Museum. Around 400,000 people attended the opening of the new building in 1860. Reports detailing the museum's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Museums Liverpool
National Museums Liverpool, formerly National Museums and Galleries on Merseyside, comprises several museums and art galleries in and around Liverpool, England. All the museums and galleries in the group have free admission. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport and an exempt charity under English law. In the 1980s, local politics in Liverpool was under the control of the Militant group of the Labour Party. In 1986, Liverpool's Militant councillors discussed closing down the city's museums and selling off their contents, in particular their art collections. To prevent this from happening the Conservative government nationalised all of Liverpool's museums under the ''Merseyside Museums and Galleries Order 1986'' which created a new national trustee body ''National Museums and Galleries on Merseyside''.Suzanne MacLeod, ''Museum Architecture: A New Biography'', p31.

Psittacus
''Psittacus'' is a genus of African grey parrots in the subfamily Psittacinae. It contains the two species: the grey parrot (''Psittacus erithacus'') and the Timneh parrot (''Psittacus timneh''). For many years, the grey parrot and Timneh parrot were classified as subspecies; the former as the nominate, the latter as ''P. e. timneh''. However, in 2012 the taxa were recognized as separate species by BirdLife International on the basis of genetic, morphological, plumage and vocal differences. These parrots are found in the primary and secondary rainforest of West and Central Africa. They are among the most intelligent birds in the world. They feed primarily on palm nuts, seeds, fruits, and leafy matter, but have also been observed eating snails. Their inclination and ability to mimic speech and other sounds have made them popular pets. Taxonomy The genus ''Psittacus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fledge
Fledging is the stage in a flying animal's life between hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Network defines the phenophase (or life cycle stage) of fledged young for birds as "One or more young are seen recently departed from the nest. This includes young incapable of sustained fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nest
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and several social insec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment and management of chronic conditions. Dietar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
