Lesser Vasa Parrot
The lesser vasa parrot or black parrot (''Coracopsis nigra'') is a black coloured parrot Endemism, endemic to most of Madagascar. It is one of four species of vasa parrots, the others being the greater vasa parrot ''C. vasa'', the Seychelles black parrot (''C. barklyi''), and the Comoros black parrot (''C. sibilans''). The latter two were formerly considered conspecific with the lesser vasa parrot. Lesser vasa parrots inhabit the mangrove swamps and evergreen forests of Madagascar. They eat seeds, blossoms and fruit - especially berries and mangos. They build their bird nest, nests in tree hollows and go through courtship in February. During this time, the female may shed the feathers on her head giving it a yellowish tone. The male's beak may also turn white during this time. Taxonomy In 1743 the English naturalist George Edwards (naturalist), George Edwards included a picture and a description of the lesser vasa parrot in his ''A Natural History of Uncommon Birds''.

Anjajavy Forest
The Anjajavy's Protected Area is located on a peninsula of the town of Antonibe, in the district of Analalava and in the north-west region of Madagascar. It is part of the Sofia region of the independent province of Mahajanga and its position is between 47°13’ at 44°22’ of longitude east and 14°58 at 15°07’ of latitude south.. Anjajavy's Protected Area is an element of the Madagascar dry deciduous forests situated on the Indian Ocean of northwest Madagascar. The Anjajavy Forest surrounds the village of Anjajavy and provides a habitat for many rare and endangered species.Nick Garbutt, C. Michael Hogan, Hilton Hastings, Wendy Pollecutt, Tahiana Andriaharimalala, ''Anjajavy, the village and the forest'', Lumina Technologies, May 12, 2006 It covers roughly fifty square kilometres, and occupies a continuous portion of the peninsula upon which Anjajavy village lies.

Courtship
Courtship is the period wherein some couples get to know each other prior to a possible marriage. Courtship traditionally may begin after a betrothal and may conclude with the celebration of marriage. A courtship may be an informal and private matter between two people or may be a public affair, or a formal arrangement with family approval. Traditionally, in the case of a formal engagement, it is the role of a male to actively "court" or "woo" a female, thus encouraging her to understand him and her receptiveness to a marriage proposal. Duration The average duration of courtship varies considerably throughout the world. Furthermore, there is vast individual variation between couples. Courtship may be completely omitted, as in cases of some arranged marriages where the couple do not meet before the wedding. In the United Kingdom, a poll of 3,000 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'' ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Systema Naturae
' (originally in Latin written ' with the ligature æ) is one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, Linnaeus was first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ' or translated: "System of nature through the three kingdoms of nature, according to classes, orders, genera and species, with characters, differences, synonyms, places". The tenth edition of this book (1758) is considered the starting point of zoological nomenclature. In 1766–1768 Linnaeus published the much enhanced 12th edition, the last under his authorship. Another again enhanced work in the same style and titled "'" was published by Johann Friedrich Gmelin between 1788 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Lennox, 2nd Duke Of Richmond
Charles Lennox, 2nd Duke of Richmond, 2nd Duke of Lennox, 2nd Duke of Aubigny, (18 May 17018 August 1750) of Goodwood House near Chichester in Sussex, was a British nobleman and politician. He was the son of Charles Lennox, 1st Duke of Richmond, 1st Duke of Lennox, the youngest of the seven illegitimate sons of King Charles II. He was the most important of the early patrons of the game of cricket and did much to help its evolution from village cricket to first-class cricket. Early life Lennox was styled Earl of March from his birth in 1701 as heir to his father's dukedom. He also inherited his father's love of sports, particularly cricket. He had a serious accident at the age of 12 when he was thrown from a horse during a hunt, but he recovered and it did not deter him from horsemanship. March entered into an arranged marriage in December 1719 when he was still only 18 and his bride, Hon. Sarah Cadogan, was just 13, in order to use Sarah's large dowry to pay his considera ...

George Edwards (naturalist)
George Edwards (3 April 1694 – 23 July 1773) was an English naturalist and ornithologist, known as the "father of British ornithology". Edwards was born at West Ham, then in the county of Essex. In his early years, he travelled extensively through mainland Europe, studying natural history, and gained a reputation for his coloured drawings of animals, especially birds. He was appointed as beadle to the Royal College of Physicians in 1733. Over a period of 21 years, Edwards published seven volumes containing descriptions and hand-coloured etchings of birds. In a few cases, he depicted other animals. None of the species were native to the British Isles. The first four volumes were published between 1743 and 1751 with the title ''A Natural History of Uncommon Birds''. The three subsequent volumes were published between 1758 and 1764 with the title ''Gleanings Of Natural History''. The volumes contain a total of 362 hand-coloured etchings of which 317 depict birds. The etchings w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...

Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...
