Magnificent Bird-of-paradise
The magnificent bird-of-paradise (''Cicinnurus magnificus'') is a species of bird-of-paradise. The magnificent bird-of-paradise is evaluated as Least Concern on the IUCN Red List of Threatened Species. They are listed on Appendix II of CITES. Etymology The generic name ''Cicinnurus'' means "curled tail" and its specific name ''magnificus'' means magnificent or splendid. The species was formerly listed in the genus ''Diphyllodes'', which means "Double leaf-like", referring to its "leaf-like" tail. Taxonomy The Magnificent bird-of-paradise is included in the same genus as the King and Wilson's Birds-of-paradise, though it's more closely related to the latter. The genus ''Cicinnurus'' forms a clade with the genera ''Paradisaea'' and '' Paradisornis'', and the other closest genus is ''Astrapia,'' though it is not included in the clade. Subspecies This species has three subspecies: *''C. m. magnificus''( Forster, 1781) (Northwestern New Guinea) *''C. m. chrysopterus'' (Elliot, 1873 ...

Thomas Pennant
Thomas Pennant (14 June Old Style, OS 172616 December 1798) was a Welsh natural history, naturalist, traveller, writer and antiquarian. He was born and lived his whole life at his family estate, Downing Hall near Whitford, Flintshire, in Wales. As a naturalist he had a great curiosity, observing the geography, geology, plants, animals, birds, reptiles, amphibians and fish around him and recording what he saw and heard about. He wrote acclaimed books including ''British Zoology'', the ''History of Quadrupeds'', ''Arctic Zoology'' and ''Indian Zoology'' although he never travelled further afield than continental Europe. He knew and maintained correspondence with many of the scientific figures of his day. His books influenced the writings of Samuel Johnson. As an antiquarian, he amassed a considerable collection of art and other works, largely selected for their scientific interest. Many of these works are now housed at the National Library of Wales. As a traveller he visited Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

King Of Holland's Bird-of-paradise
The King of Holland's bird of paradise, also known as King William III's bird of paradise or the exquisite little king, is a bird in the family Paradisaeidae that is a hybrid between a magnificent bird of paradise and king bird of paradise. History At least 26 adult male specimens of this hybrid exist in various collections, including the American Museum of Natural History and the Manchester Museum, coming mainly from north coastal New Guinea or unknown localities. It was described as a new species by Adolf Bernard Meyer in 1875 and diagnosed as a hybrid by Jacques Berlioz Jacques Berlioz (9 December 1891, Paris – 21 December 1975) was a French zoologist and ornithologist, specializing in hummingbirds. He was a grand-nephew of composer Hector Berlioz (1803–1869). Berlioz was born in Paris, where the family h ... in 1927.Frith & Beehler (1998), p.507.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Bird-of-paradise
The king bird-of-paradise (''Cicinnurus regius'') is a passerine bird of the Paradisaeidae (bird-of-paradise) family. It is considered by the IOC checklist to be the only member of the genus ''Cicinnurus'', although the genus ''Diphyllodes'' is closely related and is subsumed under ''Cicinnurus'' by many other authorities. The king bird-of-paradise is a common and wide-ranging species, distributed throughout lowland forests of New Guinea and western satellite islands. Some populations range quite high into the hills and lower mountains, and these are poorly known as yet. The first captive breeding of this species was by Sten Bergman of Sweden in 1958. He was awarded a commemorative medal by the Foreign Bird League to mark this achievement. Taxonomy The king bird-of-paradise was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Paradisaea regius''. The type locality is the Aru Islands. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not ...

Female
Female (Venus symbol, symbol: ♀) is the sex of an organism that produces the large non-motile ovum, ova (egg cells), the type of gamete (sex cell) that fuses with the Sperm, male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, Sex-determination system, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced Secondary sex characteristic, secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sickle
A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting, or reaping, grain crops or cutting succulent forage chiefly for feeding livestock, either freshly cut or dried as hay. Falx was a synonym but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge such as a scythe. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives.

Turquoise (color)
Turquoise ( ) is a blue-green color, based on the mineral of the same name. The word ''turquoise'' dates to the 17th century and is derived from the French , meaning 'Turkish', because the mineral was first brought to Europe through Turkey from mines in the historical Khorasan province of Iran (Persia) and Afghanistan. The first recorded use of ''turquoise'' as a color name in English was in 1573. The X11 color named turquoise is displayed on the right. Turquoise gemstones Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminium, with the chemical formula Cu Al6( P O4)4(O H)8·4 H2O. It is rare and valuable in finer grades and has been prized as a gem and ornamental stone for thousands of years owing to its unique hue. In many cultures of the Old and New Worlds, this gemstone has been esteemed for thousands of years as a holy stone, a bringer of good fortune or a talisman. The oldest evidence for this claim was found in ancien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lime (color)
Lime is a color that is a shade of yellow-green, so named because it is a representation of the color of the citrus fruit called limes. It is the color that is in between the web color chartreuse and yellow on the color wheel.Maerz and Paul ''A Dictionary of Color'' New York: 1930 McGraw-Hill; The index refers to Plate 20 Color Sample J1 as ''Lime Green''; this color is shown on Plate 20 as being halfway between ''yellow-green'' (the old name for the color that is now called chartreuse green) and ''yellow'' on the color wheel. Alternate names for this color included yellow-green, lemon-lime, lime green, or bitter lime. Lime (traditional lime green) The first recorded use of ''lime green'' as a color name in English was in 1890. Lime (color hex code #BFFF00) is a pure spectral color at approximately 564 nanometers on the visible spectrum when plotted on the CIE chromaticity diagram.

Iridescence
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. It is a kind of structural coloration that is due to wave interference of light in microstructures or thin films. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
