Nankeen Kestrel
The nankeen kestrel (''Falco cenchroides''), also known as the Australian kestrel, is a raptor native to Australia and New Guinea. It is one of the smallest falcons, and unlike many, does not rely on speed to catch its prey. Instead, it simply perches in an exposed position, but it also has a distinctive technique of hovering over crop and grasslands. Taxonomy The nankeen kestrel is a species of the genus ''Falco'', allied to a subgenus ''Tinnunculus''. They were first described by Nicholas Vigors and Thomas Horsfield in 1827. Further descriptions — regarded as synonyms for the species — were published: ''Cerchneis immaculata'' Brehm, 1845; the later name ''Cerchneis unicolor'' by Alexander Milligan was published in ''Emu'' in 1904; and that author's name appearing in the assignment to a subspecies, ''Cerchneis cenchroides milligani'', published by Gregory Mathews in 1912. The generic name is Late Latin ''falco'' 'falcon' (from ''falx'' ''falcis'', 'sickle') and the speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicholas Aylward Vigors
Nicholas Aylward Vigors (1785 – 26 October 1840) was an Ireland, Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Early life Vigors was born at Old Leighlin, County Carlow on 1785 as first son from Capt. Nicholas Aylward Vigors which served in 29th (Worcestershire) Regiment of Foot, 29th (Worcestershire) Regiment and, his first wife, Catherine Vigors, daughter of Solomon Richards of Solsborough. He matriculated at Trinity College, Oxford on November 1803 before he was admitted at Lincoln's Inn on November 1806. Without completing his studies, he served in the army during the Peninsular War from 1809 to 1811 and wounded in Battle of Barrosa, Battle of Barossa on 5 March 1811. Though, he haven't completed his studies yet, he still published "An inquiry into the nature and extent of poetick licence" in London at 1810. He then returned to Oxford to continued his studies and achieved his Bachelor of Arts on 1817 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christmas Island
Christmas Island, officially the Territory of Christmas Island, is an Australian external territory comprising the island of the same name. It is located in the Indian Ocean, around south of Java and Sumatra and around north-west of the closest point on the Australian mainland. It lies northwest of Perth and south of Singapore. It has an area of . Christmas Island had a population of 1,692 residents , the majority living in settlements on the northern edge of the island. The main settlement is Flying Fish Cove. Historically, Asian Australians of Chinese, Malay, and Indian descent formed the majority of the population. Today, around two-thirds of the island's population is estimated to have Straits Chinese origin (though just 22.2% of the population declared a Chinese ancestry in 2021), with significant numbers of Malays and European Australians and smaller numbers of Straits Indians and Eurasians. Several languages are in use, including English, Malay, and various ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles
Reptiles, as most commonly defined are the animals in the Class (biology), class Reptilia ( ), a paraphyletic grouping comprising all sauropsid, sauropsids except birds. Living reptiles comprise turtles, crocodilians, Squamata, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean taxonomy, Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern Cladistics, cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile Order (biology), orders, historically combined with that of modern amphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nankeen Kestrel Waverton Edit
Nankeen (also called Nankeen cloth) is a kind of pale yellowish cloth originally made in Nanking (modern Nanjing), China from a yellow variety of cotton, but subsequently manufactured from ordinary cotton that is then dyed.''Oxford English Dictionary'' The term blue nankeen describes hand-printed fabric of artistic refinement and primitive simplicity, which originated on the Silk Road over three thousand years ago. Hand-carved stencils, originally made from wood but now from heavy paper, are prepared and a mix of soybean flour and slaked lime is applied through the openings of the stencil onto the 100% cotton fabric. When dry, the fabric is then dipped numerous times into the large tubs containing the indigo dye. After the desired color is achieved and the fabric has dried, the paste is scraped off, revealing the white patterns on the blue cloth. The fabric is then washed, dried, and ironed before fabrication. Derived uses Nankeen also refers to: *Trousers made of nankeen (sin ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Bergmann's Rule
Bergmann's rule is an ecogeographical rule that states that within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions. Bergmann's rule only describes the overall size of the animals, but does not include body parts like Allen's rule does. Although originally formulated in relation to species within a genus, it has often been recast in relation to populations within a species. It is also often cast in relation to latitude. It is possible that the rule also applies to some plants, such as '' Rapicactus''. The rule is named after nineteenth century German biologist Carl Bergmann, who described the pattern in 1847, although he was not the first to notice it. Bergmann's rule is most often applied to mammals and birds which are endotherms, but some researchers have also found evidence for the rule in studies of ectothermic species, such as the ant ''L ...

Gloger's Rule
Gloger's rule is an ecogeographical rule which states that within a species of endotherms, more heavily pigmented forms tend to be found in more humid environments, e.g. near the equator. It was named after the zoologist Constantin Wilhelm Lambert Gloger, who first remarked upon this phenomenon in 1833 in a review of covariation of climate and avian plumage color. Erwin Stresemann later noted that the idea had been expressed even earlier by Peter Simon Pallas in ''Zoographia Rosso-Asiatica'' (1811). Gloger found that birds in more humid habitats tended to be darker than their relatives from regions with higher aridity. Over 90% of 52 North American bird species studies conform to this rule. One explanation of Gloger's rule in the case of birds appears to be the increased resistance of dark feathers to feather- or hair-degrading bacteria such as ''Bacillus licheniformis''. Feathers in humid environments have a greater bacterial load, and humid environments are more suitable for mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Falcon
The brown falcon (''Falco berigora'') is a relatively large falcon native to Australia and New Guinea. A number of plumage morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing coverts. Dark morph birds have predominantly dark under parts, although some light streaking is common. Pale morph birds have white underparts that are varyingly streaked with brown, sometimes heavily so. Pale individuals may also have prominently white under tail coverts and these may be diagnostic. A distinctive aspect of their behaviour is shown in the breeding season when Brown Falcons make a loud, high pitched, cackle call (like a laying hen) and screeching while in flight. The species name ''berigora'' has Aboriginal origins. Description Adults are usually long. They are found in light and dark forms and a variety of intermediates. Animals typically have red-brown heads with narrow black streaks with a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elanid Kite
An elanine kite is any of several small, lightly-built raptors with long, pointed wings. Some authorities list the group as a formal subfamily, Elaninae. As a subfamily there are six species in three genera with two of these genera being monotypic. Two other species have at times been included with the group, but genetic research has shown them to belong to different subfamilies. Elanine kites have a near-worldwide distribution, with two endemic species found in the Americas, two in Australia, and one in Africa, while the black-winged kite is found over a vast range from Europe and Africa in the west to Southeast Asia in the east. Species Current Elaninae Previously in Elaninae * Genus ''Machaerhamphus'' or ''Macheiramphus'' (subfamily Harpiinae) ** Bat hawk, ''M. alcinus'' – Paleotropics (Africa, south Asia through to New Guinea) * Genus ''Elanoides'' (subfamily Perninae) ** Swallow-tailed kite, ''Elanoides forficatus'' – Americas Description ''Elanus'' species are pri ...
