Purple Martin
The purple martin (''Progne subis'') is a passerine bird in the swallow family Hirundinidae. It is the largest swallow in North America. Despite its name, the purple martin is not truly purple. The dark blackish-blue feathers have an iridescent sheen caused by the refraction of incident light giving them a bright blue to navy blue or deep purple appearance. In some light they may even appear green in color. Being migratory, their breeding range extends from central Alberta down through the eastern United States. Subspecies breed in Baja California, Arizona, and New Mexico. Most make a brief stopover in the Yucatán Peninsula or Cuba during pre-breeding migration to North America and during post-breeding migration before reaching their overwintering site in South America. They are known for their speed, agility, and their characteristic mix of rapid flapping and gliding flight pattern. When approaching their nesting site, they will dive from the sky at great speeds with their wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the Ancient Greece, ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the Cosmogony, origin and Cosmology#Metaphysical cosmology, nature of the world, the lives and activities of List of Greek mythological figures, deities, Greek hero cult, heroes, and List of Greek mythological creatures, mythological creatures, and the origins and significance of the ancient Greeks' own cult (religious practice), cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral tradition, oral-poetic tradition most likely by Minoan civilization, Minoan and Mycenaean Greece, Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its after ...

Caribbean Martin
The Caribbean martin or white-bellied martin (''Progne dominicensis'') is a large swallow. It has at various times been considered alternatively as a race of the purple martin, ''Progne subis''. Distribution It breeds throughout the Caribbean, except on Cuba and Isla de la Juventud, where it is replaced by the related Cuban martin (''P. cryptoleuca''). It is closely related to the aforementioned species, as well as the Sinaloa martin (''P. sinaloae'') to which it used to be considered conspecific. There are sight records from mainland Central and South America, and most birds appear to migrate to the South American mainland. A single bird was recorded in Key West, Florida, on May 9, 1895 (AOU 2000). Description Adult Caribbean martins are 18.5 cm in length, with a forked tail and relatively broad wings, and weigh 40 g. Adult males are a glossy blue-black with contrasting white lower underparts. Females and juveniles are duller than the male, with grey-brown bre ...

Sexually Dimorphic
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated d ...

William Brewster (ornithologist)
William Brewster (July 5, 1851 – July 11, 1919) was an American ornithologist. He co-founded the American Ornithologists' Union (AOU) and was an early naturalist and conservationist. Early life and education Childhood William Brewster was born on July 5, 1851, in South Reading (now Wakefield), Massachusetts, the youngest of four children born to John Brewster, a successful Boston banker, and Rebecca Parker (Noyes). The couple settled in Cambridge, Massachusetts in 1845. Brewster's sister and older brothers died in early childhood, inspiring Longfellow, a close neighbor, to write the poem ''The Open Window''. Brewster attended Cambridge public schools, Washington Grammar School and Cambridge High School, taking a preparatory course to enter Harvard. He suffered eyesight problems as a youth and into adulthood. He was often unable to read or study, sometimes for extended periods. During his last year of high school, he was unable to read so his mother read his lessons to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigidius Figulus
Publius Nigidius Figulus (c. 98 – 45 BC) was a scholar of the Late Roman Republic and one of the praetors for 58 BC. He was a friend of Cicero, to whom he gave his support at the time of the Catilinarian conspiracy. Nigidius sided with the Optimates in the civil war between Julius Caesar and Pompeius Magnus. Among his contemporaries, Nigidius's reputation for learning was second only to that of Varro. Even in his own time, his works were regarded as often abstruse, perhaps because of their esoteric Pythagoreanism, into which Nigidius incorporated Stoic elements. Jerome calls him ''Pythagoricus et magus'', a "Pythagorean and mage," and in the medieval and Renaissance tradition he is portrayed as a magician, diviner, or occultist. His vast works survive only in fragments preserved by other authors. Political career By 63 BC, Nigidius had been admitted to the Senate. He may have been aedile in 60 BC, when Cicero mentions that Nigidius was in a position to cite (''compellare'') a ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Thrace
Thrace (; el, Θράκη, Thráki; bg, Тракия, Trakiya; tr, Trakya) or Thrake is a geographical and historical region in Southeast Europe, now split among Bulgaria, Greece, and Turkey, which is bounded by the Balkan Mountains to the north, the Aegean Sea to the south, and the Black Sea to the east. It comprises southeastern Bulgaria (Northern Thrace), northeastern Greece (Western Thrace), and the European part of Turkey ( East Thrace). The region's boundaries are based on that of the Roman Province of Thrace; the lands inhabited by the ancient Thracians extended in the north to modern-day Northern Bulgaria and Romania and to the west into the region of Macedonia. Etymology The word ''Thrace'' was first used by the Greeks when referring to the Thracian tribes, from ancient Greek Thrake (Θρᾴκη), descending from ''Thrāix'' (Θρᾷξ). It referred originally to the Thracians, an ancient people inhabiting Southeast Europe. The name ''Europe'' first referred to ...
