Nycticorax
''Nycticorax'' is a genus of night herons. The name ''Nycticorax'' means "night raven" and derives from the Ancient Greek νύκτος, ''nuktos'' "night" and κοραξ, ''korax'', "raven". It refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron. These are medium-sized herons which often are migratory in the colder parts of their ranges. Adults are short-necked, relatively short-legged and stout herons; the two extant species both have a black crown and a whitish belly, while the wings, chest, neck and auriculars are grey or rufous depending on the species. Young birds are brown, flecked with white and grey, and are quite similar to each other in the extant species. At least some of the extinct Mascarenes taxa appear to have retained this juvenile plumage in adult birds. Night herons nest in colonies on platforms of sticks in a group of trees, or on the ground in pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-crowned Night Heron (Nycticorax Nycticorax) RWD2
The black-crowned night heron (''Nycticorax nycticorax''), or black-capped night heron, commonly shortened to just night heron in Eurasia, is a medium-sized heron found throughout a large part of the world, including parts of Europe, Asia, and North and South America. In Australasia it is replaced by the closely related nankeen night heron, with which it has hybridized in the area of contact. Taxonomy The black-crowned night heron was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with herons, cranes and egrets in the genus '' Ardea'' and coined the binomial name ''Ardea nicticorax''. It is now placed in the genus ''Nycticorax'' that was introduced in 1817 by the English naturalist Thomas Forster for this species. The epithet ''nycticorax'' is from Ancient Greek and combines ''nux'', ''nuktos'' meaning "night" and ''korax'' meaning "raven". The word was used by authors such as Aristotle and Hesy ...

Gorsachius
''Gorsachius'' is a genus of Old World night herons typically found near water in forested regions. These are medium-sized herons which are migratory in the colder parts of their ranges, but otherwise resident. They are the least known, most strictly nocturnal, smallest and overall rarest night herons. Three of the four species are found in East, South and South-east Asia, while the last species, the white-backed night heron, is found in sub-Saharan Africa. The Japanese and Malayan night herons resemble each other, being relatively short-billed and overall brown with a dark line from the throat to the upper belly. The larger white-eared and white-backed night herons are darker, with distinctive white markings on the face and neck in the former, and an entirely black head in the latter. Their behavior, especially that of the white-eared night heron, is relatively poorly known compared to that of other night herons, but they nest alone or in small groups, and a clutch of two to f ...

Nyctanassa
''Nyctanassa'' is a genus of night herons from the Americas, especially (but not exclusively) warmer coastal regions. They were formerly included in the genus ''Nycticorax'', but today all major authorities recognize them as different. The name comes from Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic peri ... words for "night" and "lady" or "queen", referring to the yellow-crowned night heron's nocturnal activity and its beauty.

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and ''Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Conrad Gessner
Conrad Gessner (; la, Conradus Gesnerus 26 March 1516 – 13 December 1565) was a Swiss physician, naturalist, bibliographer, and philologist. Born into a poor family in Zürich, Switzerland, his father and teachers quickly realised his talents and supported him through university, where he studied classical languages, theology and medicine. He became Zürich's city physician, but was able to spend much of his time on collecting, research and writing. Gessner compiled monumental works on bibliography (''Bibliotheca universalis'' 1545–1549) and zoology (''Historia animalium'' 1551–1558) and was working on a major botanical text at the time of his death from plague at the age of 49. He is regarded as the father of modern scientific bibliography, zoology and botany. He was frequently the first to describe species of plants or animals in Europe, such as the tulip in 1559. A number of plants and animals have been named after him. Life Conrad Gessner was born on 26 March 1516, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesychius Of Miletus
Hesychius of Miletus ( el, Ἡσύχιος ὁ Μιλήσιος, translit=Hesychios o Milesios), Greek chronicler and biographer, surnamed Illustrius, son of an advocate, lived in Constantinople in the 6th century AD during the reign of Justinian. His writings contain more references to pagan Greek culture than Christianity, but his religion remains a matter of dispute among scholars. According to Photius (cod. 69) he was the author of three important works: #A ''Compendium of Universal History'' in six books, from Belus, the reputed founder of the Assyrian empire, to Anastasius I (d. 518). A considerable fragment has been preserved from the sixth book, a history of Byzantium from its earliest beginnings till the time of Constantine the Great. #A ''Biographical Dictionary of Learned Men'', arranged according to classes (poets, philosophers), the chief sources of which were the works of Aelius Dionysius and of Herennius Philo.

Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...
