Shade (Silverwing Character)
The Silverwing Book Series is a series of novels by Kenneth Oppel about the adventures of a young bat. All four books, published between 1997 and 2007, are commonly assigned in the curriculum of upper elementary and middle school grades in Canada, and in some parts of the United States. Summary Prologue: The Great War The great war between the birds and the beasts happened approximately 65 million years after the extinction of the dinosaurs for dominance over the land and sky. The bats, however, seeing themselves as neither birds nor beasts, remained neutral throughout the conflict. Finally a compromise was reached; the birds would control the sky, while the beasts would claim the land. However, because the bats refused to take sides, they were banished from being allowed to fly during the day—not even allowed to so much as look at the sun—ever again; only emerging at night. The war is based on Aesop's Fables called "The Birds, the Beasts and the Bat." Sun Freedom (Silverw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silverwing (novel)
''Silverwing'' is a best-selling children's novel, written by Kenneth Oppel, first published in 1997 by HarperCollins. It tells the story of a colony of silverwing bats. The tone and artistic ambition of this series of bestsellers has been compared to the classic animal novel ''Watership Down''.

Mercury (mythology)
Mercury (; la, Mercurius ) is a major god in Roman religion and mythology, being one of the 12 Dii Consentes within the ancient Roman pantheon. He is the god of financial gain, commerce, eloquence, messages, communication (including divination), travelers, boundaries, luck, trickery, and thieves; he also serves as the guide of souls to the underworld. In Roman mythology, he was considered to be either the son of Maia, one of the seven daughters of the Titan Atlas, and Jupiter, or of Caelus and Dies. In his earliest forms, he appears to have been related to the Etruscan deity Turms; both gods share characteristics with the Greek god Hermes. He is often depicted holding the caduceus in his left hand. Similar to his Greek equivalent Hermes, he was awarded a magic wand by Apollo, which later turned into the caduceus, the staff with intertwined snakes. Etymology The name "Mercury" is possibly related to the Latin words ' ("merchandise"; cf. ''merchant'', ''commerce'', etc ...

Eumops
''Eumops'' (mastiff bats or bonneted bats) is a genus of bat Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most ...s in the family Molossidae. A total of 17 species of this genus have been described. The name "Eumops" comes from the Greek prefix "Eu-", meaning "good" or "true," and the Malayan word "mops," which means bat.Best, T. L., Kiser, W. M., & Freeman, P. W. (1996). Eumops perotis. Systematics Species The following are the seventeen species of ''Eumops''. ''Eumops chimaera'' is the most recently described species of this genus, having been first described in 2016. ''E. wilsoni'' was described first in 2009 by Baker and colleagues. *'' E. auripendulus'' (Shaw, 1800) — black bonneted bat (Shaw's mastiff bat) *'' E. bonariensis'' (Peters, 1874) — dwarf bonneted bat ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Albino
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and pink or blue eyes. Individuals with the condition are referred to as albino. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV radiation and their lack of camouflage to avoid predators. It is a common misconception that all albino animals have characteristic pink or red eyes (resulting from the lack of pigment in the iris allowing the blood vessels of the retina to be visible), however this is not the case for some forms of albinism. Familiar albino animals include in-bred strains of laboratory animals (rats, mice and rabbits), but populations of naturally occurring albino animals exist in the wil ...

Phoenix (mythology)
The phoenix is an immortal bird associated with Greek mythology (with analogs in many cultures) that cyclically regenerates or is otherwise born again. Associated with the sun, a phoenix obtains new life by rising from the ashes of its predecessor. Some legends say it dies in a show of flames and combustion, others that it simply dies and decomposes before being born again. In the ''Motif-Index of Folk-Literature'', a tool used by folklore studies, folklorists, the phoenix is classified as motif B32.Thompson. (2001: 581). The origin of the phoenix has been attributed to Ancient Egypt by Herodotus and later 19th-century scholars, but other scholars think the Egyptian texts may have been influenced by classical folklore. Over time the phoenix motif spread and gained a variety of new associations; Herodotus, Lucan, Pliny the Elder, Pope Clement I, Lactantius, Ovid, and Isidore of Seville are among those who have contributed to the retelling and transmission of the phoenix motif.

Suicide
Suicide is the act of intentionally causing one's own death. Mental disorders (including depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders), physical disorders (such as chronic fatigue syndrome), and substance abuse (including alcoholism and the use of and withdrawal from benzodiazepines) are risk factors. Some suicides are impulsive acts due to stress (such as from financial or academic difficulties), relationship problems (such as breakups or divorces), or harassment and bullying. Those who have previously attempted suicide are at a higher risk for future attempts. Effective suicide prevention efforts include limiting access to methods of suicide such as firearms, drugs, and poisons; treating mental disorders and substance abuse; careful media reporting about suicide; and improving economic conditions. Although crisis hotlines are common resources, their effectiveness has not been well studied. The most commonly adopted metho ...

Hallucinogenic
Hallucinogens are a large, diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes. Most hallucinogens can be categorized as either being psychedelics, dissociatives, or deliriants. However, certain hallucinogens such as Fly agaric as well as other gabaergic hallucinogenics are more often considered to technically be hypnotics, therefore indicating another separate subcategory of drugs which can substantially alter visual perception. Etymology The word ''hallucinogen'' is derived from the word ''hallucination''. The term ''hallucinate'' dates back to around 1595–1605, and is derived from the Latin ''hallūcinātus'', the past participle of ''(h)allūcināri'', meaning "to wander in the mind." Characteristics Leo Hollister gave five criteria for classifying a drug as hallucinogenic.Glennon RA. Classical drugs: an introductory overview. In Lin GC and Gl ...

Spectral Bat
The spectral bat (''Vampyrum spectrum''), also called the great false vampire bat or Linnaeus's false vampire bat, is a large, carnivorous leaf-nosed bat found in Mexico, Central America, and South America. It is the only member of the genus ''Vampyrum''; its closest living relative is the big-eared woolly bat. It is the largest bat species in the New World, as well as the largest carnivorous bat: its wingspan is . It has a robust skull and teeth, with which it delivers a powerful bite to kill its prey. Birds are frequent prey items, though it may also consume rodents, insects, and other bats. Unlike the majority of bat species, it is monogamous. Colonies consist of an adult male and female and their offspring. The adult male will bring food back to the roost to provision the adult female and their offspring. Colonies generally roost in tree hollows, though individuals may roost in caves. Due to habitat destruction and its low population density, it is listed as a near-threaten ...

Camazotz
In the Late Post-Classic Maya mythology of the Popol Vuh, Camazotz ( from Mayan ) (alternate spellings Cama-Zotz, Sotz, Zotz) is a bat spirit at the service of the lords of the underworld. Camazotz means "death bat" in the Kʼicheʼ language. In Mesoamerica generally, the bat is often associated with night, death, and sacrifice. Etymology Camazotz is formed from the Kʼicheʼ words ''kame'', meaning "death", and ''sotz, meaning "bat". Mythology In the Popol Vuh, Camazotz are the bat-like spirits encountered by the Maya Hero Twins Hunahpu and Xbalanque during their trials in the underworld of Xibalba. The twins had to spend the night in the House of Bats, where they squeezed themselves into their own blowguns in order to defend themselves from the circling bats. Hunahpu stuck his head out of his blowgun to see if the sun had risen and Camazotz immediately snatched off his head and carried it to the ballcourt to be hung up as the ball to be used by the gods in their next ballgame ...
