Quiscalus Niger -Ciego De Avila Province, Cuba-8 (3)
The avian genus ''Quiscalus'' contains seven of the 11 species of grackles, gregarious passerine birds in the icterid family. They are native to North and South America. The genus was named and described by French ornithologist Louis Jean Pierre Vieillot in 1816. The type species was subsequently designated as the common grackle (''Quiscalus quiscula'') by English zoologist George Robert Gray in 1840. The genus name comes from the specific name ''Gracula quiscula'' coined by Swedish naturalist Carl Linnaeus for the common grackle. From where Linnaeus obtained the word is uncertain, but it may come from the Taíno word ''quisqueya'', meaning "mother of all lands", for the island of Hispaniola Hispaniola (, also ; es, La Española; Latin and french: Hispaniola; ht, Ispayola; tnq, Ayiti or Quisqueya) is an island in the Caribbean that is part of the Greater Antilles.

Common Grackle
The common grackle (''Quiscalus quiscula'') is a species of large icterid bird found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles can be found widely across North America east of the Rocky Mountains. Taxonomy The common grackle was first described in 1758 by Carl Linnaeus in the tenth edition of ''Systema Naturae'', as ''Gracula quiscula''. It was assigned to the genus ''Quiscalus'' by French ornithologist Louis Jean Pierre Vieillot in his 1816 ''Dictionnaire d'histoire naturelle''. Three subspecies are recognized: *the Florida grackle (''Q. q. quiscula'') (Linnaeus 1758), the nominate subspecies *the purple grackle (''Q. q. stonei'') (Chapman, 1935) *the bronzed grackle (''Q. q. versicolor'') (Vieillot, 1816) Descri ...

Boat-tailed Grackle
The boat-tailed grackle (''Quiscalus major'') is a passerine bird of the family Icteridae found as a permanent resident on the coasts of the Southeastern United States. Habitat The boat-tailed grackle is found in coastal saltwater marshes and, in Florida, also on inland waters. Boat-tailed grackles have established significant populations in several United States Gulf Coast cities and towns, where they can be found foraging in trash bins, dumpsters, and parking lots. Breeding The nest is a well-concealed cup in trees or shrubs near water; three to five eggs are laid. Description The male boat-tailed grackle is long and weighs . Adult males have entirely iridescent black plumage, a long dark bill, a pale yellowish or brown iris, and a long keel-shaped tail. The adult female is much smaller at long and a weight of . She is also distinguished by her shorter tail and tawny-brown coloration, which covers the body apart from the darker wings and tail. The wingspan in adult birds is . ...

Thirsty (8387794451)
Thirst is the craving for potable fluids, resulting in the basic instinct of animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids or an increase in the concentration of certain osmolites, such as sodium. If the water volume of the body falls below a certain threshold or the osmolite concentration becomes too high, structures in the brain detect changes in blood constituents and signal thirst. Continuous dehydration can cause acute and chronic diseases, but is most often associated with renal and neurological disorders. Excessive thirst, called polydipsia, along with excessive urination, known as polyuria, may be an indication of diabetes mellitus or diabetes insipidus. There are receptors and other systems in the body that detect a decreased volume or an increased osmolite concentration. Some sources distinguish "extracellular thirst" from "intracellular thirst", where extracellular thirst is thirst generated by decreased v ...

Toluca Valley
The Toluca Valley is a valley in central Mexico, just west of the Valley of Mexico (Mexico City), the old name was Matlatzinco. The valley runs north–south for about , surrounded by mountains, the most imposing of which is the Nevado de Toluca Volcano. It is one of the highest valleys in Mexico and for this reason has a relatively cold climate. Since the 1940s, there has been significant environmental degradation in the valley, with the loss of forests, soil erosion, falling water tables and water pollution due to growth in industry and population. In the pre-Hispanic period, it was a buffer region between the Aztec Empire and Purépecha Empire. From the Aztec period until the 19th century, it was part of the region controlled by Mexico City, but today it is the center of the State of Mexico, which has its capital in Toluca, the main city of the valley. Physical geography and climate The Toluca Valley is a broad highland valley located immediately west of the Valley of Mexico. I ...

Valley Of Mexico
The Valley of Mexico ( es, Valle de México) is a highlands plateau in central Mexico roughly coterminous with present-day Mexico City and the eastern half of the State of Mexico. Surrounded by mountains and volcanoes, the Valley of Mexico was a centre for several pre-Columbian civilizations, including Teotihuacan, the Toltec, and the Aztec. The ancient Aztec term ('Land Between the Waters') and the phrase Basin of Mexico are both used at times to refer to the Valley of Mexico. The Basin of Mexico became a well known site that epitomized the scene of early Classic Mesoamerican cultural development as well. The Valley of Mexico is located in the Trans-Mexican Volcanic Belt. The valley contains most of the Greater Mexico City, Mexico City Metropolitan Area, as well as parts of the State of Mexico, Hidalgo (state), Hidalgo, Tlaxcala, and Puebla. The Basin of Mexico covers approximately in the NNE-SSW direction with length to width dimensions of approximately to The Valley of ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slender-billed Grackle
The slender-billed grackle (''Quiscalus palustris'') was a species of grackle in the Icteridae (New World blackbirds) family of birds. The species was closely related to the western clade of the great-tailed grackle, from which it diverged quite recently, around 2,000 years ago. The slender-billed grackle was endemic to central Mexico, especially in the Valley of Mexico and the Toluca Valley. Early observations recorded by Franciscan friar Bernardino de Sahagún in the 16th-century manuscript '' General History of the Things of New Spain'' indicate that the species was found in cultivated areas and towns. Later records indicated that it might be a marsh specialist. The species became extinct Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ... around the turn of the 20th century. Hab ...

Great-tailed Grackle
The great-tailed grackle or Mexican grackle (''Quiscalus mexicanus'') is a medium-sized, highly social passerine bird native to North and South America. A member of the family Icteridae, it is one of 10 extant species of grackle and is closely related to the boat-tailed grackle and the extinct slender-billed grackle. In the southern United States, it is sometimes simply referred to as "blackbird" or (erroneously) "crow" due to its glossy black plumage, and similarly it is often called ("raven") in some parts of Mexico, although it is not a member of the crow genus ''Corvus'', nor even of the family Corvidae. Description Great-tailed grackles are medium-sized birds (larger than starlings and smaller than crows; -) with males weighing - and females between -, and both sexes have long tails. Wingspan ranges from 18.9-22.8 in (48-58 cm). Males are iridescent black with a purple-blue sheen on the feathers of the head and upper body, while females are brown with darker wings and ta ...
