Cattle Tyrant (Machetornis Rixosa) On Capybara
The cattle tyrant (''Machetornis rixosa'') is a species of bird in the tyrant flycatcher family Tyrannidae. In Brazil, it is called suiriri-cavaleiro. It is the only member of the genus ''Machetornis''. The relationships of this species and genus to other genera in the tyrant flycatchers are uncertain. It resembles ''Tyrannus'' flycatchers, but this may be the result of convergent evolution, convergence. Subspecies and distribution The genus name was given to the species by George Robert Gray and is derived from the Ancient Greek for fighter and for bird, a reference to its pugnacious behaviour and habit of dispossessing other species of their nests. The specific name comes from the Latin meaning quarrelsome, again referring to the behaviour and temperament of the species.Mobley, J. (2017). Cattle Tyrant (''Machetornis rixosa'').

Cleaning Symbiosis
Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment. Cleaning is often performed for beauty, aesthetic, hygiene, hygienic, Function (engineering), functional, safety, or environmental protection purposes. Cleaning occurs in many different contexts, and uses many different methods. Several occupations are devoted to cleaning. Contexts Cleaning occurs in various commercial, domestic, personal, and environmental contexts, which differ in scale and requirements. * Commercial cleaning, in business or other commercial settings ** Terminal cleaning, in healthcare settings * Housekeeping, including spring cleaning * Hygiene, including personal grooming * Environmental remediation, the removal of pollution or contaminants from the natural environment Methods Cleaning is broadly achieved through mechanical action and/or chemical processes (usually solvation); many methods rely on a combination of m ...

Birds Described In 1819
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furthe ...

Tyrannidae
The tyrant flycatchers (Tyrannidae) comprise a Family (biology), family of passerine birds which is found virtually throughout North America, North and South America. It is the world's largest family of birds, with more than 400 species, and is the most Species richness, diverse avian family in every country in the Americas, except for the United States and Canada. The members vary greatly in shape, patterns, size, and colors. Some tyrant flycatchers may superficially resemble the Old World flycatchers, which they are named after but are not closely related to. The Tyrannidae is a member of suborder Tyranni (suboscines), a group that lacks the sophisticated vocal capabilities of most other songbirds.del Hoyo, J. Elliott, A. & Christie, D. (editors). (2004) ''Handbook of the Birds of the World. Volume 9: Cotingas to Pipits and Wagtails''. Lynx Edicions.

Costanera Sur Ecological Reserve
Buenos Aires Ecological Reserve, ''Reserva Ecológica de Buenos Aires'', also known as Costanera Sur Ecological Reserve, ''Reserva Ecológica Costanera Sur'', is a tract of low land on the Río de la Plata riverbank located on the east side of the district of Puerto Madero in Buenos Aires CBD, Argentina. History After opening in 1918, the Municipal Riverside resort was witness to the splendour and decadence of the “Costanera Sur” promenade. On foot, by car or tram, thousands of porteños came to this place in search of fresh air in summer afternoons, or to bathe in the river, smartly clad in their one piece bathing costume and carrying a towel. In accordance to the 1923 Regulations, men and women bathed in the river separated by the long pier.Buenos Aires Ecological Reserve: History < ...

Capybara
The capybara or greater capybara (''Hydrochoerus hydrochaeris'') is the largest living rodent, native to South America. It is a member of the genus '' Hydrochoerus''. The only other extant member is the lesser capybara (''Hydrochoerus isthmius''). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the nutria. The capybara inhabits savannas and dense forests, and lives near bodies of water. It is a highly social species and can be found in groups as large as one hundred individuals, but usually live in groups of 10–20 individuals. The capybara is hunted for its meat and hide and also for grease from its thick fatty skin. Etymology Its common name is derived from Tupi , a complex agglutination of (leaf) + (slender) + (eat) + (a suffix for agent nouns), meaning "one who eats slender leaves", or "grass-eater". The genus name, ''hydrochoerus'', comes from Greek (' "water") and (' "pig, hog") an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is found in Brazil, Bolivia, Argentina, Ecuador, Paraguay, and Peru. Taxonomy and systematics The rufous-fronted thornbird's taxonomy is unsettled.

Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Louis Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the , the first two volumes of which were published in France beginning in 1807. Vieillot returned to France for the last time in 1798, whe ...
