White-browed Tapaculo
The white-browed tapaculo (''Scytalopus superciliaris'') is a species of bird in the family Rhinocryptidae. It is found in northwestern Argentina. Taxonomy and systematics The white-browed tapaculo has at times been considered a subspecies of Magellanic tapaculo (''Scytalopus magellanicus''). It and Zimmer's tapaculo (''S. zimmeri'') form a superspecies.Krabbe, N. and T. S. Schulenberg (2020). White-browed Tapaculo (''Scytalopus superciliaris''), version 1.0.

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. Cabanis was born in Berlin to an old Huguenot family who had moved from France. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, returning in 1841 with a large natural history collection. He was assistant and later director of the Natural History Museum of Berlin (which was at the time the Berlin University Museum), taking over from Martin Lichtenstein. He founded the ''Journal für Ornithologie'' in 1853, editing it for the next forty-one years, when he was succeeded by his son-in-law Anton Reichenow. He died in Friedrichshagen. A number of birds are named after him, including Cabanis's bunting ''Emberiza cabanisi'', Cabanis's spinetail ''Synallaxis cabanisi'', Azure-rumped tanager The azure-rumped tanager or Cabanis's tanager (''Poecilostreptus cabanisi'') is a species of bird in the family Thraupidae.

Bird
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 further evolved for swimming. B ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards the ...

Cloaca
In animal anatomy, a cloaca ( ), plural cloacae ( or ), is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles and birds, and a few mammals ( monotremes, tenrecs, golden moles, and marsupial moles), have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory openings with analogous purpose in some invertebrates are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulation, commonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jujuy Province
Jujuy is a province of Argentina, located in the extreme northwest of the country, at the borders with Chile and Bolivia. The only neighboring Argentine province is Salta to the east and south. Geography There are three main areas in Jujuy: *The Altiplano, a plateau high with peaks of , covers most of the province. *The Río Grande of Jujuy cuts through the Quebrada de Humahuaca canyon, of heights between . *To the southeast, the sierras descends to the Gran Chaco region. The vast difference in height and climate produces desert areas such as the Salinas Grandes salt mines and subtropical Yungas jungle. The terrain of the province is mainly arid and semi-desertic across the different areas, except for the ''El Ramal'' valley of the San Francisco River. Temperature difference between day and night is wider in higher lands, and precipitation is scarce outside the temperate area of the San Francisco River. The Grande River and the San Francisco River flow to the Bermejo River. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Rioja Province, Argentina
La Rioja () is a province of Argentina located in the west of the country. The landscape of the province consist of a series of arid to semi-arid mountain ranges and agricultural valleys in between. It is in one of these valleys that the capital of the province, the city of la La Rioja, lies. Neighboring provinces are from the north clockwise Catamarca, Córdoba, San Luis and San Juan. The dinosaur '' Riojasaurus'' is named after the province. History Petroglyphs created by early indigenous peoples at the Talampaya National Park are dated around 10,000 years BC. Succeeding cultures of indigenous peoples developed here. The Diaguita, Capayan and the Olongasta peoples inhabited the territory of present-day La Rioja Province at the time of encounter with the Spanish colonists in the 16th century. Juan Ramírez de Velazco founded ''Todos Los Santos de la Nueva Rioja'' in 1591 under the government of Tucumán of the Viceroyalty of Peru. In 1630 the Calchaquí people revolted ...

Salta Province
Salta () is a province of Argentina, located in the northwest of the country. Neighboring provinces are from the east clockwise Formosa, Chaco, Santiago del Estero, Tucumán and Catamarca. It also surrounds Jujuy. To the north it borders Bolivia and Paraguay and to the west lies Chile. History Before the Spanish conquest, numerous native peoples (now called Diaguitas and Calchaquíes) lived in the valleys of what is now Salta Province; they formed many different tribes, the Quilmes and Humahuacas among them, which all shared the Cacán language. The Atacamas lived in the Puna, and the Wichís (Matacos), in the Chaco region. The first conquistador to venture into the area was Diego de Almagro in 1535; he was followed by Diego de Rojas. Hernando de Lerma founded San Felipe de Lerma in 1582, following orders of the viceroy Francisco de Toledo, Count of Oropesa; the name of the city was soon changed to "San Felipe de Salta". By 1650, the city had around five hundred inhabitan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alnus
Alders are trees comprising the genus ''Alnus'' in the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. Description With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (''Betula'', another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The largest species are red alder (''A. rubra'') on the west coast of North America, and black alder (''A. glutinosa''), native to ...

Polylepis
''Polylepis'' is a genus comprising 28 recognised shrub and tree species, that are endemic to the mid- and high-elevation regions of the tropical Andes. This group is unique in the rose family in that it is predominantly wind-pollinated. They are usually gnarled in shape, but in certain areas some trees are 15–20 m tall and have 2 m-thick trunks. The foliage is evergreen, with dense small leaves, and often having large amounts of dead twigs hanging down from the underside of the canopy. The name ''Polylepis'' is, in fact, derived from the Greek words poly (many) plus letis (layers), referring to the shredding, multi-layered bark that is common to all species of the genus. The bark is thick and rough and densely layered for protection against low temperatures. Some species of ''Polylepis'' form woodlands growing well above normal tree line within grass and scrub associations at elevations over 5000 m; which makes ''Polylepis'' appear to be the highest naturally occurring arbor ...
