Buff-browed Foliage-gleaner
The buff-browed foliage-gleaner (''Syndactyla rufosuperciliata'') is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Brazil, Ecuador, Paraguay, Peru, and Uruguay. Taxonomy and systematics The buff-browed foliage-gleaner's taxonomy is unsettled.

Frédéric De Lafresnaye
Baron Nöel Frédéric Armand André de Lafresnaye (24 July 1783 – 14 July 1861) was a French ornithologist and collector. Lafresnaye was born into an aristocratic family at Chateau de La Fresnaye in Falaise, Calvados, Falaise, Normandy. He took an early interest in natural history, particularly entomology. It was only after acquiring a collection of European birds that he turned his attention to ornithology. Lafresnaye described a number of new bird species, some with Alcide d'Orbigny. He accumulated a collection of over 8,000 bird skins at his home. After his death the collection was purchased by the American collector Henry Bryant (naturalist), Henry Bryant and donated to the Boston Society of Natural History, Boston Natural History Society. It was transferred to the Museum of Comparative Zoology in 1914. Lafresnaye's piculet, Lafresnaye's woodcreeper and Lafresnaye's vanga are avian species that bear his name.

Clements Taxonomy
''The Clements Checklist of Birds of the World'' is a book by Jim Clements which presents a list of the bird species of the world. The most recent printed version is the sixth edition (2007), but has been updated yearly, the last version in 2022, and is published by Cornell University Press. Previous editions were published by the author's own imprint, Ibis Publishing. The Cornell Lab of Ornithology has provided annual updates since then, usually in August, and the most recent version is available online in several formats. These updates reflect the ongoing changes to bird taxonomy based on published research. ''Clements'' is the official list used by the American Birding Association for birds globally. eBird eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project ... also uses the ''Clem ... [...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 ...

Cordillera Del Cóndor
The Cordillera del Cóndor (Condor mountain range) is a mountain range in the eastern Andes that is shared by and part of the international border between Ecuador and Peru. The range extends approximately 150 km north to south and its maximum elevation reaches approximately 2,900m. The Río Santiago and Cenepa River flow along its eastern slopes on the Peruvian side. For over 160 years, the area of the border was in dispute, and sparked armed conflicts between the two countries in 1941, 1981 and 1995. After the border conflict of 1995, the two countries began diplomatic negotiations, resulting in the 1998 peace treaty that established the exact location of the international border. The Cordillera del Condor is an area of great interest to biology, possibly having the richest flora in any area of the same size on the South American continent, and is considered by Conservation International to be one of the most important biodiversity areas on the planet.

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal, inferior n ...

Covert Feather
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...

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 ...

Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furnariid
Ovenbirds or furnariids are a large family of small suboscine passerine birds found from Mexico and Central to southern South America. They form the family Furnariidae. This is a large family containing around 315 species and 70 genera. The ovenbird (''Seiurus aurocapilla''), which breeds in North America, is not a furnariid – rather it is a distantly related bird of the wood warbler family, Parulidae. The ovenbirds are a diverse group of insectivores which get their name from the elaborate, vaguely "oven-like" clay nests built by the horneros, although most other ovenbirds build stick nests or nest in tunnels or clefts in rock.Remsen, J. V., Jr. 2003. Family Furnariidae (ovenbirds). Pages 162–357 in J. del Hoyo, A. Elliott and D. A. Christie eds. Handbook of the birds of the world, Vol. 8, broadbills to tapaculos. Lynx Edicions, Barcelona. The Spanish word for "oven" ''(horno)'' gives the horneros their name. Furnariid nests are always constructed with a cover, and up to six ...

Atlantic Forest
The Atlantic Forest ( pt, Mata Atlântica) is a South American forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where the region is known as Selva Misionera. The Atlantic Forest has ecoregions within the following biome categories: seasonal moist and dry broad-leaf tropical forests, tropical and subtropical grasslands, savannas, and shrublands, and mangrove forests. The Atlantic Forest is characterized by a high biodiversity and endemism. It was the first environment that the Portuguese colonists encountered over 500 years ago, when it was thought to have had an area of , and stretching an unknown distance inland, making it, back then, the second largest rainforest on the planet, only behind the Amazon rainforest. Over 85% of the original area has been deforested, threatening many plant and animal species with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
