James Lee Peters
James Lee Peters (August 13, 1889 – April 19, 1952) was an American ornithologist. He was born in Boston, Massachusetts to Dr. Austin Peters and Francis Howie Lee on August 13, 1889. His early education was at the Roxbury Latin School, followed by his acceptance to Harvard University, where he graduated in 1912. Peters interest in natural history developed early. His early collecting trips included traveling with Arthur Cleveland Bent, Charles Haskins Townsend and H.K. Job to the Magdalen Islands. Three of Peters early mentors were Charles Johnson Maynard, judge Charles Jenney and Outram Bangs.Wetmore, A. " In Memoriam: James Lee Peters" The Auk. Vol. 74. No. 2, April 1957 Ultimately, Peters was Curator of Birds at the Museum of Comparative Zoology, at Harvard University. He served as president of the American Ornithologists' Union in 1942–45, and also served as president of International Commission on Zoological Nomenclature for a period. Peters is best known for his mul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoseisura
The cacholotes are four species of relatively large, heavy-billed furnariids in the genus ''Pseudoseisura''. They are found in shrubby habitats in the South American countries of Brazil, Bolivia, Argentina, Paraguay and Uruguay. They are essentially brown (ranging from deep rufous to pale gray-brown depending on species), and all are crested to some extent. Taxonomy The genus ''Pseudoseisura'' was introduced in 1853 by the German naturalist Ludwig Reichenbach to accommodate the white-throated cacholote. The name combines the Ancient Greek ''pseudos'' meaning "false" and ''seisoura'', a bird mentioned by the Greek lexicologist Hesychius of Alexandria and believed to be a wagtail ''Motacilla''. Species The genus contains four extant species: The allopatric Caatinga and gray-crested cacholotes were formerly considered conspecific under the name rufous cacholote (''Pseudoseisura cristata''). Fossil species: *†''Pseudoseisura cursor'' (Pleistocene of Argentina) References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Uruguay
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 furth ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

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 321 species and 71 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 si ...

Río Negro Province
Río Negro (, ''Black River'') is a province of Argentina, located in northern Patagonia. Neighboring provinces are from the south clockwise Chubut, Neuquén, Mendoza, La Pampa and Buenos Aires. To the east lies the Atlantic Ocean. Its capital is Viedma near the Atlantic outlet of the province's namesake river in the eastern extreme. The largest city is in the Andean foothills Bariloche in the far west. Other important cities include General Roca and Cipolletti. History Ferdinand Magellan was the first European explorer to visit the coasts of the provinces in 1520. Italian priest Nicolás Mascardi founded the Jesuit mission ''Nuestra Señora de Nahuel Huapi'' in 1670 at the shore of the Nahuel Huapi Lake, at the feet of the Andes range. Originally part of the Argentine territory called Patagonia (in 1878 the ''Gobernación de la Patagonia''), in 1884 it was organised into the ''Territorio Nacional del Río Negro'' and General Lorenzo Vintter was appointed as the ...

Mandible
In jawed vertebrates, the mandible (from the Latin ''mandibula'', 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing Temporomandibular joint, joints with the cranium's temporal bones. The mandible hosts the lower Human tooth, teeth (their depth delineated by the alveolar process). Many muscles attach to the bone, which also hosts nerves (some connecting to the teeth) and blood vessels. Amongst other functions, the jawbone is essential for chewing food. Owing to the Neolithic Revolution, Neolithic advent of agriculture (), human jaws evolved to be Human jaw shrinkage, smaller. Although it is the strongest bone of the facial skeleton, the mandible tends to deform in old age; it is also subject to Mandibular fracture, fracturing. Surgery allows for the removal of jawbone fragments (or its entirety) as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxilla
In vertebrates, the maxilla (: maxillae ) 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. Anatomy Structure The maxilla is a paired bone - the two maxillae unite with each other at the intermaxillary suture. The maxilla consists of: * The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. * Four processes: ** the zygomatic process ** the frontal process ** the alveolar process ** the palatine process It has three surfaces: * the anterior, posterior, medial Features of the maxilla include: * t ...

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 The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
