Diving Duck
The diving ducks, commonly called pochards or scaups, are a category of duck which feed by diving beneath the surface of the water. They are part of Anatidae, the diverse and very large family that includes ducks, geese, and swans. The diving ducks are placed in a distinct tribe in the subfamily Anatinae, the Aythyini. While morphologically close to the dabbling ducks, there are nonetheless some pronounced differences such as in the structure of the trachea. mtDNA cytochrome ''b'' and NADH dehydrogenase subunit 2 sequence data indicate that the dabbling and diving ducks are fairly distant from each other, the outward similarities being due to convergent evolution. Alternatively, the diving ducks are placed as a subfamily Aythyinae in the family Anatidae which would encompass all duck-like birds except the whistling-ducks. The seaducks commonly found in coastal areas, such as the long-tailed duck (formerly known in the U.S. as oldsquaw), scoters, goldeneyes, mergansers, bu ...

Rosy-billed Pochard
The rosy-billed pochard (''Netta peposaca''), alternatively named rosybill or rosybill pochard, is a member of family Anatidae. Though classified as a diving duck, this pochard feeds more like a dabbling duck feeding on seeds roots, sedges, aquatic plants and other grasses. ''Netta'' is Ancient Greek for "duck" and ''peposaca'' is a transcription of the Guaraní name of this species which means "showy wings", referring to the broad white stripe that is only visible with stretched out wings. Male characteristic features include a bright red bill with a rounded knob at the base. The rosy-billed pochard is endemic to South America. It is found in Argentina, central Chile, Paraguay, Uruguay and southern Brazil. The population in southern Argentina migrates northward during the austral winter, reaching Brazil and southern Bolivia. It is a vagrant to the Falkland Islands. Taxonomy The rosy-billed pochard is one of five pochard species that make up the genus ''Netta,'' which is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scirpus Californicus
''Schoeneoplectus californicus'' is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush. It is also sometimes called "tule", but the closely related '' Schoenoplectus acutus'' is the species most often referred to by that name.

American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, Ornithology' (formerly ''The Auk)'' and Ornithological Applications' (formerly '' The Condor)'' as well as the '' AOS Checklist of North American Birds''. The American Ornithological Society claims the authority to establish standardized English bird names throughout North and South Americas. In 2013, the American Ornithologists' Union (AOU) announced a collaboration with the Cooper Ornithological Society, streamlining operations through joint meetings, a shared publishing office, and a reorientation of their journals. By October 2016, the AOU ceased its independent status, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkland Islands
The Falkland Islands (; ), commonly referred to as The Falklands, is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British Overseas Territory, the Falklands have internal self-governance, while the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley, Falkland Islands, Stanley on East Falkland. The islands are believed to have been uninhabited prior to European discovery in the 17th century. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements.

Vermiculation
Vermiculation is a surface pattern of dense but irregular lines, so called from the Latin meaning "little worm" because the shapes resemble worms, worm casts, or worm tracks in mud or wet sand. The word may be used in a number of contexts for patterns that have little in common. The adjective vermiculated is more often used than the noun. Vermiculation naturally occurs in patterns on a wide variety of species, for example in the feathers of certain birds, for which it may provide either camouflageSee, e.g., Iain Campbell, Sam Woods, Nick Leseberg, ''Birds of Australia: A Photographic Guide'' (2014), p. 110. or decoration. Several species are named after this trait, either in English or by the Latin ''vermicularis''. It also appears in architecture as a form of Rustication (architecture), rustication where the stone is cut with a pattern of wandering lines. In metalwork, vermiculation is used to form a type of background found in Romanesque art, Romanesque enamels, especially o ...

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 ...
