Amazona Gomezgarzai
The blue-winged amazon (''Amazona gomezgarzai'') is a proposed Central American species of parrot living in the Yucatan Peninsula, Mexico. It was described in 2017 in the journal ''PeerJ''; however, its existence as a distinct wild species native to the Yucatan Peninsula has been questioned. A critique published in the journal Zootaxa identified numerous weaknesses with the description and suggested that the most plausible hypothesis was that the two specimens on which the description was based were hybrids. Description The proposed species was described as having an average body length of and a body weight of . It is characterized by distinct sexual dimorphism, with males larger than females. Depending on the sex, wing length is and the tail length is . Most of the body is covered with green plumage. However, these parrots differ in size and detail of the colors of the plumage from other Amazons found on the Yucatan peninsula (i.e., the white-fronted amazon – ''Amazona alb ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Forehead
In human anatomy, the forehead is an area of the head bounded by three features, two of the skull and one of the scalp. The top of the forehead is marked by the hairline, the edge of the area where hair on the scalp grows. The bottom of the forehead is marked by the supraorbital ridge, the bone feature of the skull above the eyes. The two sides of the forehead are marked by the temporal ridge, a bone feature that links the supraorbital ridge to the coronal suture line and beyond. However, the eyebrows do not form part of the forehead. In '' Terminologia Anatomica'', ''sinciput'' is given as the Latin equivalent to "forehead" (etymology of ''sinciput'': from ''semi-'' "half" and ''caput'' "head".). Structure The bone of the forehead is the squamous part of the frontal bone. The overlying muscles are the occipitofrontalis, procerus, and corrugator supercilii muscles, all of which are controlled by the temporal branch of the facial nerve. The sensory nerves of the forehea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

International Union For Conservation Of Nature
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 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 building partners ...

Tony Silva
Tony Silva, also known as Antonio H. Silva (born 1960) is an American aviculturist and ornithologist, and the author of books and articles about parrots. From 1989 to 1992, he was curator of birds at Loro Parque, the largest parrot park in the world. In 1996, he was convicted of conspiring to smuggle rare parrots into the United States and of tax evasion. Early life and career Silva was born in Cuba in 1960 and immigrated to the United States with his parents at a young age. His parents encouraged his love of birds as a hobby to keep him out of trouble, and he began studying, collecting, and breeding birds at age nine. Silva became enamoured with parrots at age 10 when he discovered macaws at a local pet store. When he was in his teens, he became further enamoured after receiving a parakeet. Silva's aviary was originally financed by his father (who owned a company that manufactured television components), later supplemented by his own income from breeding parrots, judging parr ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It als ...

Hawk
Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents, except Antarctica. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks, and others. This subfamily are mainly woodland birds with short broad wings, long tails, and high visual acuity. They hunt by dashing suddenly from a concealed perch. In America, members of the '' Buteo'' group are also called hawks, though birds of this group are called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged and shorter-tailed than accipiters, and fly further distances in open areas. Buteos descend or pounce on their prey rather than engaging in fast, horizontal pursuit. The terms ''accipitrine hawk'' and ''buteonine hawk'' are used to distinguish between the types in regions where ''hawk'' applies to both. The term ''"true hawk"'' is sometimes used for the accipitrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices ( or ), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds still r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
