Neotropical Parrots
The neotropical parrots or New World parrots comprise about 150 species in 32 genera found throughout South and Central America, Mexico, the Caribbean islands and (formerly) the southern United States. Among them are some of the most familiar and iconic parrots, including the blue and gold macaw, sun conure, and yellow-headed amazon. The parrots of the New World have been known to Europeans since Columbus remarked upon them in his journal in 1492. Systematic descriptions of the birds were first available in German naturalist Georg Marcgraf's ''Historia Naturalis Brasiliae'' published in 1648, and English naturalist Mark Catesby's two-volume ''Natural History of Carolina, Florida and the Bahama Islands'' published in London in 1731 and 1743. Several species and one genus have become extinct in recent centuries. A second genus is extinct in the wild. Over a third of the extant species are classified as threatened by the IUCN. A few of these are in imminent danger of extinction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-and-yellow Macaw
The blue-and-yellow macaw (''Ara ararauna''), also known as the blue-and-gold macaw, is a large South American parrot with mostly blue top parts and light orange underparts, with gradient hues of green on top of its head. It is a member of the large group of neotropical parrots known as macaws. It inhabits forest (especially varzea, but also in open sections of ''terra firme'' or unflooded forest), woodland and savannah of tropical South America. They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. They can also live for 65–70 years. Taxonomy The blue-and-yellow macaw was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with all the other parrots in the genus ''Psittacus'' and coined the binomial name ''Psittacus ararauna''. This macaw is now one of the eight extant species placed in the genus '' Ara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark Catesby
Mark Catesby (24 March 1683 – 23 December 1749) was an English naturalist who studied the flora and fauna of the New World. Between 1729 and 1747 Catesby published his ''Natural History of Carolina, Florida and the Bahama Islands'', the first published account of the flora and fauna of North America. It included 220 plates of birds, reptiles, amphibians, fish, insects, mammals and plants. Life and works Catesby was born on 24 March 1683 and baptised at Castle Hedingham, Essex on 30 March 1683. His father, John Catesby (buried 12 November 1703), was a local politician and gentleman farmer. His mother was Elizabeth Jekyll (buried 5 September 1708). The family owned a farm and house, Holgate, in Sudbury, Suffolk as well as property in London. An acquaintance with the naturalist John Ray led to Catesby becoming interested in natural history. The death of his father left Catesby enough to live on, so in 1712, he accompanied his sister Elizabeth to Williamsburg, Virginia. She ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigo-winged Parrot
Fuertes's parrot (''Hapalopsittaca fuertesi''), also known as the indigo-winged parrot, is a parrot which has a highly restricted range on the west slope of the Central Andes of Colombia. It is classified by the IUCN as being critically endangered. It is threatened by deforestation. Description Fuertes's parrot is about 24 cm longdel hoyo, J. Elliott, A. and Sargatal, J. (1997) Handbook of the Birds of the World Volume 4: Sandgrouse to Cuckoos Lynx Edicions, Barcelona and is green with indigo wing feathers, red shoulders, and a blue crown. The bird's pale ivory bill has chestnut feathers at the base. It was rediscovered in 2002 after an absence of 91 years on the slopes of a volcano in Colombia.

Puerto Rican Parrot
The Puerto Rican amazon (''Amazona vittata''), also known as the Puerto Rican parrot (Puerto Rican Spanish: ''cotorra puertorriqueña'') or ''iguaca'', is the only extant parrot endemic to the archipelago of Puerto Rico, and belongs to the Neotropical genus ''Amazona''. Measuring , the bird is a predominantly green parrot with a red forehead and white rings around the eyes. Its closest relatives are believed to be the Cuban amazon (''Amazona leucocephala'') and the Hispaniolan amazon (''Amazona ventralis''). The Puerto Rican amazon reaches sexual maturity at between three and four years of age. It reproduces once a year and is a cavity nester. Once the female lays eggs she will remain in the nest and continuously incubate them until hatching. The chicks are fed by both parents and will fledge 60 to 65 days after hatching. This parrot's diet is varied and consists of flowers, fruits, leaves, bark and nectar obtained from the forest canopy. The species is the only remaining na ...

Blue-throated Macaw
The blue-throated macaw (''Ara glaucogularis''), also known as the Caninde macaw or Wagler's macaw, is a macaw endemic to a small area of north-central Bolivia, known as Los Llanos de Moxos. In 2014 this species was designated by law as a natural patrimony of Bolivia, where it is known as ''barba azul'', which means 'blue beard' in Spanish. Until 2010, it was hunted by natives to make feathered "Moxeño" headdresses for "machetero" ritual dances. Recent population and range estimates suggest that about 350–400 individuals remain in the wild. Its demise was brought upon by nesting competition, avian predation, and a small native range, exacerbated by indigenous hunting and capture for the pet trade. Although plentiful in captivity, it is Critically Endangered in the wild and is protected by trading prohibitions. The name "Wagler's macaw" is in honor of German herpetologist Johann Georg Wagler, who processed many of Johan Baptist von Spix's Brazilian collections at the Ludw ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. 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 partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not conside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, ''recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species (" Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: * Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) * Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) * Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) * Franklinia (last seen in 1803, listed extinct in the wild since 1998) * Golden skiffia (listed extinct in the wild since 1996) * Guam kingfisher (listed extinct in the wild since 1986) * Hawaiian crow or ʻalalā (last seen in 20 ...
