Pacific Parakeet
The Pacific parakeet or Nicaraguan green conure (''Psittacara strenuus'') is a species of parakeet. Some ornithologists consider it a subspecies of the green parakeet (''Psittacara holochlorus''), however it is considered a full species according to the IOC World Bird List. This bird is endemic to a small area in western Nicaragua, the Chocoyero-El Brujo Natural Reserve. Nesting sites lie within this protected area, but the birds still face threats from the outside world when they leave the reserve to feed. Nonetheless, its population is considered not immediately threatened (especially compared to some of its relatives such as the Socorro parakeet), and when BirdLife and the 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 natu ... considered it a good species, it was listed as ' ...

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' (1912).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parakeet
A parakeet is any one of many small to medium-sized species of parrot, in multiple Genus, genera, that generally has long tail feathers. Etymology and naming The name ''parakeet'' is derived from the French wor''perroquet'' which is reflected in some older spellings that are still sometimes encountered, including paroquet or paraquet. However, in modern French''perruche''is used to refer to parakeets and similar-sized parrots. In American English, the word ''parakeet'' usually refers to the budgerigar, which is one species of parakeet. Summary Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. The Australian budgerigar, also known as "budgie", ''Melopsittacus undulatus'', is probably the most common parakeet. It was first described by zoologists in 1891. It is the most popular species of parakeet kept as a pet in North America and Europe. The term "grass parakeet" (or ''grasskeet'') refer ...

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] |
Green Parakeet
The green parakeet (''Psittacara holochlorus'') is a medium-sized parrot occurring in North and Central America, from the southernmost tip of Texas south to northern Nicaragua. Description The green parakeet is 32 cm in length, and is mostly green in color. It also has a yellow beak. Diet It feeds on seeds, various fruits, and corn. It can sometimes be considered a crop pest. Habitat Wild birds primarily use scrub and swamp forests, woodlands, and forest clearings. The US population takes advantage of palm groves in cities. Taxonomy This species was formerly placed in the genus'' Aratinga'' as ''A. holochlora'', and divided into various subspecies (''A. h. holochlora, A. h. brevipes, A. h. brewsteri, A. h. strenua,'' and ''A. h. rubritorquis''). Later, it was split into three species as the green conure (''A. holochlora''), Pacific conure (''A. strenua''), and Socorro conure (''A. brevipes''). Today it is recognised as single species with a highly threatened subspecie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IOC World Bird List
''Birds of the World: Recommended English Names'' is a paperback book, written by Frank Gill and Minturn Wright on behalf of the International Ornithologists' Union. The book is an attempt to produce a standardized set of English names for all bird species, and it is the product of a project set in motion at the 1990 International Ornithological Congress. It is supplemented by a website, the IOC World Bird List, giving updates to the published material. An 11-page introduction deals with a number of issues which relate to the naming of birds. This is followed by a systematic list, from pages 12 to 211, and a 46-page index. The family sequence is that of the third edition of the '' Howard and Moore Complete Checklist of the Birds of the World''. The book's cover is illustrated with a photo of a helmet vanga, a bird endemic to Madagascar.Gill, Frank, and Minturn Wright, ''Birds of the World: Recommended English Names''; Princeton University Press, 2006.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicaragua
Nicaragua (; ), officially the Republic of Nicaragua (), is the largest country in Central America, bordered by Honduras to the north, the Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to the west. Managua is the country's capital and largest city. , it was estimated to be the second largest city in Central America. Nicaragua's multiethnic population of six million includes people of mestizo, indigenous, European and African heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak their own languages and English. Originally inhabited by various indigenous cultures since ancient times, the region was conquered by the Spanish Empire in the 16th century. Nicaragua gained independence from Spain in 1821. The Mosquito Coast followed a different historical path, being colonized by the English in the 17th century and later coming under British rule. It became an autonomous territory of Nicaragua in 1860 and its northernmost part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chocoyero-El Brujo Natural Reserve
Chocoyero-El Brujo Natural Reserve (Spanish: ''Reserva Natural El Chocoyero-El Brujo'') is located in the municipality of Ticuantepe in the Managua department of Nicaragua. Chocoyero-El Brujo is one of 78 protected areas in Nicaragua, and at just this tropical forest is one of the smallest in size. Chocoyero-El Brujo was declared a natural reserve in 1993 is managed by the Ministry of the Environment and Natural Resources (MARENA). Flora and fauna Chocoyero-El Brujo is abundant in water, it is home to two waterfalls, El Brujo and Chocoyero, named after the parakeets that make the walls of the cliff their home. The abundance of water keeps this natural reserve green with flourishing wildlife. Chocoyero-El Brujo is a main supplier of water to Managua, it supplies 20% of the city's water consumption and about twenty million gallons of water each and every day. The large amount of biodiversity is obvious, with bird species estimated at 113 species, some of which include toucans, humm ...

Socorro Parakeet
The Socorro parakeet (''Psittacara brevipes'') is a species of parrot endemic to Socorro Island in the Revillagigedo Islands, Mexico. Some ornithologists consider it to be a subspecies of the green parakeet (''Psittacara holochlorus''). Its natural habitat is tropical and subtropical moist broadleaf forests. The Socorro parakeet's mating season starts in November. Status It is threatened by habitat destruction due to feral sheep and predation by feral cats. At present, there is no clear evidence of population decline. However, due to the restricted distribution and small population size of this species, it may meet the IUCN criteria for a vulnerable species A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, ....Martínez-Gómez, J.
