Aratinga Holochlora
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] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Thick-billed Parrot
The thick-billed parrot (''Rhynchopsitta pachyrhyncha'') is a medium-sized parrot endemic to Mexico that formerly ranged into the southwestern United States. Its position in parrot phylogeny is the subject of ongoing discussion; it is sometimes referred to as thick-billed macaw or thick-billed conure. In Mexico, it is locally called ''guacamaya'' ("macaw") or ''cotorra serrana'' ("mountain parrot"). Classified internationally as Endangered through IUCN, the thick-billed parrot's decline has been central to multiple controversies over wildlife management. In 2018, the estimated wild population in Mexico was 1,700. Taxonomy ''Pachyrhyncha'' is currently classified as a species of the genus ''Rhynchopsitta'' of macaw-like thick-billed parrots of which there are two extant species (the other being the maroon-fronted parrot), and one extinct species. However, recent molecular DNA studies indicate that ''pachyrhyncha'' and its sister species ''terrisi'' in genus ''Rhynchopsitta'' are ...

Birds Of Mexico
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psittacara
''Psittacara'' is a genus of parakeets in the tribe Arini. Species of the genus are found in Central and South America, the Caribbean and one species reaching the southern United States. Until 2013, all the species were placed in the genus ''Aratinga''. Many of the ''Psittacara'' species are kept in aviculture or as companion parrots, where they are commonly known as conures. Taxonomy The members of this genus were formerly placed in the genus ''Aratinga''. Molecular phylogenetic studies had found that ''Aratinga'' was non-monophyletic so in order to create monophylectic genera James Van Remsen Jr. and collaborators proposed in 2013 that ''Aratinga'' should be split and a group of species moved to the resurrected genus ''Psittacara''. The genus had been introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors with the white-eyed parakeet as the type species. Species The genus contains 13 species including one which is now extinct: * Green parakeet (''Psittacara holoch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral
A feral () animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded a ...

Rio Grande Valley (Texas)
The Lower Rio Grande Valley ( es, Valle del Río Grande), commonly known as the Rio Grande Valley or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. It consists of the Brownsville, Harlingen, Weslaco, Pharr, McAllen, Edinburg, Mission, San Juan, and Rio Grande City metropolitan areas in the United States and the Matamoros, Río Bravo, and Reynosa metropolitan areas in Mexico. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called ''colonias''. A large seasonal influx occurs of "winter Texans" — people who come down from the north for the winter and then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-crowned Amazon
The red-crowned amazon (''Amazona viridigenalis''), also known as the red-crowned parrot, green-cheeked amazon or Mexican red-headed parrot, is an endangered amazon parrot native to northeastern Mexico and possibly southern Texas in the United States. A 1994 study estimated wild populations of between 2,000 and 4,300 mature individuals; the IUCN Red List considers it a globally endangered species with a decreasing population. The main threats to the native bird's survival are the illegal export of trapped birds from Mexico to the United States for the pet trade and the destruction of their natural habitat, the lowland forests of northeastern Mexico. Description Their appearance is generally green with the most notable features being a bright red forehead and crown, dark blue streak behind the eyes, and light green cheeks. It is not uncommon for red-crowned amazons to have splashes of red and blue under their wings and have light yellow-tipped tails. They have a white eye-ring wh ...

Extirpation
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The numbe ...

Carolina Parakeet
The Carolina parakeet (''Conuropsis carolinensis''), or Carolina conure, is an extinct species of small green neotropical parrot with a bright yellow head, reddish orange face and pale beak that was native to the eastern, Midwest and plains states of the United States. It was the only indigenous parrot within its range, as well as one of only three parrot species native to the United States (the others being the thick-billed parrot, now extirpated, and the green parakeet, still present in Texas; a fourth parrot species, the red-crowned amazon, is debated). The Carolina parakeet was found from southern New York and Wisconsin to Kentucky, Tennessee and the Gulf of Mexico, from the Atlantic seaboard to as far west as eastern Colorado. It lived in old-growth forests along rivers and in swamps. It was called ''puzzi la née'' ("head of yellow") or ''pot pot chee'' by the Seminole and ''kelinky'' in Chickasaw. Though formerly prevalent within its range, the bird had become rare by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
