Golden-capped Conure
The golden-capped parakeet (''Aratinga auricapillus'') is a species of parrot in the family Psittacidae found in Brazil and Paraguay. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, dry savanna, and plantations. It is threatened by habitat loss. The ''A. auricapillus'' is a good biological indicator because of its vulnerability, high detectability as well as its sensitivity to forest fragmentation. Description It is long and mostly green with a black beak, white eyerings, orange-red belly, and red face fading to yellow over the crown. Juvenile members of the ''A. auricapillus'' group develop their yellow head markings and red coloration on the lower body in adulthood. The approximate weight for golden-capped parakeets is 4.9-5.25 oz.“Golden-capped Conure” ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Heinrich Kuhl
Heinrich Kuhl (17 September 1797 – 14 September 1821) was a German people, German naturalist and zoologist. Kuhl was born in Hanau (Hesse, Germany). Between 1817 and 1820, he was the assistant of professor Th. van Swinderen, docent natural history at the University of Groningen in Groningen (the Netherlands). In 1817, he published a monograph on bats, and in 1819, he published a survey of the parrots, ''Conspectus psittacorum''. He also published the first monograph on the petrels, and a list of all the birds illustrated in Edme-Louis Daubenton, Daubenton's ''Planches Enluminées'' and with his friend Johan Coenraad van Hasselt (1797–1823) ''Beiträge zur Zoologie und vergleichenden Anatomie'' ("Contributions to Zoology and Comparative Anatomy") that were published at Frankfurt-am-Main, 1820. In 1820, he became assistant to Coenraad Jacob Temminck at the Leiden Rijksmuseum van Natuurlijke Historie. He then travelled to Java (island), Java, then part of the colonial Netherla ...

Polytypic Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ...

Birds Of Brazil
Brazil has one of the richest bird diversities in the world. The avifauna of Brazil include a total of 1858 confirmed species of which 238 are endemic. Five have been introduced by humans, 96 are rare or vagrants, and five are extinct or extirpated. An additional 14 species are hypothetical (see below). Brazil hosts about 60% of the bird species recorded for all of South America. These numbers are still increasing almost every year, due to new occurrences, new species being described, or splits of existing species. About 10% of the bird species found in Brazil are, nonetheless, threatened. In June 2013 a simultaneous discovery of fifteen bird species in Brazil was announced, the first such since 1871, when August von Pelzeln described forty new species. The birds were from the families Corvidae, Thamnophilidae, Dendrocolaptidae, Tyrannidae, and Polioptilidae. Eleven of the new species are endemics of Brazil and four also inhabit Peru and Bolivia.

Birds Of The Atlantic Forest
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. Bird ...

Aratinga
''Aratinga'' is a genus of South American conures. Most are predominantly green, although a few are predominantly yellow or orange. They are social and commonly seen in groups in the wild. In Brazil, the popular name of several species usually is ''jandaia'', sometimes written as ''jandaya'' in the scientific form. Many species from this genus are popular pets, although being larger than the members of the genus ''Pyrrhura'', they need a sizable aviary to thrive. Taxonomy The genus ''Aratinga'' was introduced in 1824 by the German naturalist Johann Baptist von Spix. The type species was subsequently designated as the sun parakeet. The genus name is from the extinct Tupi language of Brasil. ''Ará tinga'' means "bright bird" or "bright parrot". The taxonomy of this genus has recently been resolved by splitting it in four genera, as the genus as previously defined was paraphyletic. The species of the '' Aratinga solstitialis'' complex, were retained in this genus, while other form ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Melia Azedarach
''Melia azedarach'', commonly known as the chinaberry tree, pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, Indian lilac, or white cedar, is a species of deciduous tree in the mahogany family, Meliaceae, that is native to Indomalaya and Australasia. Description The fully grown tree has a rounded crown, and commonly measures tall, exceptionally . The leaves are up to long, alternate, long-petioled, two or three times compound (odd-pinnate); the leaflets are dark green above and lighter green below, with serrate margins. The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The fruit is a drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming wrinkled and almost white. As the stem ages and grows, changes occur that transform its surface into bark. Chemistry Italo et al 2009 and Safithri and Sari 2016 report flavonoids and phenols found in ''M. azed ...

Pterogyne
''Pterogyne'' is a monotypic genus in the legume family, Fabaceae. The sole species is ''Pterogyne nitens''. Spanish common names include guiraró, palo coca, or tipa colorado. In Portuguese, it is commonly known as amendoim bravo, cocal or madeira nova. It is found in Brazil, Paraguay, Bolivia and Argentina. It is threatened by habitat loss and harvesting for timber. Five guanidine alkaloid natural products were isolated from the leaves of ''Pterogyne nitens: nitensidine D, nitensidine E, pterogynine, pterogynidine, and galegine Galegine is a toxic chemical compound that has been isolated from Goat's rue (''Galega officinalis'').

Psidium Guajava
''Psidium guajava'', the common guava, yellow guava, lemon guava, or apple guava is an evergreen shrub or small tree native to the Caribbean, Central America and South America. It is easily pollinated by insects; when cultivated, it is pollinated mainly by the common honey bee, ''Apis mellifera''. Overview Widely cultivated in tropical and subtropical regions around the world, guava fruits can range in size from as small as an apricot to as large as a grapefruit. Various cultivars have white, pink, or red flesh; a few varieties feature red (instead of green or yellow) skin. When cultivated from seed, guavas are notable for their extremely slow growth rate for several months, before a very rapid acceleration in growth rate takes over. From seed, common guavas may bloom and set fruit in as few as two years or as many as eight. Cuttings, grafting, and air layering are more commonly used as a propagation method in commercial groves. Highly adaptable, guavas can be easily grown a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ceiba Speciosa
''Ceiba speciosa'', the floss silk tree (formerly ''Chorisia speciosa''), is a species of deciduous tree that is native to the tropical and subtropical forests of South America. It has several local common names, such as ''palo borracho'' (in Spanish literally "drunken stick"), or '' árbol del puente'', ''samu'ũ'' (in Guarani), or ''paineira'' (in Brazilian Portuguese). In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree". In the USA it often is called the silk floss tree. It belongs to the same family as the baobab; the species ''Bombax ceiba''; and other kapok trees. Another tree of the same genus, '' Ceiba chodatii'', is often referred to by the same common names. Description The natural habitat of the floss silk tree is in the northeast of Argentina, east of Bolivia, Paraguay, Uruguay, and southern Brazil. It is resistant to drought and moderate cold. It grows fast in spurts when water is abundant, and sometimes reaches more than in height. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Fledgling (birds)
Fledging is the stage in a flying animal's life between hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Network defines the phenophase (or life cycle stage) of fledged young for birds as "One or more young are seen recently departed from the nest. This includes young incapable of sustained fli ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
