Riparian Parrotlet
The riparian parrotlet (''Forpus crassirostris'') or large-billed parrotlet is a species of parrot in the family Psittacidae. Description Riparian parrotlets are typically long and weigh about . Their bodies are mostly yellow-green. Eyes are dark brown and beaks and feet are light peach. Riparian parrotlets are sexually dimorphic: males have blue rumps and lower backs, with blue feathers along the leading edges of their wings and blue secondaries; primary coverts are blue-gray. Females have no blue feathers and a yellow-green belly. Distribution and habitat Riparian parrotlets are found in southeastern Colombia to northern Peru and western Brazil. There is a small population on São Sebastião Island. Though they do not fully migrate, it has been suggested that riparian parrotlets are altitudinal migrants: abundance of the species in lowland areas increased during winter and spring; this is likely because during these seasons, the main plants of the large-billed parro ...

Władysław Taczanowski
Władysław Taczanowski (; 17 March 1819, in Jabłonna, Lublin Voivodeship – 17 January 1890, in Warsaw) was a Polish zoologist and collector of natural history who explored the Russian Far East and northern Africa. He specialized mainly in ornithology but also described numerous other taxa including reptiles and arachnids. Life A member of an old noble ('' szlachta'') magnate family, Taczanowski, from the Poznań region Władysław studied in Lublin and managed the family farm after the death of his father. He then joined government service and served on special missions of the governor of Radom. He joined the Warsaw University Museum in 1855 and began to travel and train at other museums. In 1865 he joined Benedict Dybowski and Victor Godlewski on expeditions to Eastern Russia. In 1862 he succeeded Feliks Paweł Jarocki as curator. Taczanowski took part in an expedition to Algeria with Antoni S. Waga (1866–67) and wrote several significant studies including ''Birds of Pol ...

Forpus
''Forpus'' is a genus of neotropical parrots in the family Psittacidae. It is the only genus in the Forpini tribe of the subfamily Arinae. Taxonomy The genus ''Forpus'' was introduced in 1858 by the German zoologist Friedrich Boie. The type species was subsequently designated as the green-rumped parrotlet. The etymology of the genus name is unknown. The genus contains nine species: * Mexican parrotlet (''Forpus cyanopygius'') **Grayson's parrotlet or Tres Marias parrotlet (''Forpus cyanopygius insularis'') * Green-rumped parrotlet (''Forpus passerinus'') **Colombian green-rumped parrotlet or Rio Hacha parrotlet (''Forpus passerinus cyanophanes)'' **Trinidad green-rumped parrotlet or Venezuelan parrotlet (''Forpus passerinus viridissimus'') **Roraima green-rumped parrotlet or Schlegel's parrotlet (''Forpus passerinus cyanochlorus'') **Amazon green-rumped parrotlet or delicate parrotlet or Santarem passerine parrotlet (''Forpus passerinus deliciosus'') * Cobalt-rumped par ...

Birds Described In 1883
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. Birds ...

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.

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, ''The Auk'' and '' The Condor'' as well as the ''AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.

Cobalt-rumped Parrotlet
The cobalt-rumped parrotlet (''Forpus xanthopterygius'') or blue-winged parrotlet is a species of parrot in the family Psittacidae. There are two subspecies: Salvadori's cobalt-rumped parrotlet (''F. x. flavescens'') and Hellmayr's cobalt-rumped parrotlet (''F. x. flavissimus''). Description Distribution and habitat Cobalt-rumped parrotlets are found in much of central and northern South America. Their range is split by each subspecies, as described above. It is generally common and widespread, though more localized in the Amazon Basin. Cobalt-rumped parrotlets are mainly found in lowlands. They occur in dry and riparian woodlands, cerrado, caatinga, palm groves, semi-arid scrubland, savanna, and pastures. Cobalt-rumped parrotlets tend to avoid densely forested areas. They are not found at altitudes above . Cobalt-rumped parrotlets are generally non-migratory; however, populations in Argentina move locally according to the flowering seasons of various plant spec ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handroanthus Serratifolius
''Handroanthus serratifolius'' is a species of tree, commonly known as yellow lapacho, pau d'arco, yellow poui, yellow ipe, pau d'arco amarelo, or ''ipê-amarelo''. Description It is a tree native to forests throughout Central and South America. This plant grows in the cerrado vegetation of Brazil, reaching up to French Guiana, Bolivia, Paraguay and Northern Argentina. It is one of the largest and strongest of tropical forest trees, growing up to tall while the base can be in diameter. Uses It is a commercially farmed hardwood notable for its extreme hardness and resistance to fire and pests. It is sometimes traded as an " ironwood", or just as " ipê" (the entire genus ''Tabebuia''), or as lapacho (properly ''Handroanthus serratifolius'') Chemistry The bark of ''Handroanthus serratifolius'' contains chemical compounds including lapachol, quercetin, and other flavonoid Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their co ...

Cecropia
''Cecropia'' is a Neotropical genus consisting of 61 recognized species with a highly distinctive lineage of dioecious trees. The genus consists of pioneer trees in the more or less humid parts of the Neotropics, with the majority of the species being myrmecophytic.Berg, Rosselli & Davidson (2005) Berg and Rosselli state that the genus is characterized by some unusual traits: spathes fully enclosing the flower-bearing parts of the inflorescences until anthesis, patches of dense indumentums (trichilia) producing Mullerian (food) at the base of the petiole, and anthers becoming detached at anthesis. ''Cecropia'' is most studied for its ecological role and association with ants. Its classification is controversial; in the past, it has been placed in the Cecropiaceae, Moraceae (the mulberry family), or Urticaceae (the nettle family).Burger (1977) The modern Angiosperm Phylogeny Group system places the "cecropiacean" group in the Urticaceae. The genus is native to the American tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Tree
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance ...

Incubate (biology)
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring. In birds in contrast, the sex of offspring is genetically determined, but in many species a constant and particular temperature is necessary for successful incubation. Especially in poultry, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production. Avian incubation A wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
