Solitary Cacique
The solitary cacique or solitary black cacique (''Cacicus solitarius'') is a species of bird in the family Icteridae. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, Uruguay, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and heavily degraded former forest. It is a fairly common bird with a very extensive range so the IUCN has rated it as a "species of least concern". Description The male solitary cacique has a length of about and the female . It differs from all other entirely black birds with dark irises within its range, by having a large white, chisel-shaped, sharply-pointed beak. It could be confused with the Ecuadorian cacique (''Cacicus sclateri''), but that is smaller and has a restricted range, or the yellow-billed cacique (''Amblycercus holosericeus''), but that is not found east of the Andes. It has a range of different vocalizations which are mostly delivered at a me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

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 Amazon Basin
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 ...

Cacicus
The caciques are passerine birds in the New World blackbird family which are resident breeders in tropical South America north to Mexico. All of the group are in currently placed in the genus ''Cacicus'', except the aberrant yellow-billed cacique (''Amblycercus holosericeus''), and the Mexican cacique (''Cassiculus melanicterus'') which constitute respective monotypic genera. Judging from mitochondrial DNA cytochrome ''b'' and NADH dehydrogenase subunit 2 sequence (Price & Lanyon 2002), the aberrant oropendolas band-tailed oropendola (''Ocyalus latirostris'') and casqued oropendola, ''Psarocolius oseryi'' (''Ocyalus oseryi''?) seem to be closer to the caciques. The caciques are birds associated with woodland or forest. Most are colonial breeders, with several long, hanging, bag-shaped nests in a tree, each suspended from the end of a branch. Some species choose a tree that also contains an active wasp nest (such as ''Polybia rejecta'') as a deterrent to predators (e.g. toucans ...

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-billed Cacique
The yellow-billed cacique (''Amblycercus holosericeus'') is a species of cacique in the family Icteridae. It is monotypic within the genus ''Amblycercus''. There is some question as to whether or not it is a true cacique. The plumage is entirely black. The legs and feet are dark gray. The eye is yellow or yellow-orange. The bill is yellow with a gray tinge. Measures long. It is found in Belize, Bolivia, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, and Venezuela. Three subspecies are known: * ''A. h. holosericeus'' – ( Deppe, 1830): nominate, found from southeastern Mexico to northwestern Colombia * ''A. h. flavirostris'' – Chapman, 1915: found from western Colombia to northern Peru * ''A. h. australis'' – Chapman, 1919: found in northern Colombia and northwestern Venezuela to eastern Peru and northern Bolivia Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane ...

Ecuadorian Cacique
The Ecuadorian cacique (''Cacicus sclateri'') is a species of bird in the family Icteridae. It is found in Colombia, Ecuador, and Peru, where its natural habitat is subtropical or tropical moist lowland forest. A fairly common bird with a wide range, the IUCN has rated it a "species of least concern". Description The male Ecuadorian cacique grows to a length of about , with the female being a little smaller. The plumage of both sexes is entirely black, the beak is whitish, long and pointed, and the iris is blue in adults and brown in juveniles. This bird can be distinguished from the otherwise similar solitary cacique (''Cacicus solitarius'') because that species is larger, has a darker-coloured iris and spends more time in undergrowth and near the ground and less time in trees. Also similar is the red-rumped cacique (''C. haemorrhous''), but it reveals its bright red rump patch when in flight. This bird has a number of noisy calls, including a repeated "péach-yo" and "péach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...
