Pyrrhura Frontalis -Cerrito, Rio Grande Do Sul, Brasil-8
''Pyrrhura'' (Greek Red/Fire Tail) is a genus of parrots in the Arini tribe. They occur in tropical and subtropical South America and southern Central America (Panama and Costa Rica). Most are restricted to humid forest and adjacent habitats, but one species, the blaze-winged parakeet, prefers deciduous or gallery woodland, and another, the Pfrimer's parakeet, is restricted to dry regions. Some species are highly endangered. Depending on the species, the total length range from . All have long, pointed tails, a mainly green plumage, and a relatively narrow, dark greyish to white eye-ring. Many have scaly or barred chest-patterns and a whitish, pale grey, buff or reddish ear-patch. They typically move around in small, noisy flocks, flying swiftly at or below canopy level. Once settled in a tree they tend to be silent (especially if aware of danger) and difficult to spot. They nest in a tree-crevice. Some species are popular in aviculture, where they are commonly referred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green-cheeked Parakeet
The green-cheeked parakeet or green-cheeked conure (''Pyrrhura molinae'') is a small parrot of the genus ''Pyrrhura'', which is part of a long-tailed group of the New World parrot subfamily Arinae. The term ''conure'' is often used for this parrot and its relatives in aviculture. It is native to the forests of Central and South America. Description The green-cheeked parakeet is typically long and weighs 60 to 80 g. It is mainly green, with a brown/black/grey crown, white periophthalmic rings, green cheeks, blue primary wing feathers, a grey beak, and a long, mainly maroon tail. It has short transverse striations on its breast and a red abdominal area. Males and females have a mostly identical external appearance. The only truly verifiable way to identify the gender of a green-cheeked parakeet is through a DNA test. Taxonomy The green-cheeked parakeet has six subspecies:Forshaw (2006). plate 85. * ''Pyrrhura molinae'', (Massena & Souance 1854) ** ''P. m. australis'', Todd 1 ...

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Blaze-winged Parakeet
The blaze-winged parakeet (''Pyrrhura devillei''), more commonly known as the blaze-winged conure in aviculture, is a species of parrot found in wooded habitats in the Pantanal region of Brazil, Bolivia and Paraguay. It remains locally fairly common, but has suffered due to extensive habitat destruction within its relatively small range, and has therefore been uplisted to near-threatened by BirdLife International in 2009. The type specimen is labelled Bolivia, but due to shifting borders it is now believed to be from Paraguay. It has often been considered a subspecies of the maroon-bellied parakeet based on apparent hybrids from Paraguay, but – as far as known – the two generally maintain their integrity, and are recent sources are undecided on whether to treat them as one species or two. They resemble each other, but the blaze-winged parakeet has a dusky crown and red "shoulder" and underwing coverts. References * Collar, N. J. (1997). Blaze-winged Parakeet (Pyrrhura deville ...

Maroon-bellied Parakeet
__NOTOC__ The maroon-bellied parakeet (''Pyrrhura frontalis'') is a small parrot found from southeastern Brazil to north-eastern Argentina, including eastern Paraguay and Uruguay. It is also known as the reddish-bellied parakeet, and in aviculture it is usually referred to as the maroon-bellied conure, reddish-bellied conure or brown-eared conure. Taxonomy It has been suggested that the reddish-bellied parakeet should include the blaze-winged parakeet (''P. devillei'') as a subspecies based on intermediate specimens from Paraguay. But such hybrids are not common in the wild and the two populations generally maintain their integrity; recent sources are undecided on whether to treat them as one species or two. Description These birds range from 25 to 28 cm (10–11 in), and are primarily green, with a maroon patch on the belly, a "scaly" yellow-green-barred breast and sides of neck, a whitish ear-patch often tinged brown, and a maroon undertail.

Ochre-marked Parakeet
The ochre-marked parakeet (''Pyrrhura cruentata'') is a species of parrot native to Brazil. It is also known as blue-throated parakeet and red-eared conure in English and ''tiriba-grande'', ''tiriba'', ''cara-suja'' and ''fura-mato-grande'' in Portuguese. It is listed as Vulnerable (VU) on the IUCN Red List. Description This colourful parakeet is a predominantly green bird with conspicuous red patches on its belly, rump, and shoulder and before, below and behind the eye. The crown is dark brown to blackish, becoming mottled on the nape of the neck, and there is a broad, bright blue bib on the chest, extending thinly around the back of the neck to form a faint collar. The outer primaries are blue, and the tail is olive-green above, and brownish red below. Habitat It inhabits the canopy of lowland humid forest and edge, occasionally up to 960 meters. It has also been recorded in small clearings and selectively logged forest, and persists (or at least persisted) in agricultural are ...

American Ornithologists' Union
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.

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-eared Parakeet
The white-eared parakeet or maroon-faced parakeet (''Pyrrhura leucotis'') is a small parrot belonging to the genus ''Pyrrhura''. As here defined, it is endemic to Atlantic Forest in eastern Brazil. The Venezuelan, grey-breasted and Pfrimer's parakeets were formerly classed as subspecies of this bird but are increasingly treated as separate species. Description It is 21–22 centimetres long. The plumage is mostly green. The chest has dark grey and whitish scaling on a green background, and the rump and belly are maroon. The face and throat are dark maroon, the forehead is bluish and there is a whitish ear-patch. The long, graduated tail has a red underside. The bird has a sharp call which is repeated three or four times. The grey-breasted parakeet is very similar but is proportionally larger-headed, has a longer bill with a deeper mandible, lacks blue to the forecrown (as do the occasional white-eared parakeet), and its breast is entirely scaled dark grey and whitish (little or ...

Painted Parakeet
The painted parakeet (''Pyrrhura picta''), more commonly known as the painted conure in aviculture, is a species of bird in the family Psittacidae, the true parrots. Its taxonomy is highly complex, and has undergone significant changes in recent years. As here defined, it is restricted to forests in northern South America (north of the Amazon River) and Panama. Some of the taxa here included in the painted parakeet are highly endangered. Taxonomy and distribution Traditionally, the painted parakeet included the Santarém parakeet (''P. amazonum''), Bonaparte's parakeet (''P. lucianii'') and rose-fronted parakeet (''P. roseifrons'') as subspecies. Following a review in 2002, it was recommended treating these as separate species.Joseph, L. (2002). ''Geographic variation, taxonomy and distribution of some Amazonian Pyrrhura parakeets.'' Ornitologia Neotropical 13(4): 337-363. In 2006, a study based on mtDNA confirmed that the "traditional" painted parakeet was polyphyletic, as ''P. ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
