Agelasticus
''Agelasticus'' is a genus of birds in the New World blackbird and oriole family Icteridae. They have slender forms and narrow bills. Male plumage is mostly or entirely black while that of females is generally brown and streaky. Females are responsible for building the nest, unlike some of their close relatives. The genus occurs only in South America.Fraga, R. & Bonan, A. (2017). New World Blackbirds (Icteridae). In: del Hoyo, J., Elliott, A., Sargatal, J., Christie, D.A. & de Juana, E. (eds.).

Unicolored Blackbird
The unicolored blackbird (''Agelasticus cyanopus'') is a species of bird in the family Icteridae. Found in Argentina, Bolivia, Brazil, and Paraguay, its natural habitat is swamps and nearby grassland. It is a fairly common bird and the International Union for Conservation of Nature has rated it a "least-concern species". Description The male unicolored blackbird is befitting of its name, with entirely glossy black plumage and dark eyes. However, the species exhibits sexual dimorphism; the female is streaked brown and black with a yellow belly streaked with brown. The face has a dark mask and the wings are reddish-brown edged with black. Females from the lower Amazon region and southeastern Brazil have a generally duller colouration with less rufous wings and less yellow underparts. The legs and the iris are black and the bill is long and sharply pointed. The male could be confused with the velvet-fronted grackle or the chopi blackbird. Its call of this bird is a loud "tchew-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agelasticus Xanthophthalmus
The pale-eyed blackbird (''Agelasticus xanthophthalmus'') is a species of bird in the family Icteridae. It is found in Ecuador and Peru where its natural habitat is swamps. An inconspicuous bird of very local occurrence, it was first described in 1969 by American ornithologist Lester L. Short. Description The adult pale-eyed blackbird is entirely black in both sexes. It has white or pale buff coloured irises to its eyes which are very distinctive and distinguish it from other black birds found in the area such as the velvet-fronted grackle and the shiny cowbird which have dark eyes. Juveniles and immature birds are brownish-black with underparts streaked with yellow or buff. The call is a loud metallic "tew-tew-tew-tew" similar to that of a black-capped donacobius. It is usually sung from the top of a shrub. Distribution and habitat The pale-eyed blackbird is found in a restricted area of eastern Peru and Ecuador. Its habitat is marshy areas round lagoons and oxbow lakes and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-winged Blackbird
The yellow-winged blackbird (''Agelasticus thilius'') is a species of bird in the family Icteridae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay. The species' natural habitats include marsh In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants.Keddy, P.A. 2010.

Adult males are black-plumaged except for bright yellow epaulets and the corresponding feather tracts on the underside of the wing. Adult females are brown and streaky, while immature males are similar to females in plumage, but with the addition of the adult male's yellow wing patches.

Icteridae
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. Etymology The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the - ''íkteros'' via the . Relationship to other species This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, Quiscalus, grackles, cowbirds, oropendolas, and cacique (bird), caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush (bird), thrush) or to the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the ''Journal für Ornithologie'' in 1853''.'' Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum, Berlin, Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Jean Cabanis
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
