Seedeater
{{Unreferenced, date=December 2007 The seedeaters are a form taxon of seed-eating passerine birds with a distinctively conical bill. Most are Central and South American birds that were formerly placed in the American sparrow family (Passerellidae), but are now known to be tanagers (Thraupidae) closely related to Darwins finches. Indeed, some of the birds listed here seedeaters are closer to these "finches", while the more "true" seedeaters form a clade with some tanagers. A few "atypical" seedeaters are closely related to certain tanagers, many of which (such as the flowerpiercers) have peculiarly adapted bills. In addition, there are some African passerines called seedeaters. They belong to the serin genus (''Serinus'') of the true finch family (Fringillidae), but might need to be separated with their closest relatives in ''Crithagra''.

Oryzoborus
''Sporophila'' is a genus of Neotropical birds in the tanager family Thraupidae. The genus now includes the six seed finches that were previously placed in the genus ''Oryzoborus''. They are relatively small with stubby, conical bills adapted for feeding on seeds and alike. Most species are strongly sexually dimorphic, and while "typical" adult males often are distinctive, female and immatures of both sexes can be very difficult (in some species virtually impossible) to identify to exact species. Females of at least some of these species have different ultraviolet colours, which can be seen by birds, but not humans. Female-like (paedomorphic) males apparently also occur, at least in some species. Taxonomy and species list The genus ''Spermophila'' was introduced by the English naturalist William John Swainson in 1827. The type species was subsequently designated as Temminck's seedeater (''Sporophila falcirostris'') by George Robert Gray in 1841. As the genus name ''Spermophila'' ...

Catamenia (bird)
''Catamenia'' is a genus of atypical seedeaters. Formerly placed in the Emberizidae, they are now placed in the tanager family Thraupidae. These species are found in more open areas in the Andes and the adjacent lowlands. Males are mainly gray; females are brownish and streaked. Both sexes have a distinctive chestnut . Taxonomy and species list The genus ''Catamenia'' was introduced in 1850 by the French naturalist Charles Lucien Bonaparte. The name is from the Ancient Greek ''katamēnia'' meaning "menstrual" or "menstruous". The type species was designated by the English zoologist George Robert Gray as the band-tailed seedeater in 1855. The genus now contains three species. This genus was traditionally placed with other seed-eating birds in the family Emberizidae. A series of molecular phylogenetic studies published in the first decade of the 21st century found that many genera in Emberizidae were more closely related to the fruit eating birds in the family Thraupidae.

Amaurospiza
''Amaurospiza'' is a genus of birds in the cardinal family Cardinalidae. Taxonomy and species list The genus ''Amaurospiza '' was introduced by the German ornithologist Jean Cabanis in 1861 with Cabanis's seedeater as the type species. The name is derived from the Ancient Greek ''amauros'', meaning "dusky", and (), a catch-all term for ''finch''-like birds. This genus was formerly included in the tanager family Thraupidae. It was moved to the cardinal family Cardinalidae based on a molecular phylogenetic study published in 2007. The genus contains four species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ...: References Seedeaters Bird genera Taxonomy articles created by Polbot {{Passeroidea-stub ...

True Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

Tanager
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euneornis
The orangequit (''Euneornis campestris'') is a species of passerine bird in the tanager family Thraupidae and is the only member of the genus ''Euneornis''. It is endemic to Jamaica where its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest. Breeding The Orangequit's breeding season is between the months of April and June. The species will build nests out of grass and plant fiber and place them in trees almost six meters above the ground. The female will typically lay 2-4 eggs at a time and will incubate. The appearances differs according to their sex and age. Taxonomy The orangequit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Motacilla campestris''. Linnaeus based his description on the "American Hedge-Sparrow" that George Edwards had described and illustrated in his 1750 work, ''A Natural History of Uncommon Birds'', fr ...

Loxigilla
''Loxigilla'' is a genus of passerine birds in the tanager family Thraupidae. The two species are both endemic to the Lesser Antilles. Taxonomy The genus ''Loxigilla'' was introduced in 1831 by the French naturalist René Lesson. The type species was later designated as the Lesser Antillean bullfinch by George Robert Gray in 1855. The name is a combination of two genera introduced by Carl Linnaeus in 1758: ''Loxia'' for the crossbills and ''Fringilla'' for a group of finches. Although formerly placed with the buntings and New World sparrows in the family Emberizidae, molecular phylogenetic studies have shown that the genus is a member of the tanager family Thraupidae and belongs to the subfamily Coerebinae which also includes Darwin's finches. The genus contains two species, both endemic to the Lesser Antilles: The Greater Antillean bullfinch and Puerto Rican bullfinch were formerly placed in this genus, but are now placed in ''Melopyrrha ''Melopyrrha'' is a genus of pa ...

Form Taxon
Form classification is the classification of organisms based on their morphology, which does not necessarily reflect their biological relationships. Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known. Form taxonomy is restricted to fossils that preserve too few characters for a conclusive taxonomic definition or assessment of their biological affinity, but whose study is made easier if a binomial name is available by which to identify them. The term "form classification" is preferred to "form taxonomy"; taxonomy suggests that the classification implies a biological affinity, whereas form classification is about giving a name to a group of morphologically-similar organisms that may not be related. A "parataxon" (not to be confused with parataxonomy), or "sciotaxon" (Gr. "shadow taxon"), is a classification based on incomplete data: for instance, the larval stage o ...

Melanospiza
''Melanospiza'' is a genus of Neotropical birds in the tanager family Thraupidae. Taxonomy and species list The genus ''Melanospiza '' was introduced in 1897 by the American ornithologist Robert Ridgway with the Saint Lucia black finch as the type species. The name combines the Ancient Greek ''melas '' meaning "black" and ''spiza'' meaning "finch". Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, molecular phylogenetic studies have shown that the genus is a member of the tanager family Thraupidae and belongs to the subfamily Coerebinae which also contains Darwin's finches Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or t ....
