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.

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Diglossa (bird)
''Diglossa'' is a genus in the family Thraupidae. They are commonly known as flowerpiercers because of their habit of piercing the base of flowers to access nectar that otherwise would be out of reach. This is done with their highly modified bill, which is typically upswept, with a hook at the tip. Most members of the genus ''Diglossa'' are found in highlands of South America (especially the Andes), but two species are found in Central America. Taxonomy and species list The genus ''Diglossa'' was introduced by the German naturalist Johann Georg Wagler in 1832 with the cinnamon-bellied flowerpiercer (''Diglossa baritula'') as the type species. The genus name is from the Ancient Greek ''diglōssos'' meaning "double-tongued" or "speaking two languages". The genus now includes 18 species. * Golden-eyed flowerpiercer, ''Diglossa glauca'' * Bluish flowerpiercer, ''Diglossa caerulescens'' * Masked flowerpiercer, ''Diglossa cyanea'' * Indigo flowerpiercer, ''Diglossa indigotica'' * ...
