Knowra Bird taxonomy Bird taxonomy Bird taxonomy classifies birds into named groups and arranges those groups to reflect evolutionary relationships. It combines formal nomenclature with evidence from anatomy, behavior, fossils, and genetic data.
Biological classification : The organization of organisms into named groups based on shared characteristics and relationships. Bird taxonomy applies this general system to birds.
Molecular phylogenetics : The reconstruction of evolutionary relationships using DNA, RNA, or protein sequences. Genetic comparisons have reordered many bird groups once classified mainly by appearance.
Neognathae : The major bird clade containing most living bird species, including songbirds, waterfowl, and birds of prey. It encompasses nearly all living birds outside the palaeognath lineages.
Carl Linnaeus : The Swedish naturalist who established the binomial system in the tenth edition of Systema Naturae. His naming framework underlies the scientific names assigned to birds.
Conservation status : An assessment of a species’ risk of extinction, often expressed through categories such as threatened or least concern. Splitting or merging bird species can change which populations receive risk assessments.
Binomial nomenclature : A system that gives each species a two-part scientific name consisting of genus and specific epithet. It supplies the standard scientific names used for bird species.
Comparative anatomy : The study of similarities and differences in anatomical structures among organisms. Skeletal and soft-tissue traits have long supplied evidence for grouping birds.
Palaeognathae : A major bird clade that includes ostriches, rheas, emus, kiwis, and tinamous. Its unusual distribution and flightlessness have made its relationships a central taxonomic problem.
John James Audubon : A French-American artist and naturalist known for The Birds of America. His illustrations and field observations helped document North American bird diversity.
Endemic species : A species native to and restricted to a particular geographic region. Taxonomic recognition can reveal bird lineages with very small ranges.
