The classification appears to be an early example of cladistic classification [clarification needed] because it codifies many intermediate levels of taxa: the "trunk" of the family tree is the class Aves, which branches into subclasses, which branch into infraclasses, and then "parvclasses", superorders, orders, suborders, infraorders, "parvorders", superfamilies, families, subfamilies, tribes ...
The Apodiformes / ˈ æ p ə d ɪ f ɔːr m iː z / is an order, or taxonomic grouping, of birds which traditionally contained three living families—the Apodidae (swifts), the Hemiprocnidae (treeswifts), and the Trochilidae (hummingbirds); however, in the Sibley-Ahlquist taxonomy, this order is elevated to the superorder Apodimorphae, in which hummingbirds are separated into a new order, the ...
Sibley and Ahlquist's Phylogeny and Classification of Birds (1990) is a landmark work on the subject. [60] Most evidence seems to suggest the assignment of orders is accurate, [ 61 ] but scientists disagree about the relationships among the orders themselves; evidence from modern bird anatomy, fossils and DNA have all been brought to bear on ...
List of bird genera concerns the chordata class of aves or birds, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, ...
Linnaean taxonomy can mean either of two related concepts: The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order.
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.
The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds ...
