This category lists orders of birds (ending in "-formes") as categories, and pages dealing with certain (non-taxonomic) groups of birds. The first section links to categories listing lower taxonomic levels in birds. In the second section, higher categories such as superorders, and basal groups are listed.
The ratites are mostly large and long-legged, flightless birds, lacking a keeled sternum. Traditionally, all the ratites were place in the order Struthioniformes . However, recent genetic analysis has found that the group is not monophyletic, as it is paraphyletic with respect to the tinamous , so the ostriches are classified as the only ...
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 ...
Unlike Category:Prehistoric birds, which covers all prehistoric avialans, even non-neornithines, this category only covers neornithines. Category:Prehistoric birds is therefore not a descendant of Category:Birds. For individual species of birds, see the subcategories, particularly category:Birds by classification and category:Birds by country.
In 1901, Robert Ridgway wrote in the introduction to The Birds of North and Middle America that: There are two essentially different kinds of ornithology: systematic or scientific, and popular. The former deals with the structure and classification of birds, their synonymies, and technical descriptions.
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, ...
Birds (class Aves) – winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. There are around 10,000 living species, making them the most varied of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic, to the Antarctic.
dietary classification terms (-vores) Birds may be classified by terms related to the types of foods they forage for and eat. [141] The -vore suffix is derived from the Latin vorare, meaning 'to devour'. Equivalent adjectives can be formed through use of the suffix -vorous. [142] For example, granivore (n.) / granivorous (adj.). Generally ...
