This is a list of the taxonomic orders in the subclass Neornithes, or modern birds. The list of birds gives a more detailed summary of these, including families.
SUBCLASS NEORNITHESPaleognathae:
Struthioniformes, Ostrich, emus, kiwis, and allies
Tinamiformes, tinamous
Neognathae:
Anseriformes, waterfowl
Galliformes, fowl
Gaviiformes, loons
Podicipediformes, grebes
Procellariiformes, albatrosses, petrels, and allies
Sphenisciformes, penguins
Pelecaniformes, pelicans and allies
Ciconiiformes, storks and allies
Phoenicopteriformes, flamingos
Falconiformes, falcons, eagles, hawks and allies
Gruiformes, cranes and allies
Charadriiformes, gulls, button-quail, plovers and allies
Pteroclidiformes, sandgrouse
Columbiformes, doves and pigeons
Psittaciformes, parrots and allies
Cuculiformes, cuckoos, turacos, hoatzin
Strigiformes, owls
Caprimulgiformes, nightjars and allies
Apodiformes, swifts and hummingbirds
Coraciiformes, kingfishers
Piciformes, woodpeckers and allies
Trogoniformes, trogons
Coliiformes, mousebirds
Passeriformes, passerines
Note: This is the traditional classification (the so-called Clements order). A radically different classification based on molecular data has been developed (the so-called Sibley-Monroe classification or Sibley-Ahlquist taxonomy). This has influenced taxonomical thinking considerably, with the Galloanserae proving well-supported by recent molecular, fossil and anatomical evidence.[citation needed] With increasingly good evidence, it has become possible by 2006 to test the major proposals of the Sibley-Ahlquist taxonomy. The results are often nothing short of astounding, see e.g. Charadriiformes or Caprimulgiformes.
[edit] Extinct bird orders
A wide variety of bird groups became extinct during the Mesozoic era and left no modern descendants. These include the orders Archaeopterygiformes, Confuciusornithiformes, toothed seabirds like the Hesperornithes and Ichthyornithes, and the diverse subclass Enantiornithes ("opposite birds").
