List Of Birds

From Nwe

This page lists living orders and families of birds, class Aves.

Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate. The Sibley-Ahlquist taxonomy offers a different classification.

This article and the descendant family articles follow the taxonomy of the Handbook of Australian, New Zealand and Antarctic Birds (HANZAB) for families largely endemic to that region, and otherwise the Handbook of Birds of the World (HBW).

Paleognathae

The flightless and mostly giant Struthioniformes lack a keeled sternum and are collectively known as ratites. Together with the Tinamiformes, they form the Paleognathae (or “old jaws”), one of the two evolutionary "super orders."

Neognathae

Nearly all living birds belong to the super order of Neognathae— or 'new jaws'. With their keels, unlike the ratites, they are known as carinates. The passerines alone account for well over five thousand species.
