Neoaves is a clade that consists of all modern birds (Neornithes or Aves) with the exception of Palaeognathae (ratites and kin) and Galloanserae (ducks, chickens and kin). [4] This group is defined in the PhyloCode by George Sangster and colleagues in 2022 as "the most inclusive crown clade containing Passer domesticus, but not Gallus gallus". [5]
Modern birds would have expanded from West Gondwana through two routes. One route was an Antarctic interchange in the Paleogene. The other route was probably via Paleocene land bridges between South America and North America, which allowed for the rapid expansion and diversification of Neornithes into the Holarctic and Paleotropics.

Ornithurae (meaning "bird tails" in Greek) is a natural group that includes modern birds and their very close relatives such as Ichthyornis and the hesperornithines.This clade is defined in the PhyloCode by Juan Benito and colleagues in 2022 as "the smallest clade containing Ichthyornis dispar, Hesperornis regalis, and Vultur gryphus".

Gaviiformes (/ ˈ ɡ æ v i. ɪ f ɔːr m iː z /) is an order of aquatic birds containing the loons or divers and their closest extinct relatives. Modern gaviiformes are found in many parts of North America and northern Eurasia (Europe, Asia and debatably Africa), though prehistoric species were more widespread.

They feed on insects, snakes, lizards, frogs, young birds, and rodents, with small amounts of plant food (including maize and beans). They often associate with grazing livestock, probably to take insects the animals disturb.

The finger bones of the Teratornis were fused as in all modern birds; however, part of the index finger forms a shelf which aided in bearing the load of long and stout primaries, enabling the bird to utilize strong upcurrents in flight. Their legs were similar to an Andean condor's, but stouter, and the feet could hold prey for tearing off ...
