What Are Examples of Animals in the Class Aves?
Some examples of animals found in the class Aves are ducks, hummingbirds, songbirds, woodpeckers, owls and raptors. The class of Aves is composed of birds. It was first developed in 1676 by John Ray and Francis Willughby, but the current system was devised by Carolus Linnaeus in 1758.

There are 29 orders, or sub-groups, of this class, which includes more than 10,000 known species. Some of the more common examples include:
- Anseriformes - ducks, swans and geese
- Falconiformes - falcons, eagles and hawks
- Galliforomes - fowl such as chickens, turkeys and pheasant
- Struthioniformes - flightless birds including emus, ostriches and kiwis
- Passeriformes - perching birds and songbirds such as sparrows, larks, crows and swallows
