Birds (flying, soaring) – Most of the approximately 10,000 living species can fly (flightless birds are the exception). Bird flight is one of the most studied forms of aerial locomotion in animals. See List of soaring birds for birds that can soar as well as fly. Townsends's big-eared bat, (Corynorhinus townsendii) displaying the "hand wing"
The colugos, Petauridae, and Anomaluridae are gliding mammals which are similar to flying squirrels through convergent evolution, although are not particularly close in relation. Like the flying squirrel, they are scansorial mammals that use their patagium to glide, unpowered, to move quickly through their environment.

Colugos are proficient gliders, and thought better adapted for flight than any other gliding mammal. They can travel as far as 70 m (230 ft) from one tree to another without losing much altitude, [10] with a Malayan colugo (Galeopterus variegatus) individual having been observed traveling about 150 m (490 ft) in one glide.

The sugar glider is a sexually dimorphic species, with males typically larger than females. Sexual dimorphism has likely evolved due to increased mate competition arising through social group structure; and is more pronounced in regions of higher latitude, where mate competition is greater due to increased food availability.
Patagia on a flying squirrel. To assist gliding, some mammals have evolved a structure called the patagium. This is a membranous structure found stretched between a range of body parts. It is most highly developed in bats. For similar reasons to birds, bats can glide efficiently. In bats, the skin forming the surface of the wing is an extension ...
The feathertail glider (Acrobates pygmaeus), also known as the pygmy gliding possum, pygmy glider, pygmy phalanger, flying phalanger and flying mouse, [3] is a species of marsupial native to eastern Australia. It is the world's smallest gliding mammal and is named for its long feather-shaped tail.
A model was used to test the viability of a handwings-only glider and found it ineffective as an actual gliding animal.
