Apart from their eyes, a striking feature of many ornitheres species is their bird-like feathers. These range from the downy plumes present in other saucebacks to complex, aerodynamic flight feathers unique to them. Many ornitheres have flight feathers, typically located on the legs (remiges) and tail (rectrices), forming "leg-wings" and a tail fan, respectively. Biats also have flight feathers attached to their ears (canard feathers). Similar to [[Wikipedia:Bird|birds]], these flight feathers are used for various forms of aerial locomotion, including fluttering, gliding, and flight.

In biats, feathers are organized into tracts, or pterylae, rather than covering the whole body. The flight feather tracts are the caudal (tail fan), left and right alar (wings), left and right aural (ears), and left and right pulmonary (upper tail); some of these are absent in more derived species. The body feathers are the dorsal tract (a U shape on the back that meets in front of the sauce plate), ventral tract (a U shape on the underbelly that meets at the gastralium), femoral tract (wing coverts; not to be confused with a ~~bird’s~~ femoral tract), capital tract (head and neck), and buccal tract (front of face). The buccal tract is usually split from the capital tract by the oral ring, but in certain quails, it instead covers the cheeks and throat.<ref>[[Krikrees#Feathers]]</ref>
