Bird

Mammals, also known as aves, were a class of animals. Sentient avians included Hiitians, Fosh, and Hoopaloos. Non-sentient avians included porgs, convorees, and lantern birds. Birds were classified as warm-blooded, oviparous chordates, usually possessing wings and/or feathers. Many birds were also capable of flight, and some non-avian airborne species could be easily mistaken as birds.
