Chocobo
Chocobos are large and (generally) flightless birds native to several worlds throughout the Web of Worlds. With horses, they are one of the most common domesticated animals, used primarily as riding and war beasts. The Esper and Crystal dimensions are known for their profusion of chocobos of various breeds. Chocobos are also found in the Merge and Kuvalla dimensions, and are also native to the world of Alter-Mana in the Alter Dimension. Grimfowl, a related species, are found in the Dragon Dimension, as well as on the world of Alter-Dragon in Alter.
