Sony just released some more details regarding Final Fantasy XI's new Chocobo breeding program. Included are descriptions of some of the various breeds of the giant birds most adventurers use as mounts for quick travel.
Destrier
Originally bred for armored combat in the nation of San d'Oria, these black Chocobos are capable of wearing heavy armor. However, since heavily armored cavalry have gone out of fashion among the realms of Vana'diel, these birds have become extremely rare... almost completely disappearing from the lands. While purebred Destriers are no longer found anywhere, their legacy occasionally crops up with the birth of extraordinarily rare black Chocobos.
Courser
Easily the most common breed of Chocobo, these animals have become the defacto mount of choice for the military of San d'Oria. While Coursers are most frequently yellow in color, red versions have been seen on rare occasions.
