The Ichthyornis is a troublesome coastal bird that can steal food, eggs, and equipment, so stay alert during swooping attacks and recover anything it drops. To tame one, wait for it to land or leave the water, restrain it with a bola, carefully knock it unconscious, and feed it fish-based food or kibble while protecting your belongings. Once tamed, it serves as a shoulder mount that can hunt and retrieve small prey, harvest valuable fish resources, safely kill jellyfish for biotoxin, and improve food for taming certain creatures.
