Along with dodos, the ichthy can also pick up lystros, compys, pegomastaxes, and jerboas, so if a pegomastax steals your stuff, starts running away and you have a ichthyornis on your shoulder, look directly at the pegomastax, then release the ichthy so it will pick up the pegomastax and slowly bite it to death, all while following you. After a while your ichthyornis will kill it, and the corpse will drop raw prime meat.
