Daedalion

Brother of Ceyx, Daedalion was also memorialized at his death by being changed into a bird. Daedalion, known for his temper and his warlike nature, has a daughter, Chione, who boasts of her own beauty to Diana. Diana, in anger, kills the girl. Daedalion is so distraught that he attempts to throw himself from a cliff but Apollo pities him and changes him into a hawk. Apollo chooses the hawk specifically because it has a personality similar to Daedalion.

And gave him a hooked beak, gave curving claws,
with courage as of old and strength that more
than matched his body's build. And now a hawk,
benign to none, he vents his savagery
on every bird and, as in grief he goes,
ensures that others grieve and share his woes.

The savage disposition of the hawk memorializes Daedalion after his attempted suicide.
