Perdix

Perdix was the young nephew of Daedalus. The old master was jealous of the boy's genius which rivaled his own and one day, in a rage, caused his nephew to lose his balance and fall to his death. Athena saw what he had done and swore to make him pay, then and forever more for his part in the boy's death.

When Perdix died, Athena turned him into a small partridge. She then branded Daedalus with the image of a partridge for him crime.
