Metamorphoses Book 8: Perdix
Daedalus was burying Icarus when he saw a partridge nearby taking joy in his sorrow. The partridge had once been Perdix, Daedalus' nephew. Daedalus was supposed to train the boy, but he'd gotten jealous when the kid invented first the saw, and then the mathematical compass. So in his rage, Daedalus threw the boy from the Acropolis and killed him. Athene transformed Perdix into a partridge, a bird that remembers his far fall from the sky and keeps close to the ground as a result.
