This reminds me of Ovid's story of Coronis. Coronis was a mortal woman who was a lover of Apollo but was unfaithful to him. The raven, which was then a white bird, heard of her infidelity and reported it to Apollo. Apollo killed Coronis and punished the raven by turning it black. Coronis herself became the constellation Corvus (the Crow) after her death.
Note that far-darting Apollo was the god of, among other things, epidemic disease. By some accounts, Coronis was the mother of Apollo's son Aesculapius, whose staff and serpent has become a universal symbol of medicine, appearing for example on the logo of the WHO.
