Heathcliff

Heathcliff is a character in the Once Upon a Time novel, "Red's Untold Tale". He was a talking crow, subservient to the wizard Knubbin.

Before the Curse
When Red and Peter go searching for Knubbin, they come across Heathcliff the crow, who Red swears is talking to her. Peter can't hear it, but that's because Knubbin wants this to be so, and Heathcliff asks for one of Red's crumpets. Red gives it to him in exchange for him leading her to the wizard's cottage, where he lives as Knubbin's pet. He obliges, and the next day the same thing happens. However, Knubbin abandons the cottage and presumably takes his pet crow with him.
