'fabled bird' is the definition.
'roc' can be an answer for 'bird' (mythological bird of prey). I'm not certain of the 'fabled' bit.

(Other definitions for roc that I've seen before include "Large bird of legend" , "Legendary air carrier" , "Mythical bird; sounds like boulder" , "Legendary flier" , "Fabulous giant bird of Eastern legend" .)
