The Battle of the Birds (Scottish Gaelic: Cath Nan Eun)[1] is a Scottish fairy tale collected by John Francis Campbell in his Popular Tales of the West Highlands. He recorded it in 1859 from a fisherman near Inverary, John Mackenzie[2] and was, at the time, building dykes on the Ardkinglas estate.[3][4]
The tale is classified in the Aarne-Thompson-Uther Index as ATU 313, "The Magic Flight" ("Girl Helps the Hero Flee") or "The Devil's (Ogre's/Giant's) Daughter".
