According to Senchas Mor the third most popular pet in Pre-Christian Ireland after cats and dogs was the crane (Peata Corr). In pagan times, the druids saw cranes as the heavenly transporters of the human soul to isles in the west. Some suggest fires were lit under a migration flight path of the now extinct in Ireland, Grús at Dun Aonghasa. The fort is associated with the Aengus the foster son of Midir who is said to have owned three mystical magical cranes.
