When Eochaid married Etain, Etain produced one child, a daughter. The king was furious at this and ordered that she be taken to a pit and killed. The men who were to carry out the king's wishes set her free and she fled to the cow sheds of the King of Tara. There her name became Mes Buachalla the cowherds fosterling. One day a bird appeared and declared that she would become pregnant by him, and that the child was never to kill birds. He also said the child's name was to be Conaire. Thus Conaire was born, the son of a bird man. This link between hero and birds is quite common in Irish Mythology, the Children of Lir being another example.
