abstract:Ornithomancy (modern term from Greek ornis "bird" and manteia "divination"; in Ancient Greek: οἰωνίζομαι "take omens from the flight and cries of birds") is an Ancient Greek practice of reading omens from the actions of birds, equivalent to the Augury employed by the ancient Romans. Although it was mainly the flights and songs of birds that were studied, any action could have been interpreted to either foretell the future or relate a message from the gods.
