Augury is the practice from ancient Roman religion of interpreting omens from the observed behavior of birds. When the individual, known as the augur, interpreted these signs, it is referred to as "taking the auspices". "Auspices" literally means "looking at birds", and Latin auspex, another word for "augur", literally means "one who looks at birds". Depending upon the birds, the auspices from the gods could be favorable or unfavorable. Sometimes politically motivated augurs would fabricate unfavorable auspices in order to delay certain state functions, such as elections. Pliny the Elder attributes the invention of auspicy to Tiresias the seer of Thebes, the generic model of a seer in the Greco-Roman literary culture.
