How does Tiresias describe the behavior of birds when providing omens this time?

Tiresias, the blind prophet in Sophocles' Antigone, describes the behavior of birds in a way that reflects the turmoil and chaos that is unfolding in Thebes. By stating that the birds are flying erratically and creating chaos, Tiresias emphasizes the unnatural state of affairs in the city, indicating that there is disorder and bad omens surrounding the events taking place. This erratic behavior of birds serves as a metaphor for the disarray within the society and the consequences of the actions taken by characters like Creon and Antigone. Such chaotic signs suggest that the gods are displeased, reinforcing the idea that human actions have significant repercussions in the larger order of the universe. This aligns with the overall theme in the play about the tension between divine law and human law, indicating that ignoring divine will will lead to chaos and suffering.
