The Bird's City
The creation of the bird's new city creates the imagery of thousands upon thousands of birds performing duties swiftly and accurately that enable the city to be created in a matter of time so short it astounds Peisetaerus. It reveals the industriousness and the seemingly unending supply of birds for the task.
Visitors
Aristophanes creates waves of visitors that come to see Peisetaerus as he is performing a religious ceremony to sacrifice to the birds. The imagery creates a comical sequence that interrupts a sacred ceremony with the pleading and seemingly small needs of people and their reports.
The Garden
Tereus describes how the birds feed on different trees and flowers in the gardens they live in. The imagery he creates has a double meaning of beauty but also of sexual desire being fulfilled as Peisetaerus and Euelpides don't have an adult-mind for sexual feelings.
Negotiations
Aristophanes creates a negotiation between Poseidon, Heracles, Triballians and Peisetaerus where it seems they have come to crush him. But, instead the imagery shows how willing the gods are to concede all of their power and rights simply because they are hungry, and Triballians, who is the god of the barbarians, appears to be incapable to speaking anything other than gibberish.
