While walking through the mysterious Foggy Swamp, Aang, Katara, and Sokka stopped to make camp. As Sokka tried to convince the group that it was just a normal swamp, a nearby screech from this bird frightened them, and they huddled together to quell each other's fear.
The screeching bird has fluffy white or light gray feathers covering its body. Its eyes and beak are almost hidden by its pudgy face; the eyes appear beady and dark beneath the head feathers. Though its beak appears tiny when closed, it can open wide to emit a loud shriek that sounds like a woman screaming.
The bird does not have any known real world connections beyond its appearance as a bird.
