As Blu and his family head towards the Amazon, they enlist some Rhea to carry them for a short distance. Tiago calls for his steed to go faster, but Blu calls for his to go slower, accidentally covering her eyes, which makes her laugh. Later on, a Rhea dances in the auditions for Nico and Pedro's show, but tangles herself up in her long neck.

Individual and Flock Behavior

The Greater Rhea is a silent bird except during mating season, when they make low booming noises, and as chicks, when they give a mournful whistle. During the non-breeding season they will form flocks of between 10 and 100 birds. When in flocks, they tend to be less vigilant, but the males can get aggressive towards other males. When chased they will flee in a zig-zag pattern, alternately raising one wing then the other. These flocks break up in the winter in time for breeding season.
