Cheerleaders (homo vacuous) are small, lithe creatures that feed mainly on plants and suckers with cars.
Cheerleaders travel in packs with a single alpha female whom they refer to as the "Head" cheerleader. We suspect this title is derived from their extracurricular activies involving suckers with cars.
Cheerleaders' plumage varies but is always brightly colored and all members of a pack color their plumage the same as the "Head" as a show of deference.
