What kind of noises do quokkas make? No one knows, because no one's ever seen on of these things. Cockatiels, on the other hand, have lovely melodious voices capable of a range of sounds and songs. They're the John Williams of animals. No, strike that, they're hipper than that. They're the Skrillex of animals. Wait, less annoying than that. Look, the point is cockatiels can make a lot. of. sounds.
