I've heard of Amazons using their molted feathers (or pencils or other similar objects) to preen with, but I'd never seen it before. Very clever.
Has anyone else witnessed their parrots using tools before? Iggy and Ollie frequently scratch their heads on their perches or the cage bars, but that doesn't really constitute tool use so much as use of the environment.
