My grandfather, an owner of an African Grey Parrot, died in his early 80s. His final years were marked by lung disease and a hacking cough. After he died, it was always a bit weird to visit my grandmother as, for the remainder of his life, the parrot (whose name I cannot recall) would hack away in precise imitation of the cough which killed our old grandpa. Parrots truly are unlike any other pet.
