What's fascinating is that the warning calls of other bird species seem to be understood by Parrots, too. I have a Rainbow Lorikeet and a Rose-Breasted Cockatoo that moved in along with the wife after we married - The Lorikeet is extremely animated, and the Cockatoo (a rescue) extremely timid. The Lorikeet has learnt to mimic the warning calls of local Sulphur-Crested Cockatoos, Noisy Minors, Common Mynahs. Occasionally, in the dead of night, the Lorikeet would make little satisfaction chirps while he's preening himself. He'd also recall all the sounds he's learnt to date, sometimes including warning calls of other birds - which sends the poor Cockatoo into a frenzy each time.
