Is there anyone out there who ever witnessed a parrot being predated by a bird or any other animal? I try to make an inventory of predators of this kind.

In Mexico, man is the biggest predator of the Yellow-headed Parrots. They have almost been extirpated in Mexico for the pet trade. This probably isn't the info you were looking for, but thought I would throw it in.

Not only in Mexico but Worldwide the declining of habitats by human interference and the capturing of parrots for live trade are the two main reasons that makes man the biggest predator on wild parrots!
So you're right to throw this in!
The main reason why I am looking for more 'other than human' predadors is to make other birdkeepers aware that parrots should no longer be caught for international trade and no longer be imported in to Western countries.
By publishing facts (unknown or unfamiliar facts to the average birdkeeper) about natural predation on parrots combined with widely known human interference as mentioned before, I might just keep a few extra birdkeepers from buying an imported parrot.
