It’s not always oil that we spill into the ecosystem. Every now and then a pet cockatoo is let loose or escapes, joins a wild flock, and teaches the natives how to speak. The phenomenon accounts for “numerous” reports by Australians who think they are hearing voices. According to researchers, in the rural regions the new talkers will likely lose their speaking abilities, but in the big cities it’s probable that cockatoos will hone those skills due to contact with humans.
