Manipulating Parrots

Parrots become annoyed, according to Irene Pepperberg, a visiting professor at MIT's Media Lab who studies African grey parrots.

Pepperberg described an experiment where the parrots refused to retrieve a nut that was hanging from a string. One of the birds, Alex, who knows over 1,000 words and can form simple sentences, repeatedly asked the trainer to get the nut for him.

He and the other birds became agitated when their requests were ignored. Pepperberg said that this ability to manipulate others using language previously was only thought to be a human trait.

Could be much more in selecting 'correct' food for our birds. They know what they want!
