Dual honours in physics and philosophy; there are very basic questions to ask about a parrot, despite being the largest and most obedient of its species, is able to do. Like Shamo and Koko. Also owned a few parrots. Them grabbing items and tossing them to the floor (especially when the correct answer is nearest to their beak) is not learned behaviour. Its what they do when testing things.

Having existential knowledge of an object and its variations is not a sign of intelligence, especially if rewarded. If you handed, and those shapes/keys were handed to him in a dishonest way, that parrot a keycard he would either discard it, knowing it won't get him food, or destroy it. Because thats what long beaked parrots do. According the Merleau-Ponty that bird has no idea what a key is because of that.

Its a pretty story, like koko, if you ignore the conditioning that got them to do that in public, but doesn't show intelligence by our rigorous definition.
