Behold the power of... birds
Being a bird brain has all but lost its sting in light of the most recient discovery in avian intellegence.
Previously, scientist had seen birds using problem solving to get food, and even tools (ravens, woodpeckers, and vultures all have done it) but now they've seen crows not merely using a ready made tool from the environment, but CREATING hooks to get food. This is not merely in the lab. In the wild, New Caledonia crows have been seen to make two different sorts of hooks to snare food, even with no previous exposure to someone bending a wire into a hook. Avians have shown again and again a propensity for calculating spacial relationships, understanding symbols and even, in the case of parrots, constructing and communicating in a verbal language that humans can understand.
Chimpanzees and other non-human primates, on the other hand, have never shown any indication of spontanious modification of an item to create a specialized tool.
