Crows are very intelligent. I saw a documentary some years ago about how smart they are. Searched for it but couldn't find it back.

I watched that I think,it was on History or PBS..Can't remember exactly,but the Crows solved some very complex puzzles


Perhaps this is it.

They did a few experiments in the past testing monkeys, pigs, and ravens in Scandinavia. As I remember it took around three years to teach a monkey how to use a sort of tablet computer. The test was to locate patterns in symbols and it turned out the monkey has a faster "CPU" than humans. That is, no humans below 16 years old was able to solve these puzzles and those able to used way more time to do so.

Later the same thing was done to a pig and the pig only needed a few months to learn solved even more difficult problems than the monkey.

After this two studies was done of ravens. One in Norway and one in Sweden. The first one was a practical/technical test done in Norway. They filmed this using cameras inside and outside of a house where the actual test took place on a table outside. They did a lot of these tests, like putting a piece of fat in a glass-tube and lay a steel wire beside the tube. The raven then pick up the wire, make a hook at the end and fish up the fat from the tube.

After each test the raven took the piece of fat and flew into the yard and dig a whole in the ground to hide it for later.

The Swedes follow a group of ravens for a long time following their interaction with other animals. In one sequence the ravens was following a group of wild boars in the forest. There was apparently a special place there with some goodies in the ground the raven craved. When the pig dig them out one of the raven attack the pig while the rest of them was feeding.

A few decades later the material was digitalized and they then reviewed the footage from the first test. One of the cameras outside capture the raven when for a split second it was out of view from inside of the house. It turns out the raven was chipping the fat into the long grass at this point and then just "pretended" to hide the fat in the yard. This means the raven was aware that it was watched and reveal a very sophisticated form of empathy never observed before.

As a result the Swedes reviewed the whole forest clip and it turns out the raven was actually guiding the pigs into this particular place. They attacked them if they stopped or went the wrong way.

The conclusion, given the raven outsmarted the scientist and the pig  :P

A few years ago, a group of reputed scientists tested with chimpanzees, administering certain sera. The results were amazing.
