We’ve shown you some amazing videos of smart crows. It turns out ravens are not only bigger, they’re smarter too.
L. Kilham in The American Crow and Common Raven writes, “Ravens are, to enthusiasts like myself, at the top of the avian pyramid in mental attributes.”
Judge for yourself as you see what brainy critters they are in these 3 videos.
Ornithologist Bernd Heinrich of the University of Vermont devised an experiment to show that ravens have the ability to make logical connections, much like human beings. He dangled food on a long string, something a raven would never encounter in the wild. See how the raven figures out how to get the food.
The next two videos, on pages 2 and 3, show more examples of raven cleverness, as they find creative ways to get food out of a tube. The tube on page 2 is pretty simple; the one on page 3 provides much more of a show.

Get the Food in the Tube
A couple of ravens have the opportunity to get a small bucket of food out of a tube by pulling it up with a piece of wire. One fails and gives the opportunity to the other. This one figures out how to bend the wire and hook it on the handle of the bucket. Pretty clever, we’d say.
Think this was impressive? See what the ravens do to get their treat on page 3.

Get the Food in Fancy Tube
In this BBC video we meet two more ravens with a much fancier tube. It is U-shaped; if a raven drops rocks in one side he will raise the water level on the other side so that the bucket of food will be in reach. Watch the ravens’ performance then wait for the dénouement.
