I have always loved crows and ravens. They are amazingly intelligent and resourcebul birds. Years back, I read the Mind of the Raven by Bernd Heinrich, which provides a fascinating look at how Ravens think and behave. So, I was quite interested in the following video which presents a crow with an eight-step puzzle to solve using sticks and stones as tools.
The crow in this video had been previously exposed with the individual steps of the puzzle but had not been presented with them in combination before. Watch as the crow studies the problem and completes the puzzle in relatively short order. It is amazing! You can also read more about how crows utilize tools and solve problems on BBC News.
