Crows are smarter than great apes and about on par with a 5-year-old child. We know they (and similar birds) can already complete complicated tasks, like putting a stick through a tube to finagle out food. But in this BBC video, the crow, after thinking it over briefly, easily completes a multi-step puzzle.

I was not sure about the solution to this puzzle until very close to the end of the video. I choose to believe this says more about the crow than about me. Bravo, crow.
