Animal Behavior: Tool Use By Parrot

One of the signs of higher intelligence, according to the humans who came up with the criteria, is tool use. Of course, primates create tools, because primates have hands, so this is a very selective sign of higher intelligence. Real life problem solving is a better sign of intellect, in my opinion, and that is also on display in this video. But, I am always happy to see obviously intelligent species get some due in the scientific community.
