Yeah. Though they're smart enough to operate guided missles apparently.. but... still pretty stupid animals... are they smarter than humans? bonobos? gorillas? porpoises? Same goes for the jumping spider... which I think is so low in the answers because you take something very generic for, like, "dog".. but jumping spider is a bit more specific. Lastly, maybe you could accept raven for crow? They're the same species.. but ravens are larger and smarter than crows.
Yeah, i got this info of multiple websites and compared them, pigeon appeared more than once which surprised me as well but i went along with it anyway. There is no definite order and every website disagreed with each other. So making this quiz proved quite difficult and controversial. However, I will change anything you would like me to change.
well this obviously isn't an absolute ranking. I mean, nobody would say that a pigeon is smarter than a gorilla or bonobo (or human, we're animals, too). Maybe you could just do it by category like I did with my Fastest Animals quiz. So.. smartest bird found in North America (Raven), smartest non-human primate in SE Asia (orangutan), etc... just to avoid confusion. but that would require a little more research. Or just forget about it and leave it as is. :)
