Not sure and I think I saw different species. But Jackdaws, Magpies, Ravens are smarter than your average Nigger-Bird. ;) Rabenvögel is the German word for the ?subspecies? (Not a biology whisperer). I've seen videos of very impressive shit these dudes pull off. Like dropping nuts on the road to have cars crush them, then harvesting the seed. Also facial recognition of people that were mean to them and spreading that knowledge within the flock.
