...they're more feral than the Pigeons, meaning the Pigoens are more evolved.
I still can't get behind your idea of evolution: differently evolved seems more appropriate. I'm assuming you mean feral to denote a higher degree of aggression and from the standpoint of getting food in the wild, that might be more evolved. From the standpoint of getting more food from you, it might be less evolved, but only if it prevents them from attaining their goal. Similarly, Aikido evolution of pedagogy depends upon what you're trying to acheive.
