there are clear links for at least 2 evolutionary paths: bird brain architecture is very different from that of mammals and some are among the smartest species on the planet. they have sophisticated language and social relationships, they can deceive (meaning they can put themselves inside another's mind and act accordingly), they solve problems and they invent and engineer tools for specific purposes and use them to that effect. give them time and these bitches might even become our new overlords (if we're still around, that is).
