unexplored concept in furry: bird intelligence is fundamentally different from mammal intelligence. a raven does not think like a dog or a human

different types of avian intelligence too. the corvids hijacked the songbird brain to gain theirs, but chickens are basically just state machines, if you anger them and then throw corn at them they'll just start eating it instead
