Ive been pondering lately that as we've learned more about corvid intelligence and the ability for birds to discern a wide variety of calls with a great degree of accuracy, the old insult "bird-brain" has aged rather poorly. They seem to be much smarter than we gave them credit for all the way to the unfortunately named dodo bird and its old inaccurate depiction that took hold in public conscience.

Now apparently they have an similar thing to our proprioception(tho hard to tell if as accurate as ours) if I'm understanding the abstract correctly.
