Bird brains

Is this dumb or smart? I think it began smart but then evolved (BLACK INK!!!) into dumb. =) Also, according to my functional neuroanatomy professor, pinching the back of your neck is supposed to result in pupil dilation. (You know... that black hole in your eye?) I have not verified the truth of this myself (yet) but feel free to practice this ciliospinal reflex in the privacy of your own bathroom.
