Maybe that is why crows can count and parrots can do monologues. Link to comment Share on other sites More sharing options...

turkeyfoot Posted June 14, 2016 Share Posted June 14, 2016 Great Scott. Usually I ignore crows. They are to me, simply, a bird of another color. Buzzards are a protected species here and they are a plague on a neighbors house. I just cant help but think crow epistemology was a label not befitting of bird brain derision. Their brain to body size has an equivalence to chimps and humans brains/body mass. Other than these few things I couldnt care less about crows.

So do humans. Humans sometimes use magnetic compasses to navigate and they also use GPS who clocks tick using oscillations of electromagnetic fields of atoms. That is all quantum stuff. Eyes also work on quantum principles. The effect of photons on rhodopsin (the chemical in the rods and cones) can only be understood quantum mechanically.
