IIRC, a biology teacher that was raised on a farm said that a crow could
count. But only to three, IIRC. So, if two guys went into a blind and one
left, the crows would know that someone was still in there. He said that
they would have to take at least one more guy than the crows could count to,
then some would leave, and the crows would come around again, thinking they
all had left.

Don't know if this is true or not.

All birds in the corvid family (that includes, ravens, crows and jays, among
others) are very smart. ravens and blue jays are tool users! ravens can solve
puzzles, and it's been shown that they can VISUALIZE how to solve a puzzle even
if the puzzle was removed before they could initially solve it!
