Agreed. But before they even got smart enough to sneak up, they had to somehow know that the tears were even there to be gotten.
How did they know? Smell?
I also wonder how this is for the birds. A good thing? Does it benefit them somehow? Or does it depelete them of needed tears that keep their eyes moistenened?
