Birds are really freaking stupid. It's no wonder they've been pigeonholed as bird-brains!
It has happened to me on more than one occasion that I could have killed a bird with two stones . . . figuratevily of course. Meaning that I've been driving and a bird will be in front of me . . . walking on the ground and instead of flying to get away from me it will run like crazy on it's twiggy little wings.
Uh . . . hello?? Wings? Fly? Get away.
