Birds are fukking dikks by nature so the bigger, the worse.
One of those ostrich fukkers almost killed Johnny Cash.
"I missed. He wasn’t there. He was in the air, and a split second later he was on his way down again, with that big toe of his, larger than my size-thirteen shoe, extended toward my stomach. He made contact—I’m sure there was never any question he wouldn’t—and frankly, I got off lightly. All he did was break my two lower ribs and rip my stomach open down to my belt, If the belt hadn’t been good and strong, with a solid belt buckle, he’d have spilled my guts exactly the way he meant to. As it was, he knocked me over onto my back and I broke three more ribs on a rock—but I had sense enough to keep swinging the stick, so he didn’t get to finish me. I scored a good hit on one of his legs, and he ran off."
Johnny Cash was 6'2" was a big dude too.
