something i was wondering the other day!

So I was sitting outside and watching the birds eat bread, and there was this bird sitting on our fence..... he pooped, looked around, and flew off. Do birds get nurvous pooping in front of other birds? like women who meet a new guy and dont want to scare them off, they hold their poop in for so long it hurts? until they break the new guy in and he finds out that women do poop! i know that birds brains are smaller then a peanut but im just a curious mind!
