Well.. it all startedout as a joke at work. I read an article about a study of small birds.. How they nest. Prefernces, food sources and so on. It was compared to human behavior and choice of partner.

So i was like.. yeah must be boring beeing a bird. Yuo got the nest, partner.. perfect place.
Then you kinda figures out that you have no dick! Like.. how do male birds copulate?

Thinking of it i guess they must be a bit like a stealth bomber.. Folding it out in need of a missile.

Then comes the next question.. how do they engage? Mid air? Or do they jump up on each other?? Guess i could find it out if i googled about it.. but im to lazy, and after all im looking for interesting answers.
