How birds have sex...

[Mister Obvious]

I found myself still confused, so I decided to take awhile and look at some photos.

What has really stumped me about this whole thing is effectiveness. What are the odds of success for just rubbing tail feathers? It seems like such a stretch.

Luckily these pictures helped me understand, as you can see, those birds are doing it right:

I have no idea what's going on right here, but it looks like it could work eventually:

Super proud of these birds, seems very effective:

But then I looked up penguin sex.

Now there aren't very many pictures of penguin sex, but from what I can tell, it looks even more impossible and ineffective than regular bird sex:

If the penguin on top were to angle himself effectively, he'd fall over backward.

I am not attempting to disrespect or second guess nature... I'm just saying, I think it's a miracle birds ever reproduce.
