This has probably been discussed on here but a search of 'duck' didn't return any penis-related results.

Regardless, these are the first videos I've seen of these things in action. Pretty gross and weird that someone would want to research this. I'm pretty sure he/she gets duck spooge on their hand in the first video.

More on animal penises and sexual conflict:

Quote :

"This is a bull elephant firmly establishing why it is he, and not the lion, who is king of beasts. The elephant’s penis is not only massive but prehensile. As we watched in baffled amusement (and the faintest tinge of inadequacy), he used his penis to prop himself up (as in the photo), swat flies from his side and scratch himself on his stomach. David Attenborough never showed us that…"
