It's weirder and more depraved than that: their penis explodes out of them in what is called explosive eversion and they have to regrow them every year. This is so they can find their way down the maze of duck vaginas
Where do you get the need to regrow them part? I didn't see anything about that in the linked article. And the "explosive" part just means they erect them really fast.
It's not talked about in the paper I linked. Aside from that, it appears that I've remembered it incorrectly or it was misreported when I learned about it. It appears that their penis simply shrinks and is almost vestigial until the next breeding season, when it grows again and gets bigger depending on how many males are in the area
What the duck?
Nature is so wierd. A strange force where persistence and randomness intersect in all sorts of ways.
