I could not resist posting a quick set of links on what I know is a remarkably frequent occurrence, but one many people simply cannot believe takes place. Dr. Darren Naish of Tetrapod Zoology and SV-POW just blogged a new post on the "unique" mating habits of the mallard duck (Anas platyrhynchos). A previous TetZoo post on the subject can be found here.
I have yet to witness mallards engaged in this type of behavior, but man, would that be a treat. For me that is. The female mallard on the other hand... not so great for her. Sorry lady ducks.
Ed Yong over at Not Exactly Rocket Science has a pretty substantial post up from 2009 as well. This one features videos of the anatomy in action. Mind bombs are going off in my head.

Welcome to Superoceras, a blog about science and natural history, slightly biased towards paleontology and zoology, but inclusive of all sciences. Started in October of 2009, my goal is to communicate scientific knowledge (and the occasional piece of nonsense) in an informative and entertaining manner. Feel free to contact me with questions, comments, concerns, or criticism at superoceras(at)gmail(dot)com, and follow me on Twitter @Superoceras for all that and more in 140 characters or less!
