Hitting Bottom
By the look of his mud-tipped bill, I'd say this ruddy duck hit bottom. I guess that's to be expected. From what I read they dive to the bottom of a pond and filter mud through some plates in their bill to get at aquatic invertebrates, plant matter and the like. Not sure I fully grasp the physical mechanism for this filtering process. Back to this guy. He'll need to clean that mud off - that ridiculously blue bill is there to attract the ladies during the breeding season (which is now)
