I'm up in Stockton this weekend, and Rhonelle's apartment complex features a lot of little "canals" populated by many ducks (it is a feature at many of the large complexes up here). Periodically the ducks will make a walking migration from one part of the complex to another (for reasons I don't know), and as I was standing outside this morning I was quickly surrounded by about thirty ducks. They were quite passive and seemed to think I had food. So, I was checking out the ducks and was struck with the question: why are ducks' feet orange?

If you ever wondered the same thing, some answers can be found at this web site.
