Weeeellllll, technically there are. The same laws that prohibit the keeping of a live bird also prohibit the possession of any "part, nest, or eggs of any such bird", living or dead. This includes feathers and body parts (or entire bodies). But I won't tell anyone if you won't. And I most certainly don't have any whole specimens in my freezer pending donation to the local museum collection... nooooo...
Edit: Here's a summary of the law, for those interested.
