Transfer duck stamp between licenses?

Question:

I bought a duck stamp, attached it to my 2013 Sportsman's Package license, and signed the face of it (as per the instructions that come with the stamp). Now that I have my 2014 license, I am wondering if I have to buy a new duck stamp (even though the old one is still valid). Can I just keep the old license (with current duck stamp attached) in my possession?

Answer:

Federal duck stamps are valid July 1 of one year through June 30 of the next.  You can carry it with you during the spring/winter waterfowl seasons.  The stamp isn't associated with a particular license number, but with the hunter who has signed it.  You can carry it with you for the time it is valid as long as it is signed.
