Duck stamps - officially Federal Migratory Bird Stamp - are no longer available directly from Fish and Game. They are available for $15 at U.S. post offices, and they can be ordered by buying a receipt good for 45 days for $17.75 at Fish and Game offices, license vendors or on the Internet at: https://id.outdoorcentral.us/. Internet and telephone orders will add a convenience fee. The stamp will be mailed directly to the hunter. Anyone 16 or older who hunts migratory waterfowl must have a valid duck stamp in their possession and signed in ink by the holder. It is in effect from July 1, 2011, through June 30, 2012.
