Migratory Waterfowl Stamps (Duck Stamps)
by Mark Kness

Federal Migratory Bird Hunting and Conservation Stamps, commonly known as "Ducks Stamps," are pictorial stamps produced by the U.S. Postal Service for the U.S. Fish & Wildlife Service. They are not valid for postage. Originally created in 1934 as the federal licenses required for hunting migratory waterfowl, Federal Duck Stamps have a much larger purpose today.

Today, many states also issue their own versions of duck stamps. In some states, the stamps are purely a collector`s item, but in others, the stamps have a similar role in hunting and conservation as federal duck stamps.
