Which stamp must duck hunters obtain to hunt legally?

To legally hunt ducks in the United States, including New Hampshire, hunters are required to obtain a Federal Duck Stamp. This stamp is not only a permit that allows hunters to engage in waterfowl hunting, but it also contributes to the conservation of wetlands and habitats that are vital for waterfowl populations. The funds generated from the sale of these stamps are primarily used for the purchase and preservation of crucial waterfowl habitats.

While state hunting stamps or licenses may be necessary for general hunting activities within each state, the Federal Duck Stamp is specifically mandated for anyone pursuing migratory waterfowl like ducks. This requirement reflects the federal government's commitment to waterfowl conservation and the management of migratory species. Other options such as the Waterfowl Observation Stamp and the Species Protection Stamp do not have the same legal implications or requirements for duck hunters. These stamps serve different functions and are not related to the legal requirements for hunting.
