To require the United States Fish and Wildlife Service develop a plan to halt the illegal harvesting of migratory waterfowl.

Directs the U.S. Fish and Wildlife Service (the Service) to: (1) research and develop methods to accurately determine the number of migratory waterfowl that are harvested illegally each year in the United States; (2) develop a plan to increase its law enforcement presence and better coordinate its efforts with those of appropriate State agencies to halt such illegal harvesting; and (3) recommend whether specified wildlife conservation funds should be withheld from States that are not complying with the Service's regulations on illegal harvesting.

Requires the Director of the Service to report on such findings to specified congressional committees within 90 days of enactment of this Act.
