Representative John Kline, Minnesota, has introduced a bill that would amend the Migratory Bird Treaty Act to allow states to kill large populations of double-crested cormorant- "The Cormorant Management and Natural Resources Act" (H.R. 3074). The bill is based on invalid science and the misguided belief that they are "eating all the fish."
There is ample research that shows double-crested cormorants rarely have much effect on any fish stocks at all. In fact, double-crested cormorants actually benefit fish stocks by weeding out the unfit, and preying on predators or alien species. Double-crested cormorants also often are instrumental in helping to make soil suitable for vegetation.

This amendment would allow states to cull large populations of double-crested cormorants. The Migratory Bird Treaty Act is a federal issue and "management" should remain a federal responsibility.
