There is little information on Long-tailed Duck population trends; numbers are difficult to census because of the species' offshore wintering areas. Long-tailed Duck rates a 12 out of 20 on the Continental Concern Score, and is on the 2014 State of the Birds Report as a Common Bird in Steep Decline. These ducks are not widely hunted. Entanglement in fishing nets killed tens of thousands of Long-tailed Ducks in the 1950s, especially in the Great Lakes; recent statistics and trends on by-catch of Long-tailed Duck have not been compiled.Back to top
