Long-tailed Duck

Clangula hyemalis

The breeding range of the Long-tailed Duck is extensive and occurs mostly outside of areas covered by most established waterfowl surveys, so there is very little information available to accurately and reliably quantify population size and trends for this species. The North American population of Long-tailed Duck has been crudely estimated at one million birds.
