"Ashkui" Vernal Ice-cover Phenomena and Their Ecological Role in Southern Labrador

Shauna M. Baillie, Corinne D. Wilkerson, Tina L. Newbury

Abstract


This is the first documented incident of River Otter (Lutra canadensis) feeding on Common Goldeneye (Bucephala clangula) in a little studied region, southern Labrador. Our observations were made during spring staging when waterfowl aggregate at open water sites in frozen lakes and rivers, locally known as ashkui. We suggest that otters and raptors opportunistically forage on staging waterfowl at ashkui.
