White-winged Scoter Melanitta deglandi
7 December 2013
White-winged Scoter is common to abundant on Lake Ontario during the winter, finding a ready and plentiful source of food in the Zebra Mussels Dreissena polymorpha that now plague our inland waters. The white secondaries from which the bird derives its name are hidden until it takes flight. These males are easily distinguished by the white patch around their eye, and their brightly coloured bill.
