Black Dog Lake is one of these spots. Black Dog Lake is a small lake that is adjacent to the Minnesota River and part of the Minnesota Valley NWR. An Excel Energy plant located here pumps warm water out keeping part of the river and lake open during the winter.
Open water is usually a big key to finding suitable winter wildlife habitat. Most waterfowl have layers of down feathers that help insulate their bodies while they swim in the icy waters, like this common merganser in the photo above.
Many different types of ducks are found in the open water, such as mallards, common goldeneye, plus common and hooded mergansers. Larger birds like Canada geese and trumpeter swans can also be found dabbling in the frigid water looking for plants and roots to eat.
In the large trees lining the river you will often see bald eagles perched using their acute vision to see fish in the icy waters. During the winter the mortality rate of fish goes up. This helps the eagles survive at this difficult time of the year since it is much easier to catch a dead fish floating in the river.

What a lovely introduction to Black Dog Preserve. Winter time in Maine is much the same. Most birding is done along the frozen river banks in the cold wind, or in the farmers fields looking for snow buntings and the like. Brrrrrr. Ducks are BEAUTIFUL! I never reallized it until I started birding. Ducks just look like ducks to the naked eye. Nice photos. ~karen
