Their feet are placed far back on their bodies which makes them efficient swimmers but very awkward on land. These large webbed feet paddle them through the water. In the winter, loons change to a gray-brown color before they move south. The red eyes help loons see better underwater. Loons spend the summer in Alaska, Canada, and northern Border States.
Loons fly south to the coast for the winter.
This phenomenon is known as migration. Birds migrate during different times of the year to find food. The winters in northern climates are too cold for loons. They depend on fish to eat and since the lakes freeze over during the winter they must move south to find food. Loons mostly eat fish such as yellow perch, trout, and minnows.
