Lake Wausau is a great place for viewing waterfowl migration, especially during the spring when the variety of loons, grebes, ducks and more are most abundant. April to early May is prime time for viewing this variety of birds as they migrate through our area to their breeding grounds farther away. Ducks, such as Ring-necked Duck, Lesser Scaup and Bufflehead, can be very abundant at certain times. From late March to early April is the prime time to watch for migrating Tundra Swans as they pass through to their arctic breeding grounds. Common Loons and Horned Grebes often stage here in good numbers before moving onward as well. Fall migration on Lake Wausau can also be good at certain times, and the late fall season is the best time of year to look for unusual to rare waterfowl that have visited the lake during migration. Some unusual to rare duck sightings have included all three scoter species (Surf, Black and White-winged), Long-tailed Duck, and Barrow’s Goldeneys Marathon County lies within the Mississippi Flyway. The flyway represents the migration route of over 325 bird species making their yearly journey from their wintering grounds to their breeding grounds. The breeding grounds stretch north into Canada, with many species using our area by following the Mississippi River to the Wisconsin River. Waterfowl such as ducks, loons, grebes, and geese use these waterways to rest and feed during their migration. They can follow the river north to the lakes of northern Wisconsin, which they use as resting stopovers. Besides waterfowl, shorebirds also use this flyway with some making the extraordinary trip from the Antarctic to the Arctic. The Mississippi Flyway, in the United States, begins at the delta of the Mississippi River and ends in northern Canada. This flyway doesn’t cross any mountains, so that helps the birds conserve precious energy. It is estimated that 40% of all the waterfowl and shorebirds found in North America use the Mississippi Flyway. The Mississippi and Wisconsin Rivers also lead waterfowl and shorebirds to the Great Lakes, which also provide these migrants areas to rest safely and to feed on their journey. The Wausau Bird Club has included in the QR Code a checklist of all the waterfowl and shorebirds that can been seen along the Wisconsin River and in Lake Wausau. So, have your binoculars ready for the parade of birds!
