Birding Information

10/29/2020 This is week six of waterbird surveys at the refuge for the fall migration. Southern Wisconsin saw the first measurable snow last weekend. This front moved many birds out of the area. Large groups of tundra swans arrived with the front – staying only a couple days. Big increases were seen in mallards (18,000+) and green-wing teal (17,000+). Canada goose numbers remained the same- about 20,000 on the refuge. Corn harvest continues throughout the area. Geese, ducks, and cranes are flying out of the refuge several times a day to feed in the harvested fields. Dabbling ducks were most numerous again this week. Impressive numbers of mallards and green-wing teal were seen this week on the survey. Top species seen in the thousands were mallards, American wigeon, gadwall, and Northern shovelers. Others seen in the hundreds included Northern pintails and American black ducks. Diving duck numbers stayed about the same. Top species seen in the hundreds included ruddy ducks and buffleheads. Other species spotted in small flocks included redheads, ring-neck ducks, canvasbacks, hooded mergansers and scaup. Look for these divers along Hwy 49 –both sides of the highway. Other sightings to note: •Large rafts of American coot can still be seen – especially along Hwy 49. •Sandhill crane numbers are increasing – watch for flocks in the hundreds in farm fields – especially along the east side of the marsh. •Buffleheads and hooded mergansers arrived. •Tundra swans arrived. Check out the north side of Ledge Road (the west section of road that enters the marsh) – 13 species of ducks were seen along there including hundreds of gadwall, Northern Shoveler, American Wigeon and green-wing teal. The north side of Hwy 49 had 10 different species of ducks. Check this area for diving ducks. Redhead, canvasback, ruddy ducks, buffleheads, scaup, and hooded mergansers were seen. Bring binoculars and a spotting scope.
