Mixed Ducks Taking Off From a Wetland

Horicon National Wildlife Refuge Fall 2021 Migration Report 12/8/2021 This is week twelve of waterbird surveys at the refuge for the fall migration. This will be the last fall migration survey update for 2021. The marsh was completely frozen on this week’s survey with ice thickness between 3-5 inches. The marsh and surrounding area had around 1” of snow. More snow is expected in the next several days followed by unseasonal warmth next week. Canada geese: Around 2,000 geese were counted on the refuge this week. Dabbling ducks: No dabbling ducks were counted on the survey. Flocks of mallards had been seen in the area prior to freeze-up. Diving ducks: No diving ducks were counted on the survey. Other sightings to note: · More than 3,500 sandhill cranes are in the area right now. You can watch their daily flights in and out of the marsh. Flocks of 200+ can be seen feeding in fields close to the marsh during the day. Sunrise and one hour before sunset are the best times to see large flocks’ transition between the roosting and feeding grounds – especially along the east side of the marsh. They will likely be here in numbers until we have snow preventing easy feeding in upland fields. · Snowy owls and rough-legged hawks have been seen around the marsh. Most of the remaining birds can be viewed from W Point Road – on the viewing platform at the Bud Cook Hiking Trail. The birds have been roosting and standing on ice west of Point Road. Also driving Ledge Road (the west section of road that enters the marsh) may afford a view of birds loafing on the ice.
