Birding Information

11/17/2020 This is week nine of waterbird surveys at the refuge for the fall migration. Last weekend a strong front came through Wisconsin with 40+ mph winds and rain showers. This brought down more cranes and mallards. More than 80% of the marsh was frozen (1/2” ice) on this week’s survey. Most birds were congregated in the middle of the marsh in open water. Anticipated warmer weather through the beginning of next week will bring back the open water. Canada goose numbers decreased- about 20,000 were counted on the refuge this week. Fall harvest is nearly complete. Many geese and cranes were observed feeding in corn stubble surrounding the refuge. Dabbling ducks numbers increased this week –almost 68,000. A big influx of mallards made up 90% of that total -~61,000. The only other species seen in the thousands was green-wing teal. Northern shovelers, Northern pintails, American black ducks, and gadwall were seen in the hundreds. Diving duck numbers total about 900. Three species were seen in the hundreds – buffleheads, ruddy ducks, and ring-neck ducks. A couple small groups of hooded mergansers were seen. The rest of the divers were absent, likely due to being frozen over. Other sightings to note: •Sandhill crane spectacle. Come out and see/listen to the thousands of sandhill cranes as they stage at the refuge for migration. Hundreds can be seen feeding in farm fields – especially along the east side of the marsh. •Swans – both tundra and trumpeter were seen in the pockets of open water. •Watch for American black ducks mixed in with the large mallard flocks. •Snow geese are mixed in the Canada goose flocks. •Notable decrease in numbers – canvasback, redhead, American coot, American wigeon, and scaup. Waterfowl viewing is getting tougher as winter approaches. This week the last impoundment around the auto tour had the best viewing close to the road.
