Wildlife Update: March 25, 2026

Weather is slowly becoming more spring-like in the Grantsburg area; we even had a 75-degree day within the past week! Most days over the last week had been in the high 40’s and 50’s, melting off most of the remaining snow on Crex Meadows, Fish Lake, and Amsterdam Sloughs. We are seeing patches of open water around our properties at this time and will expect more open water to pop up by the day.

With water beginning to open around the county, there are different migrating birds showing up every week, including a variety of waterfowl, the first shorebirds, and more.

Springtime also means mating season for birds, and there have been several species participating in mating displays observed this week, including Sharp-tailed Grouse, Sandhill Cranes, Trumpeter Swans, and Wild Turkeys.

Highlights this past week include American Wigeon, Blue-winged Teal, Brown Creeper, Bufflehead, Common Goldeneye, Greater Scaup, Green-winged Teal, Eastern Bluebird, Eastern Meadowlark, Killdeer, Northern Pintail, Pied-billed Grebe, Red-winged Blackbird, Sandhill Crane, Tundra Swan, and Wood Duck.

Most roads in Crex Meadows, Fish Lake and Amsterdam Sloughs have been holding up quite well for the most part, but some have been extremely muddy. It is a good idea to check in with Visitor Center staff before making a trip to the area so we can give you the most current information.

Top viewing locations this week: Dike 6 (open water, and lots of ducks, geese and swans), Refuge Extension Flowage (some open water, dozens of Bald Eagles), Phantom Lake (the best place to view Trumpeter Swans).
