Wildlife Update: April 22, 2026

Spring weather has been much more consistent in the Grantsburg area this past week! Most days were in the 50’s and 60’s, with a couple of days even reaching the 80-degree mark! We have had some precipitation fall over the past few days, with more rain (and potentially storms) in the forecast for the coming days.

Many waterfowl species are still hanging around the area, with the best viewing opportunities being down at Grettum Flowage on Fish Lake Wildlife Area. Grettum also has low enough water in some areas where mud is exposed; these areas are perfect for shorebird viewing. Species like Greater and Lesser Yellowlegs and Pectoral Sandpiper have been sighted there in the past few days.

Springtime also means mating season for birds, and there have been several species participating in mating displays observed this week. The most visible displays are put on by Sharp-tailed Grouse, Sandhill Cranes, Trumpeter Swans, and Wild Turkeys.

Highlights this past week include American Bittern, American White Pelican, Eastern Towhee, Red-necked Grebe, Ruddy Duck, and Short-eared Owl.

Most roads in Crex Meadows, Fish Lake and Amsterdam Sloughs have been holding up quite well but can be wet and muddy after significant rainfall. It is a good idea to check in with Visitor Center staff before making a trip to the area to learn the most current information.

In the springtime, the Wisconsin DNR conducts several prescribed burns on State Wildlife Areas. While you are visiting Crex Meadows, Fish Lake, and Amsterdam Sloughs, you may notice smoke in the air. These fires are likely controlled by DNR fire staff monitoring them the entire time until they are confirmed to be out. However, springtime is also wildfire season in our area, so it’s important to be aware of your surroundings.
