Wildlife Update: May 12, 2026

Featured Image By: Jeremy Kuecker

Weather has been cooler the past few days, but the extended forecast looks like warmer weather is on the way! With some days having a south wind over the past week, migration is in full swing in the Grantsburg area, with new species being spotted daily. Our bird list for the past week reached 167 species!

Some waterfowl species are still hanging around the area, but many will be starting to nest at this time. Songbirds are moving through the area at this time, with numerous warbler species sighted over the weekend.

Grettum Flowage is currently drawn down to mudflats, making it perfect for shorebird viewing. Species like Wilson’s Phalarope, Dunlin, Least Sandpiper, Long-billed Dowitcher, and more sighted at this location.

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 and Wild Turkeys.

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.
