Wildlife Update: August 3, 2026

Featured Image by Nancy Jahnel

Weather has been mostly hot in the Grantsburg area, but there have been a few cooler days mixed in. The 10-day forecast looks like many days will be in the high 80’s and some may dip into the high 70’s.

The highlights for viewing this time of the year are summer resident birds, wildflowers in bloom, and our many butterfly species! We are seeing some of the earliest signs of migration, including some shorebirds coming to the area. There are mudflats on North Fork Flowage that are great for viewing shorebirds and other wading birds, such as egrets and herons. Baby animals are going fast, with many of the birds being close to the size of their parents at this point and becoming much more independent.

Grettum Flowage on Fish Lake Wildlife Area is drawn down still, and because of this there are a number of birds that have moved over to Dueholm Flowage, including American White Pelican, Double-crested Cormorant, many Trumpeter Swans, a number of different ducks, and more.

Highlights this week include: Great Egret, Least Bittern, Least Sandpiper, Pectoral Sandpiper, Semipalmated Plover, Semipalmated Sandpiper, Solitary Sandpiper, Spotted Sandpiper, and Wilson’s Phalarope.
