Wildlife Update: September 22, 2025

Weather has been variable in the Grantsburg area over the past week, with temperatures varying from some days in the high 80’s to some days with highs in the high 60’s. We have also had rain and storms on and off the past week. The 10-day forecast looks to be relatively consistent, with many days looking like they will be in the low to mid 70’s with no significant rain or storms.  

Now is the time of the year where we are within our fall migration. Keep a lookout for a variety of ducks, some remaining songbirds and shorebirds, geese, and watch for some of our local birds to begin flocking up (ducks, Sandhill cranes, etc.). We will expect to see more of this behavior as we move through the rest of September and into October.

Sandhill Crane viewing season is coming up quickly! We are seeing groups of cranes hanging around together in some of our flowages and in local fields that are nearby, and numbers are beginning to build slightly. This migration is still in its earliest stages, however, and we won’t be seeing our peak numbers of cranes until late in October.  

Grettum Flowage and Phantom Lake have both been quite active recently, with Grettum still holding many American White Pelicans, Trumpeter Swans, and Double-crested Cormorants. Another highlight this week was our first sighting of Northern Shovelers in the area, spotted on Phantom Lake over the weekend.
