Bald eagles are migrating back to the state
Bald eagles are migrating back to Minnesota and may be seen in large numbers across parts of the state over the next few weeks, according to the Department of Natural Resources.
“Ice is breaking up along the rivers, so it’s definitely time for folks to keep their eyes out,” said Lisa Gelvin-Innvaer, DNR regional nongame wildlife specialist. “It all depends on the weather. It’s typical to see eagles coming through our area in mid-to-late March, as waters begin to open up and snow melts.”
Only two states, Florida and Alaska, have greater nesting populations of bald eagles than Minnesota. In 2005, researchers estimated there were more than 1,300 active nests in Minnesota.
Fall migration typically occurs as lakes and rivers freeze over, since most eagles prefer a diet of fish. Bald eagle wintering grounds ideally contain open water, ample food, limited human disturbance and protective roosting sites.
Not all bald eagles migrate southward in the fall, Gelvin-Innvaer said. In southern Minnesota, it’s common for some eagle pairs to stay the winter, especially during milder winters.
