Migrating Bald Eagles

Keep an eye on the sky in the upcoming weeks in search of migrating bald eagles.  Along the shore of Lake Superior is a great place to see bald eagles because there is open water. Once the eagles make their way back the breeding begins. Bald eagles usually mate for life and for a detailed description of exactly how bald eagles breed you can check out this website. There’s a large nest along Highway 61 not too far from town we like to keep our eyes on and another one down at the Trail’s End Campground. Here’s more about the Bald Eagle Migration from the Minnesota DNR.

Bald eagles on spring migration back to Minnesota

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 Minnesota 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 and that number likely has increased since.

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.

Bald eagles that stay local may begin courting and nesting as early as December or January. Other bald eagles return to their breeding territories as soon as a food source is available.

“Eagle migration hotspots are a bit of a moving target, so it’s hard to say where the eagles are right now,” Gelvin-Innvaer said. “In Minnesota, the biggest migrations tend to be along the Minnesota River corridor, the north shore of Lake Superior, and around Lake Pepin in southeastern Minnesota.”

Adult bald eagles are easily identified by a white head and tail contrasting with a dark brown body. They attain full adult plumage in their fourth or fifth year. In flight, bald eagles are sometimes confused with turkey vultures. However, bald eagles tend to soar on flat, board-like wings, while turkey vultures fly with their wings in a v-shape.

Bald eagles are an example of how they and many other wildlife species benefit directly from donations made to the nongame wildlife checkoff on Minnesota tax forms or online at www.dnr.state.mn.us/nongame/donate/index.html. This funds research, surveys and education for more than 700 nongame wildlife species. Each dollar donated is matched by funds from the Reinvest In Minnesota account.

The DNR’s Nongame Wildlife Program is now streaming live video of a nesting pair of bald eagles on its website at www.webcams.dnr.state.mn.us/eagle.
