migratory birds

Imagine walking down a picturesque beach along Lake Michigan, and stumbling upon the carcasses of dead birds. That’s a very real and unpleasant problem along Lakes Michigan, Huron, Ontario and Erie. (It’s not as big of an issue in Lake Superior because of the lake’s colder water temperatures.)

Loons and other deep-diving birds are suffering from a disease called avian botulism. It’s form of food poisoning that kills wild birds in the Great Lakes ecosystem.

The Nature Conservancy has purchased an uninhabited island in northern Lake Michigan that provides a crucial stopover spot for migratory birds.

St. Martin Island is part of a chain that runs between Wisconsin's Door Peninsula and Michigan's Garden Peninsula.

Millions of sparrows, warblers and other birds stop on the chain to take a break and feed before continuing their migration. According to a release issued by the group today:

With the chill in the air now, you might guess that most hummingbirds would have ditched Michigan for a more tropical place.

The Ruby-throated hummingbird is the bird you’re most likely to see in Michigan, and it has flown south, for the most part.

But Allen Chartier still wants you to keep an eye out on your backyard feeders.

He studies hummingbirds and he’s the project director for Great Lakes Hummernet.

“The chances that what you’re looking at is a Ruby-throat is about 50/50, because there are western species that start showing up.”

He says you might get a chance to see a Rufous hummingbird.

“I kind of think of these little birds as each one has certain superpowers, and the Ruby-throat’s superpower is that it’s the smallest bird that can fly across the Gulf of Mexico nonstop. Now the Rufous hummingbird’s superpower is that it’s very cold tolerant. So there are many of these birds that have stayed around in Michigan and Ohio until January and then they move on.”

He says the males are a reddish-brown color with a glowing orange throat and a white breast. But the females look a lot like Ruby-throats.

So if you see one, take a picture of it and e-mail to Chartier. He says he’ll identify the bird and use your sighting in his research.

Environmental groups say climate change is the biggest threat in the 21st century to migratory birds in the Great Lakes.

Every year, hundreds of migratory bird species pass through the Great Lakes region.

But a new National Wildlife Federation report says climate change is reducing the range that these birds need to survive the journey.

The report says climate change is affecting where migratory birds can feed and raise their young.
