In the early 1800s, a large part of northwestern Ohio was an impenetrable swamp, inhabited only by a small number of Indians and a few hardy settlers. Somewhere along the way this 12-county area became known as the Great Black Swamp, known for its mosquitoes and a dreaded summertime disease called swamp fever. By mid-century it had mostly been drained and turned into farmland though, and all that remains of it now are the marshes of Lucas and Ottawa counties: Magee Marsh, Metzger Marsh, and Ottawa National Wildlife Refuge.

If the Great Black Swamp was still in existence today it probably would be a nature preserve and wildlife refuge similar to the Everglades in Florida. (– Jim Mollenkopf, in his book The Great Black Swamp)

Thankfully, I’ve got the 21st century form of swamp fever. The primary symptom is an insatiable desire to roam the marshes, woodlands, and meadows, watching hundreds of species of birds migrating through. The fever also causes a person to become blinded to virtually everything else for weeks at a time: household chores are ignored, as are friends and family–unless those friends and family are also afflicted with the fever. Everyone knows the fever is much more fun when you can share it with others.

Those who suffer from the modern version of swamp fever recognize fellow sufferers by their attire, which looks like this:

I’m actually deliriously happy to have this particular affliction. I just wish it could last a while longer.

The photos shared here were taken in the marshes of northwest Ohio in the past couple of weeks. On Friday I’ll be heading back down there for 10 glorious days in the “Warbler Capital of the World.” I’ll be doing some volunteer work for the Biggest Week in American Birding, catching up with friends from across the country, and trying to see as many beautiful birds as I can in this all-too-brief period of time.

Did you notice my cute little BSBO hat? (BSBO stands for Black Swamp Bird Observatory — aren’t you glad you know where their name came from now?) I usually hate wearing hats, so I was thrilled to find this new style in their gift shop yesterday. I think it looks like a conductor’s hat instead of a baseball cap. And within 15 minutes of putting it on, a total stranger yelled across the parking lot at Magee Marsh to tell me he liked my hat…proof that it’s a keeper.

I hope you enjoyed these photos, and I also hope I’ll have many more to share with you very soon. Even if you’re not lucky enough to live near the Great Black Swamp, make sure you still keep your eyes peeled in your neighborhood–you never know who might use your yard as a migration rest stop!
