Top 10 Migrations in the U.S.
The Nature Conservancy’s lead scientist Sanjayan explores the Top 10 Migrations in the U.S.
Spring migration provides some of the most memorable visual spectacles in nature: a flock of several hundred sandpipers, wheeling and diving in unison to escape a pursuing peregrine falcon, or trees fairly dripping with brightly colored feathers when thousands of migrating songbirds congregate on Lake Erie’s southern shore.
Know when (and where) to look and you’ll see the animals of the world are in motion again—flying to their summer homes and breeding grounds. The Nature Conservancy is celebrating this annual pageant of nature with a listing of the “Top Five Must-see Migrations” in Ohio.
“Migration is probably the most unifying natural phenomena in the world, bringing together the natural history and conservation issues of states, countries and continents," says James Cole, bird conservation manager for The Nature Conservancy in Ohio. “When you see animals moving en masse, you realize it is not enough to just protect them in your backyard, but all along their extended journey.”

The American golden plover is one of the marathoners of bird migration, making an annual spring journey from the grasslands of southern South America to its breeding grounds in the arctic tundra. On its way, it can be found in huge flocks along Lake Erie’s southern shore, at places like Ottawa National Wildlife Refuge and nearby flooded farm fields. Dunlins, godwits, and dowitchers also can also be seen, just a few of the 47 species of shorebirds that visit Ohio. Many shorebirds can also be seen at the Conservancy’s Kitty Todd Nature Preserve.
In May, there are few places better for bird-watching than Ohio’s Lake Erie shoreline. Magee Marsh State Wildlife Area, identified as one of the top birding locations in the country by Audubon and the American Bird Conservancy, draws millions of migratory songbirds from Central and South America. These tiny, colorful birds congregate on the lake’s southern shore to rest and refuel before attempting the flight across Lake Erie. More than 150 species of songbirds have been seen at Magee Marsh during spring. Not all pass through Ohio and move on, though. The Appalachian forests of southern Ohio are prime nesting grounds for the cerulean warbler and northern parula–birds that can be heard as easily as seen in streamside habitat along Scioto Brush Creek at the Edge of Appalachia Preserve.
The monarch’s 3,000-mile, multi-generational migration make it one of the most fascinating creatures in North America. The spectacle is best observed in autumn, when some have witnessed tens of thousands of the insects amassing on the Canadian side of Lake Erie before crossing in huge flocks on their way south to roosting sites in central Mexico. Monarchs are certainly a sign of late spring, though, as they arrive in large numbers to lay their eggs on milkweed plants. In the fall, look for early successional landscapes with plants still in flower (e.g. asters, goldenrod). For a good chance at spotting these winged migrants, travel to Kitty Todd Preserve.
The tiny bobolink, which weighs little more than an ounce, starts out each spring from the grasslands in Argentina and flies as many as 6,000 miles to reach its nesting grounds—which include grasslands in northern Ohio. Look for its striking breeding plumage and listen for its bubbling song at Killdeer Plains and Big Island Wildlife areas and in pastures throughout northern Ohio. These birds are among those threatened by climate change, according to the 2010 “State of the Birds” report.
Ohio claims only one species of hummingbird--the ruby-throated hummingbird. Weighing no more than a penny, these birds fly to Ohio from winter homes in Central and South America, including a 500 mile non-stop flight over the Gulf of Mexico. If you’d like to see them, hang a nectar feeder in your back yard or plant your yard with native flowering plants, including columbine, cardinal flower or bebalm.
