The Nature Conservancy in Wisconsin Lists State’s Top Must-See Spring Migrations

Top Ten Migrations List Also Released for the Entire United States


MADISON, WI | May 17, 2010

The Nature Conservancy is celebrating this annual pageant of nature with a listing of the “Top Three Must-See Migrations” in Wisconsin. The Conservancy is releasing similar lists in states across the country, and offering a Top 10 list for the entire U.S. at www.Nature.org/migrations.

“The journeys of wild animals are a source of inspiration and remind us that we need to protect nature at both the local and global scale,” said Mary Jean Huston, director of The Nature Conservancy in Wisconsin. “And the most visible spring migrants in Wisconsin are birds.”

“There are many excellent birdwatching locations throughout the state and we’d like to share a few of the best places we know of within the state to see different species of waterfowl, waders and songbirds.”

The Top Three Must-See Spring Migrations for Wisconsin are:

Waterfowl
Ducks and geese are among the earliest of Wisconsin’s spring migrants, and their numbers can be impressive. Wisconsin’s Green Bay is one of the largest freshwater estuaries in the world and is critical habitat for migrating waterfowl. A good place to see these birds is along the wetlands of the Mink River, lands protected and managed by The Nature Conservancy on the Door Peninsula. Redhead, scaup (both greater and lesser), bufflehead and goldeneye are just some of the ducks that visit this area in March and April. A good location to see ducks in southern Wisconsin is Lulu Lake, a Conservancy preserve protecting a pristine kettle lake that attracts waterfowl. To the west, along the border with Minnesota, is the Upper Mississippi River National Wildlife and Fish Refuge that provides important habitat for migrating canvasback in the spring. Nearly one-third of their North American population – 75,000 to 100,000 birds – use Lake Onalaska, a backwater of the Mississippi north of La Crosse, as a springtime staging area.

Waders
Ducks and geese are not the only water birds that return to Wisconsin in the spring. Several wetland preserves provide excellent opportunities for watching wading birds, including the largest and rarest in North America: whooping cranes. Whooping cranes were reintroduced at Necedah National Wildlife Refuge in central Wisconsin in 2001 as part of a national effort to establish additional flocks of these critically endangered birds within their historic range. Cranes raised at Necedah were guided on their first migration to wintering grounds in Florida by biologists piloting an ultralight aircraft alongside the birds. The cranes now return to Wisconsin from Florida every April and May. Other notable wading birds that return to Wisconsin in the spring include sandhill cranes, close cousins to the whoopers, and many kinds of herons. Horicon Marsh in Dodge and Fond du Lac counties is the largest freshwater cattail marsh in the United States and provides important nesting habitat for these birds. Horicon is also well-known for its large numbers of migrating Canada geese in the fall.

Songbirds
Spring means migrating songbirds for many birdwatchers. Among the earliest grassland songbirds to arrive in the state are eastern meadowlarks at preserves like the Conservancy’s Military Ridge Prairie Heritage Area in southwestern Wisconsin. Grassland birds that arrive later in the spring include bobolink, dickcissel and upland sandpiper. Warblers are perhaps the most colorful and varied of Wisconsin’s spring songbird migrants. When and where to look for warblers varies with the timing of the season – warblers eat insects and so depend upon the warm weather that makes their prey abundant. Wooded areas are the best locations for warblers and isolated patches of forest in agricultural areas can concentrate the birds. Baxter’s Hollow is an extensive tract of deep forest in Wisconsin’s Baraboo Hills that provides important nesting habitat and attracts birds that are rare elsewhere in the state, such as worm-eating and hooded warblers. Another good location for watching warblers is Wyalusing State Park that overlooks the confluence of the Mississippi and Wisconsin Rivers. The songbird migration here can be outstanding in May – look for many kinds of warblers, vireos, flycatchers, and others.
