Nachusa Grassland

Leave a comment

Nachusa Grassland is a huge area of high-quality sand-hill prairie with many desirable breeding and wintering species. Grasshopper Sparrow, Henslow’s Sparrow, Savanna Sparrow, Vesper Sparrow, Sedge Wren, Bobolink, Horned Lark are all easily found breeding species. Look and listen for Lark Sparrows along the sandy two-track that goes west from the visitor center. Other sandy-scrub loving species such as Orchard Oriole, Bell’s Vireo, White-eyed Vireo, Blue Grosbeak and Yellow-breasted Chat can be found along this and other trails with appropriate habitat. Look for Willow Flycatcher in the wet areas.

The woods at the west end of Stone Barn Road have had breeding Hooded Warbler. During migrations, the edges along Stone Barn can be excellent for migrating sparrows, which have included Harris’, Le Conte’s and Eurasian Tree. Wintering raptors include Short-eared Owl, Rough-legged Hawk and Northern Harrier. Golden Eagle and Prairie Falcon have been seen in the area regularly during winter, often located by driving the roads to the north and east of the visitor center. Wild Turkey and Ring-necked Pheasant can usually be found along the back-roads in winter, and pheasant can usually be heard almost anywhere during spring and summer.

Chautauqua NWR

Chautauqua National Wildlife Refuge is well known to Illinois birders for waterfowl and shorebird concentrations. The water in the various pools is regulated, and if dropped at the right time of year the habitat can be outstanding for shorebirds. Even if the water levels are fairly high, there are usually mudflats in the SW corner of the upper pool (north of the crossdike). There is a small island and usually mudflats in the NE corner, viewable from the dike at Goofy Ridge. There are parking lots and trail access at the east end of each dike.

In season, and when proper habitat is present, this can be the best place in Illinois to find large shorebirds such as American Avocet, Marbled Godwit, Hudsonian Godwit. Red-necked Phalarope and Wilson’s Phalarope have been found here in numbers some years. Very rare vagrants that have been seen here include Ruff, Sharp-tailed Sandpiper and Curlew Sandpiper. Gulls also concentrate here, and Franklin’s, Sabines, Little, Lesser Black-backed have been recorded at Chautauqua. The south pool can have tens of thousands of waterfowl during migrations and is one of the best places in the state to see large numbers of Greater White-fronted Goose, Cackling Goose and Northern Pintail.

The area around the headquarters can be very good for migrating land birds, and there is an observation tower where you can get a good view of the south pool. The woods around the Goofy Ridge access can also be very good during migrations. Breeding birds here include Red-headed Woodpecker, Eastern Screech Owl, White-eyed Vireo, Yellow-billed Cuckoo and Eurasian Tree Sparrow.

Thompson Lake is one of the magical birding spots in Illinois. The number of rarities and unusual species found here in recent years is too big to list here. Breeding or summering species include up to 16 species of ducks and geese, Black-necked Stilt, Black Tern, American White Pelican, Common Gallinule, Cattle Egret, Black-crowned Night Heron, Snowy Egret, Little Blue Heron, American Bittern, Least Bittern, Sora, Virginia Rail, King Rail, Marsh Wren, Northern Harrier, Bald Eagle.

Shorebird numbers depend on the water levels. During migrations Thompson Lake is an excellent place to look for unusual shorebirds including American Avocet, Marbled Godwit, Hudsonian Godwit, Willet, Piping Plover, Western Sandpiper, Sanderling (always difficult to find away from Lake Michigan), Red-necked and Wilson’s Phalaropes. Franklin’s Gulls can usually be found here dring spring and fall migration, along with Common, Forster’s and Caspian Terns. White-faced Ibis have been seen here regularly, especially in fall. The scrub and weeds south of the observation tower can be very good for sparrows and other migrants September—November, including LeConte’s Sparrow, Nelson’s Sparrow, Sedge Wren. After breeding, hundreds of Eurasian Tree Sparrows often congregate near the observation platform.

In November and December Hundreds of thousands of waterfowl rest at Thompson, and flocks of 10,000 or more Snow Geese are frequently encountered. Ross’ Goose, Greater White-fronted Goose and Cackling Goose can usually be found here as well.

At the Clark Rd. hunter’s access, many scrub and prairie species can be found, including Henslow’s Sparrow, Yellow-breasted Chat, White-eyed Vireo, Bell’s Vireo, Willow Flycatcher, Red-headed Woodpecker. Walking the half-mile trail to the water’s edge can often be very productive. Note that the access is simply a mowed path in the grass, and may not be accessible to all vehicles.
