Almond Marsh

Located in Northern Lake County, Almond Marsh is an active heron colony and is a part of the Lake County Forest Preserve District. In spring and summer, roosting birds include Great Blue Heron, Double-crested Cormorant, and the only reliable spot to find Black-crowned Night Heron in Lake County throughout the summer months.   Post-breeding wanderers are also a highlight and something to look for at Almond Marsh in season.  Records have included Snowy Egret, Little Blue Heron and Neotropic Cormorant.

Besides the rookery, the main attraction is the open water.  During migration, one can find Horned Grebe, American Black Duck, Gadwall, American Wigeon, Northern Shoveler, Green-winged Teal, Redhead, Ring-necked Duck, Lesser Scaup, Bufflehead and Ruddy Duck.  Breeding waterfowl seen here include Pied-billed Grebe, Wood Duck, Mallard, Blue-winged Teal and Hooded Merganser.   Other marsh breeders include Green Heron, Sora, and Virginia Rail.  By the entrance gate there can be Woodcocks “peenting” in early spring.   In past years, this has been a reliable spot for Yellow-headed Blackbird and Red-headed Woodpecker.  Common Gallinule is also a sporadic breeder.  Both Red-tailed Hawk and Cooper’s Hawk have bred on the preserve, as well as Great Horned Owls.

The oaks surrounding the marsh are a good place to look for spring migrants as they begin to bud, and most regular migrants have been seen.

Rollins Savanna

The marshy sloughs can be accessed from either the Washington St. parking area on the south, or the Drury Lane parking lot on the west (shorter walk from Drury Ln.) Birds breeding here include Yellow-headed Blackbird, American and Least Bittern, Sandhill Crane, Henslow’s, Savannah and Grasshopper Sparrows, Bobolink and other expected prairie species. In the fall, the wet areas around the slough edges can be excellent for sparrows, especially Nelson’s and Le Conte’s. Short-eared Owls can be seen here in most years from October to December and sometimes through the winter. American Kestrel and Northern Harrier are regulars during winter and during spring and fall, the ponds at Rollins are loaded with all manner of dabbling ducks. It’s the best spot in the area for Northern Pintail. In winter it is not unusual to get Lapland longspur, Horned Lark, and Snow Bunting here as well.

Hennepin & Hopper Lakes

Hennepin-Hopper, as it’s known, is one of Illinois premier birding locations. This restored wetland has some of the best quality cattail marshes in northern Illinois.

There are 3 primary birding spots here:

The boat launch
The boat launch area offers a good vantage point to scope the marsh. Breeding birds here include Yellow-headed Blackbird, Common Gallinule, Least Bittern, American Bittern, Swamp Sparrow, Marsh Wren and other expected marsh species, such as Sora and Virginia Rail. King Rails were calling here in May/June of 2011. Bald Eagle is frequently seen here. In the woods to the south, Red-headed Woodpecker and Carolina Wren are resident. In March and April, thousands of waterfowl congregate here, and White-fronted Goose and Cackling Goose are usually present.

The tower 
The tower offers an elevated overview of the marshes, and many of the same birds. Looking north, one can often spot Northern Harrier, and Sedge Wren nests in the prairie around the tower.

Urnikis Rd.
Another access point, and usually the best for Yellow-headed Blackbird. If the water is low, the gravel trail can be walked for quite a distance through the marsh and out into the prairie to the west. Henslow’s and Grasshopper Sparrows breed here, but the trail is most often under more than 2 feet of water. To access this spot turn west off Rte. 26 at Urnikis Rd. (780E). This is about 1/2 mile north of the main entrance road (795E). Note that there is only room to pull in one or two cars and that the open area that looks like a small parking lot, on the left as you pull in, is private property.

The marshes at Hennepin-Hopper have produced a lot of rare birds including Black-bellied Whistling Duck, Great-tailed Grackle, Ross’ Goose, White-faced Ibis, Black-necked Stilt and Hudsonian Godwit.
