Rock Cut State Park

Leave a comment

Rock Cut State Park is located northeast of Rockford.  It is bisected by I-90.  A convenient exit is located at the intersection of I-90 and IL 173.  Proceed west from the exit ramp (toll at this spot-no cash, only IPass) to the main entrance off of IL 173.

The entry road will pass through a planted prairie and then into scrubby second growth. This area should be checked for Northern Shrikes in March and sometimes Loggerhead Shrikes in late March/early April. The shrikes are often in the vicinity of the campground. Turn left at the first stop sign and drive 500 feet to the campground entrance. The loop road is closed beyond the campground entry during the winter, but you can enter the campground.  Once the roads are cleared of snow, the gates are often opened and the full loop road can be accessed. On the entry road into the campground, look for a variety of sparrow species, particularly Fox, Song, American Tree and juncos.  n early Hermit Thrush might be in their company.

Once you check the campground, retrace your path back to the stop sign intersection on the loop road and turn left toward Pierce Lake. The road will pass through upland hardwood forest which is pretty empty of birds during winter, so keep going to the parking lot by the dam at the west end of Pierce Lake. The deepest part of the lake is just east of the dam. Check the open water on the lake. If the lake is open, there are several other spots to check for waterfowl, including the Red Oak picnic area. Continue on the loop road across the dam and follow it past the concession stand to the driveway to Red Oak. Park at the end of the lot up on the hill and walk down toward the lake for the best views.

The Olson Annex to Rock Cut SP is located on the east side of I-90. You can cross over I-90 on a small bridge from the main loop road and, at the stop sign, turn left toward the beach area. Olson Lake is much more shallow than Pierce Lake, and it freezes deeper, so it is later to open in the spring. Diving ducks are usually at the western end, near the dam/spillway, while the east end has puddle ducks.

Bend of the Little Calumet River

Leave a comment

This large bend in the Little Calumet River is located roughly between 127th & 130th Streets just to the west of Indiana Avenue in southeast Chicago. Its strategic location (adjacent to clean water outflow from the Calumet Water Reclamation Plant, as well as warm water outflow from steel industry across the river in Riverdale) makes it a magnet for wintering waterfowl and wintering waterbirds in general. When other rivers and lakes freeze up during cold winters, the Bend invariably remains open due to warm water outflow, and waterfowl concentrate here in large numbers.

The Bend is best birded from the MWRD SEPA Station #2,  located on the south side of 127th Street about a block west of State Street in Chicago. This area is private property, but MWRD has no objection to birders observing from this location if certain protocols and restrictions are observed. Birders who accept the risks of birding from the SEPA Station #2 viewing platform must notify the MWRD Police Section at 708-588-4035 prior to their visit. Birders are required to park across 127th Street and walk to the SEPA Station grounds (parking is not allowed at the SEPA Station). Keep an eye on your vehicle, as this is not the best of neighborhoods.

Birds found at the Bend from 2002 – 2013 include 25 waterfowl species (22 ducks). Regularly wintering waterfowl include Mute Swan, Gadwall, American Black Duck, Redhead, Ring-necked Duck, Greater Scaup, Lesser Scaup (hundreds), Bufflehead, Common Goldeneye, and Common Merganser. In addition, Tundra Swan, Wood Duck, American Wigeon, Northern Shoveler, Northern Pintail, Canvasback, Ruddy Duck, and all three scoters have also occasionally appeared at the Bend during the winter months. An immature male King Eider found on February 17, 2010 was by far the rarest waterfowl species recorded at this location. Duck hybrids found here have included Gadwall X Mallard, American Black Duck X Mallard, and Mallard X Northern Pintail.

Other regularly wintering waterbirds include Pied-billed Grebe, Double-crested Cormorant, Great Blue Heron, American Coot, and Belted Kingfisher. Black-crowned Night-Herons are far less reliable in winter, but they occasionally do occur. Bald Eagles are occasional during winter (a pair of Bald Eagles built a nest at nearby Mittal Woods in 2004).

Herring Gulls and Ring-billed Gulls (hundreds) regularly winter at this location. Although not particularly noteworthy as a gull location during most years, Bonaparte’s, Thayer’s, Iceland, Glaucous, and Great Black-backed Gull have all been found here during the winter months since 2002.

Elmhurst ComEd Substation

2 Comments

The Elmhurst ComEd Substation is home to DuPage County’s largest Monk Parakeet population. Easily accessible viewing along Parker St, to the west of the fenced-off compound, allows for great looks at the Monk Parakeets which live at or around the compound year round. The northern most transformer outside of the compound holds their large communal nest. The Parakeets may be seen at this nest from March through November. During the winter months, the resourceful birds roost on the heat emitting structures within the Substation compound. In addition to the Monk Parakeets, other species occur in the small retention ponds to the north and southwest of the compound including Wrens and common Sparrow species. Also of interest, the Maywood Gun Club Lake, a private large open water lake producing migrant waterfowl (i.e. Common Goldeneye and Lesser Scaup) is easily viewable from Parker St. just south of the Substation. It is noteworthy that although parking and viewing is possible along County Line Rd. to the east, it is safer to park and walk along the western border on Parker St.

Peoria Lake

2 Comments

Peoria Lake is the large body of water formed by the broadening of the Illinois River between Peoria and East Peoria. It may also be referred to as Lower Peoria Lake to be distinguished from Upper Peoria Lake to the north. It’s deceptively large (approximately 3 miles long and 1.5 miles wide) and you can often be looking across as much as 2 miles of open water. Fortunately there are several publicly accessible locations from which to view it. Peoria Lake is a natural migratory corridor which thousands of ducks and other waterbirds use. It is especially productive for diving ducks from November through March. Large numbers of Lesser Scaup, Ruddy Duck, and Canvasback rest and feed here during migration. It’s also good for Bufflehead, Redhead and Ring-necked Duck. Common Goldeneye and Common Merganser are regular winter residents. It’s a one of the best places in the area to look for scoters and other uncommon diving ducks. It’s good for loons and grebes as well.

The strip of woods between Cooper Park South which starts behind Jonah’s Seafood House and extends north of the Carl Spindler Campground to the McCluggage bridge can be very good for migrant landbirds. There is a nice trail system and boardwalks through the area.

East Port Marina is a good area to check for gulls. They like to congregate and loaf on the piers. Jonah’s often throws out old dinner rolls which attracts Ring-billed Gulls and occasionally bigger gulls will come in as well. Herring Gull is common here and Glaucous Gull has been a rare but regular visitor in recent winters. Lesser Black-backed, Thayer’s, Iceland, California, Franklin’s, and Bonaparte’s have all been found here. I’ve seen reports of Sabine’s Gull on Peoria Lake as well, but have never seen or heard of one roosting at East Port Marina.

Here is map of Peoria Lake with some of the better birding spots.

Almond Marsh

Leave a comment

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.
