Pectoral Sandpiper | Illinois Birding by County

ALL OF THE AREAS DESCRIBED BELOW ARE ON PRIVATE PROPERTY, SO DO NOT LEAVE THE ROAD RIGHT-OF-WAY.

Oliver Road runs along the Pecatonica River and feeder streams northwest of Rockford. From IL 75, turn north on Harrison Road and follow it to Oliver Road on the left. After crossing a small stream, the surrounding area opens on to an area of planted prairie grass on the south and a “flood bottom” cornfield on the north. A tree line north of the corn field marks the edge of a stream and the Pecatonica River bottoms. In spring, the corn field is often flooded, and so it is attractive to migrating shorebirds. Species of interest found here are Wilson’s and Red-necked Phalaropes, Willets, Least, Semipalmated, White-rumped, Pectoral, Baird’s, Stilt and Western Sandpipers, several species of plovers, and terns, usually Forster’s, but occasional Black. On the south side of the road, in a small pond surrounded by prairie grass (the pond is visible from your car so you can avoid spooking the birds in it) usually has puddle ducks, a few herons, and, on one spring count, a White-faced Ibis.

About another 1/4 mile down the road is a cattle pasture with an old oxbow. A stand of bur oaks is just behind the oxbow on higher ground. The oxbow runs west to east, then turns north and passes in between stands of old oaks. Bald Eagles are frequently in this area in spring, and the oxbow should be checked for shorebirds and pipits. Flooded fields to the northwest often have small ponds with a lot of waders and ducks (a telescope is necessary).

The road then makes a 90 degree left turn and passes over a small stream that has a beaver dam on the right (west) side. Heck, this stream for Green Heron, Wood Ducks and, in migration, a lot of warblers, particularly on cool days when they are low feeding on insects near the water.

The road comes to a “T” intersection at Knapp Road. By turning right (west) and then left on Eddie Road, you can take Eddie Road back to IL 75.

Though discovered years before, 2012 has seen a rise in interest in the Lake County Fairgrounds as a birding destination. With close proximity to a dump, it is easy to see what makes this spot stand out in the winter months.

The fairgrounds main parking lot is becoming a good destination for winter gulling in Lake County and one of the only reliable Lake County spots outside of Winthrop Harbor that hosts a wide range of species in the winter. As per usual, the dominant species in the parking lot are Herring Gull and Ring-billed Gull. Scattered amongst these species, there have been records of Lesser Black-backed Gull, Thayer’s Gull, Iceland (Kumlien’s) Gull, and California Gull.

Just north of the parking lot is a small ponds that many of the gulls travel to for preening and water. This pond in April had a beautiful pair of juvenile Bonaparte’s Gulls that spent the better part of a week feeding there. Besides the gulls, this pond can hold significant amounts of waterfowl. Recorded so far have been, Canada Goose, Cackling Goose, Mallard, Northern Shoveler, Green-winged Teal, Blue-winged Teal, Northern Pintail, Hooded Merganser, Wood Duck, and American Wigeon.

In summer, the pond dried significantly, revealing decent mud flats. Large numbers of Great Egret and Great Blue Heron congregated in late summer and shorebirds seen during fall migration included Lesser Yellowlegs, Greater Yellowlegs, Least Sandpiper, Pectoral Sandpiper, and Spotted Sandpiper. Sora’s have been heard and seen in the cattails.

The gravel parking lot to the west of the pond had summering Horned Larks. In winter, flocks of American Tree Sparrow are common, and on rare occasions, Snow Bunting have been seen and heard. The fairgrounds is also an easy spot to pick up American Kestrel, as a resident pair has been seen here for more than a year.

NOTE: It’s important to know that gull congregations are only great when the water at the pond adjacent to the parking lot is OPEN. If it is frozen, the gulls WON’T congregate in any significant number. The gulls need open water for bathing and preening. This most likely designates this as a great gulling spot early and late in the season.
