320. Elsen’s Hill, Winfield, Illinois

The Elsen’s Hill unit of West DuPage Woods Forest Preserve in a western suburb of Chicago is a great place to bird year-round.

I’ve heard it called Warblerville, and the Elsen’s Hill unit of West DuPage Woods Forest Preserve deserves the nickname. A friend once spotted 32 warbler species here in one day. In the spring, the 150-acre preserve, about 40 miles west of Chicago, can be mesmerizing.

It’s worth a visit during other seasons, too. Winter birds find an ample food supply here, especially berries, and lowland forest along the DuPage River provides shelter from bitter winds. Even a snowy day might produce Brown Creeper, Carolina Wren, Fox Sparrow, Hermit Thrush, Yellow-rumped Warbler, and Yellow-bellied Sapsucker. Be alert for Barred Owl as well.

All-time sightings exceed 250 species. One of them, a vagrant Black-throated Gray Warbler in October 2010, still has me shaking my head. The bird stayed for weeks, and I swear that every birder in Chicagoland managed to see it except me! Good memories far outweigh the disappointments, though. Elsen’s delivered my lifer Philadelphia Vireo and my first Connecticut Warbler in the county.

The Elsen’s parking lot is itself is a worthy destination, always capable of producing the bird of the day. A look there and a loop around the nearby front pond is a satisfying birding fix if you are short on time. But good luck trying to peel yourself away. Like all great birding sites, Elsen’s has a knack for turning up special birds and pleasant surprises.
