Ornithological Summary

This site was chosen as an IBA because it met the criteria for congregations of migratory birds at a migratory stopover site. The Elsen's Hill section of West DuPage Woods contains an unusually large expanse of hawthorn trees in an open field that are of particular significance to the large numbers of migrant warblers seen there.


Elsen's Hill/West Dupage Woods Forest Preserve is owned by the DuPage County and is operated by the Forest Preserve District.
