LISLE
ARBORETUM CHRISTMAS BIRD COUNT
Count Circle Information
The Lisle Arboretum Count Circle is the 15 mile diameter area centered on the intersection of Cass Avenue and 75th Street in Darien (Du Page County). The map of the circle below shows the limits of the count circle and also shows how the circle is broken into six areas. Each area has assigned to it an "Area Coordinator" who oversees the group of birders whose territories are in that area. [Please note that the circle appearing below in black and white is actually only 14 miles in diameter; the circle in color (further below) is accurate. We hope to provide a corrected version of the circle image soon.]
