Note: This gull lingered at the Riverlands EDA, St. Charles County, MO into March 1997. The range of dates in MJIB (8:2:57)
includes mostly Missouri data. The early date of January 30 in Missouri is in retrospect to the February 6 verification.
JVB was in communication with DMK and aware of the February 3 sighting in Illinois when he made his ID on February 6.
Illinois data prior to February 3 and beyond February 9, 1997 is lacking.

February 19-20, 1993, Macon County (Myrna Deaton, Richard Palmer) (MJIB 2:3:112)
