A group of 17 individuals spent most of the morning of August 18, 2012 walking through Jackson Park's Wooded Island, south of the Museum of Science and Industry, and then back up the east side of the lagoon and through Bob-o-link Meadow. We looked for birds, bugs, and anything that moved.  Below are the lists of birds, insects and animals observed.
