Chris and Geoff Williamson led a nature walk to La Bagh Woods Forest Preserve along the Chicago River near where the Edens Expressway crosses Foster Avenue. The outing was sponsored by the Chicago Ornithological Society and the Chicago Group of the Sierra Club. The weather was a nice 64 degrees Fahrenheit, with east winds at 5 mph and cloudy skies. Toward the end of the outing some rain showers moved in and we were sprinkled on.

When all was said an done, we had observed 34 species of birds, 3 species mammals (aside from human beings and domestic dogs), 1 amphibian species, and 1 damselfly. Lists of those species along with the number observed are provided at the end of this report.

See list of species below and more photos on Geoff's website.
