Tonight, Barbara and I found 3 Dickcissels and 2 Henslow's Sparrows at Wilson Prairie. Wilson Prairie is private property located near the Stephenson County line west of Pecatonica. We were there on a private tour. The Henslow's Sparrows were calling from a CRP site immediately east of Wilson Prairie. Also calling were Vesper, Grasshopper and Field Sparrows, and Eastern Meadowlarks. A large owl, probably a Great Horned, flew out of the treeline about 30 minutes after sunset.
