June 8, 2013: Tree Swallow Study

Anyone that has hiked along the Upland Trail will have noticed the Tree Swallow nesting boxes located below the trail in the northwest corner.  Carol and Dave Vleck (ISU) have been conducting a study on this species for several years.  (They have given a presentation to the Friends group in the past.)  One photo shows Carol measuring the wing length of a female.  The other photo shows Carol weighing the same bird, with her sister, Susan Masters, recording the notes.  The Vlecks are retiring and will be passing the "baton" on to someone else to continue the study.  6/8/13 (Wolf.
