This female Tree Swallow was found on the Upland Trail, just west of Jensen Pond, picking at insects amongst the gravel. Note the band on her right leg. She is probably part of the ISU study that has been conducted for several years. The nesting boxes found below the Upland trail (northwest corner) are part of the study. The males have a more metallic blue color to the upper parts. 5/15/13 (Wolf. Oesterreich)Monday, May 20, 2013
