Here's another Uppie report.  Yesterday, Barry Martz 
"counted at least 9 upland sandpipers in the field south of Oland Rd from 4th telephone pole on Rt 85 south of intersection with Oland Rd. at around 5:15-5:30 pm time frame, about 40-50 yards out amongst the milkweeds--until 2 emergency vehicles with sirens going got them to move over the rise out of sight. There may have been more."
