First, thanks to Tuck Russell and Dan Jehl for helping me locate this birds. We were joined by about 5 other birders at the N.W. sod almost directly out from the buildings near Dairy Mart Rd. The sandpiper continued feeding with Killdeer. It eventually flew South. I relocated the bird with other Killdeer at the N.E. sod. The bird does not seem in any hurry to leave. Great observations of the bird and a few acceptable photos. The bird was still present when I left around 0845 am.
