This site is a State Wildlife Area with presumably usual rules for access. The Ruff was on the north shore among several hundred shorebirds of various sizes, associating mostly with Long-billed Dowitchers and Lesser Yellowlegs. The shorebirds were skittish and moving around while a Norther Harrier was hunting in the area. If the bird remains in this location, re-finding it would be challenging since it is far from parking areas and in an area that is obscured by brush and sticks. The walk from the nearest parking area required some bushwhacking.
The bird might be picked out of a crowd because it has a paler head than the other shorebirds. At closer range, the short bill and orange legs can be seen.
