For those that don't know about the oyster balls, through a scope they kind of look like big rubbery rough ball shaped things with big holes in them. I think they may be made of concrete, but when viewing them from a distance they don't look like concrete. There are five of them. They sit in the water, but may be covered during a higher high tide. The bird then disappeared behind and below the berm for quite some time and then Ron Wilson spotted it a ways out to the right of the oyster balls up against tall grass, behind where a bigger pile of rocks were at the water's edge (where the rocks appear related to water will depend on tide). At the time there were five Gulls on the sand in that area. It was pretty far away, but still findable in a scope with effort. It moved back and forth along the edge of the tall grass for a while.

Near the right side of the semi circle is a shorter right leaning rusty looking post with some large bumpy looking things at the base. The post was shorter than some of the others. It would wander away from that spot in both directions and then return. When it decided to run it moved fast. At one point it also went to the left of a high section of sand/dirt that casts a big shadow. Sometimes it went into the rocks. It is extremely difficult to spot when it does that. When I left I think it was still in the semi circle of sand.

At some angles the red is not visible, but if it's facing you or facing sideways it is. It appeared larger than the Semi-palmateds. There were also Black-bellied Plovers and other shorebirds. I heard there was a Ruddy Turnstone also in the area, which could confuse things.

Looking way over to the mud that's now being exposed right behind and to the right of the oyster balls. The infamous oyster balls where the white-wing tern would sit last summer.
