Tennessee sandpiper (ID?)

After looking through dozens of shots of sandpipers and their relatives, I feel like I've been on a snipe hunt. Any help in ID'ing it would be appreciated.

Saw this little bird at the river park Friday.

Thanks, Bob, Gary and George for the comments and ID. From what I read this must be the breeding plumage. It did typically bob its tail as it walked. Perhaps this is the female, and the male is guarding a nest.

First image works for me and this species is pretty skitish in my experience. Noy sure jkust what it's on though...thought aligator for a second

It's some kind of tough plastic mesh to prevent further erosion of the bank.
The bird was startled at first and flew. The second time I saw it, it let me get within 10-15 feet (about 3-5 meters). I'm still amazed that we have sandpipers here, but they are listed as having bred in state.
