Spotted Sandpiper

We weren't sure who this was. Maybe a type of sandpiper, plover or sanderling. It stands on logs or the side of the lake and flies close to the water.

Thanks to tib78 for the comment! It's a Spotted Sandpiper. The lack of spots is what was throwing us. But I see in the field guide now that the juveniles lack the breast spots and have a darker bill.
