I went back to Sabattus River the next day after shooting the running water the evening before. I wanted to get more photos of compositions that I didn’t get a chance to do because the sun had set and I ran out of light, I could not see to focus. While I was shooting the running water this sandpiper showed up so I put on my telephoto lens and snapped some shots while it was foraging for food. I’m pretty sure it’s a sandpiper, I looked in the field guide to try to positively identify it but I saw no photos that were an exact match. It may be a juvenile.
