In 30 years, I've never experience something like this. While hunkered down at the water's edge, well over a thousand Dunlin and other sandpipers started making their way towards me. Eventually, all I could hear was a chorus of "peeps" as the birds quickly followed the tide moving in...eventually surrounding me. It was like I was feeding with them at one point. I took a few photos and crawled away, making sure not to flush them on their journey of several thousand miles.
