I was on Cape Cod MA last week, and had a flock of these quick little shore birds make multiple passes up and down the beach while I enjoyed some morning coffee and sounds of the shore. Been trying to ID them, but pretty confused. At first I thought black bellied plovers in non-mating plumage, but the bill seems to short. I'm now thinking Dunlin or Least Sandpiper. I would appreciate confirmation or correction. CC is also welcome.
