Was surprised to see a group of 28 White-rumped Sandpipers here: 40.197274,-109.727561 They were in breeding plumage with decurved bills and could see reddish near base of lower mandible on some birds. The tips of the primaries extended past tail. They had streaked chest and flanks and could see a light rufous cap on some birds. Overall white, rufous, and grayish. Black legs. Was able to get some photos.
