Taken on Christmas Day in the San Francisco Bay Area in reddish late afternoon light. I'm pretty sure the bird on the right is a Least Sandpiper (yellow legs, white belly, tiny size). The other two I'm not sure. There were dowitchers nearby and these two were considerably smaller than the dowitchers, but obviously larger than the bird I think is a Least Sandpiper. Any ID help would be most appreciated.
Agree with Dan, just to add that the bird on the right has more textured
plumage (dark stripe mid feather) than the plain plumage on the two on the left.
Good ID key.
