White-rumped/Baird's? Sandpipers in Southern Ontario (1 Viewer)

[osbirder]

I took pictures of some sandpipers I saw in an inland location beside a river in Southern Ontario on May 25. I thought they were all "peeps", and one was obviously larger and appeared to have wings longer than the tail. The picture isn't all that clear. Photo #1 and Photo #2 (larger bird near center of photo).

I went back to this same location on May 29, and saw only 2 sandpipers, but again one was larger with longer wings than the tail. This one had streaks along the sides as well. I think it is a White-rumped Sandpiper. Photo #3.

I'm not sure if the first bird could be the same one as on May 29 or a different one (I don't particularly see the side streaks) but the photo isn't that clear.

Can anyone tell the definite ID's for these 2 birds?

#3 is certainly a White-rumped Sandpiper.

Thank you for the confirmation on the White-rumped Sandpiper.

The other one is difficult to tell. It may or may not be the same bird. Does anyone else have any thoughts?

I think all of your birds in question are White-rumped. In the first two pictures, I would expect to see at least a little buff coloration and maybe a less upright posture for Baird's. The third image is a clear-cut White-rumped with those marks on the flanks.

Thank you very much.
