What Bird Is That Forum

This photo was taken today in SW Montana. Shore birds are tough for me, and originally I was thinking this was a Semipalmated Sandpiper, but after looking at more photos I'm wondering now if it might be a Bairds. The wing feathers look to extend past the tail feathers. Any input would be greatly appreciated!

I’d lean Bairds

Agreed. Both birds seem like typical Baird's to me.
