Greater Yellowlegs

And that should have been recurved bill, not decurved.

Thanks. I'd go with Greater Yellowlegs based primarily on the bill length and shape in photo 3.

added a few more shots that hopefully help distinguish it

This is a Yellowlegs. It's hard to tell whether it is Greater or Lesser though. To me the bill seems to be just barely 2x the length of the head and appears straight, not slightly decurved. The body doesn't appear to be hefty either so I'm leaning toward Lesser but can't be sure.
