Sorry for the bad photo. Might be two different species, and if that’s the case I’ll make another observation.
Looking to confirm ID on bird at top - Possibly Baird's? It looked a bit larger and paler than the others, but that might just be because it was preening and facing me head-on the whole time I observed it. Least Sandpiper in the foreground.
Saw it clearly close by, then got poor picture
No visible physical injuries. Found on the side of the trail.
Saw at Salt Creek Park Forest Preserve in Wooddale, IL.
