I think that this is a long billed dowitcher but I never heard it call so I am not sure.
Similar in size to killdeer, identified by call.
Found roosting at our campground, basically the only interesting bird that we had there (although Botteri's Sparrow was nice). Snapped a few photos and then left it alone.
Perched on roadside fencepost.
Blind Souris Valley roadside.
