Well, it's some kinda Plover, maybe a Mountain Plover. The problem with Plovers is they change coloring from winter to summer and it makes them hard to identify, especially when they're changing (hard for me, anyway).
Dang, wish I had seen this topic sooner. I think I may have had a chance.
There's actually a lot of vegetation there for it to have mountain plovers.

More than 20 landowners have signed agreements this year to support ongoing state and federal efforts to conserve mountain plovers, small, insect-eating birds that nest on fallow, and freshly cultivated farmland on Colorado’s Eastern Plains.
The landowners have inked voluntary memorandums of agreement in support of the state’s mountain plover conservation effort, an important part of Colorado’s ambitious, long-term Conservation Plan for Grassland Species.
