Mountain vs Western Bluebird immature, Ely, Nevada, USA (1 Viewer)

I am second guessing my identification on these immature bluebirds that like to feed and occasionally drink on my roof. There are usually adults around that watch over the young birds. There were none that I could see in the vicinity. Images taken 21 August 2017 at 1500 pm PDT. There were seven of them. I have images for four. Each single bird in an image is different. The two "less clear" birds are duplicated in the group shot. The bird with more blue, bottom right, was a new one flying over the roof.

Most of them show the very long primaries of Mountain Bluebird and the grayer, less rufous, plumage. I think Westerns would be up in the pinyon juniper zone during breeding, whereas Mountain is in more open country.

I believe that they are mountain bluebirds but the juveniles always throw me off this time of year. Thanks for the assistance.

(The P-J zone is a 1 mile walk from my front door so the Westerns are here as well; just not as frequently this time of year. I usually see the Westerns during more typical migration timing.)
