Maybe my monitor has ultrahigh resolution or something, but I see that the bluebird shows incredibly long primaries (with 7 tips visible), making it a Mountain Bluebird. I don't know how many other passerines in the world have a primary projection this long, but it can't be many. Also, I don't see any rusty in the scapulars or ear coverts; the entire upperside seems clear, pearly gray. The undertail coverts and vent are gleaming white. The flanks are a pale gray with perhaps minute hint of buff; this is fine for Mountain Bluebird.
