Based on structure (long legs, relatively slender bill) and some aspects of plumage (heavily marked upperparts, obvious malar), these are juvenile Richard's Pipits - see my comments on the other recent thread concerning these two species. The heavily 'scalloped' upperparts indicate that they are juvenile birds.
I actually find that Upland Pipit can be a very difficult bird to see, especially to see well. It is more skulking than most pipits, disappearing into the mountain grassland, and only really seems to show well when singing from rocks.
