I would suggest Upland Pipit because:
- brown instead of olive in colour
- lack of white dot at the back of ear covert which is the key id of Olive-backed Pipit
(here rules out Olive-backed Pipit)
- heavily streaked on back
- posture not as upright as Richard's Pipit
- short bill (key id of Upland Pipit)
This is my own opinion, please feel free to comment.
