We checked quite a lot of large pipits from the Safari car to see whether they are Paddyfield, Blyth's or Richard's, because we surprisingly did not find any Richard's so far on our tour and wanted to add it to the list if they were around. Obviously, Paddyfield was very common (two photos above of this species), but to our surprise, we saw several Blyth's Pipits and not a signle Richard's. Attached are photos of two different individuals of Blyth's. The typical features we checked in the field are visible on the photos, including pale lores (excluding Paddyfield), square-shaped black centers of moulted adult-type median coverts with cream-coloured edge (to exclude Richard's / Paddyfield, see visible in photos above) as well as heavily and uniformly streaked mantle and crown without strong lateral crown stripe (excluding Richard's / Paddyfield). I can't remember whether we ever saw any hindclaw, which is hard and unreliable in the field (better on photos), but we counted 6 Blyth's Pipit on a long safari drive, so across a large area.
