It looks like a Olive-backed Pipit but did not have the right olive colour, the bill is not pink in colour and the blackish marking in the white thoat is very prominent. Most importantly no while spot behind ear coverts.
It has a yellowish bill with darker tip, the grey browish colour and heavily streaked breast and flanks, pinkish legs.
But is this Buff-bellied Pipit? I am not sure
