BLYTH'S PIPIT?

Spent all day chasing big boy around the gorse on St Davids Head, thankfully joined by Bob Haycock. Initial thoughts were just big pipit and then it called and it sounded odd. Twenty calls later and it never sounded like a Richard's. I couldn't get my camera till the end of the day and took some shots as it turned up again after an hour's wait. The moulted median covert, hind claw, pointed bill with straightish culmen and general, relatively short-tailed proportions suggest Blyth's to me. Bob and I both thought it had some of the jizz of a small pipit. I have to admit though that I haven't seen Blyth's for many years and would be glad of other opinions. A few images here:
