Well, Merlin Photo ID thinks its a Meadow Pipit anyway, which if it is, it's the first time I've knowingly photoed one.

I'm afraid I was mostly trusting Merlin, which only offered Meadow. Looking up the difference between the two in a book, they are very similar, and I'm not familiar with them - Merlin perhaps went by eye markings or side streaks, or perhaps balance of probabilities based on time of year/location (Tree Pipits being rarer).
P.S. I've not knowingly photoed a Tree Pipit either!
