We saw lots of Meadow pipits, especially on the central sections of the trail. This one was somewhere near Black Carts - day 4 of our walk. Not posing on Hadrian's Wall, by the way, but on a bit of the ubiquitous field walls - some of them surely built with pilfered Roman wall stones. Why quarry new stones, after all, when somebody has already quarried them for you, stacked them there and then left them? But I think mostly the pilfered stones were used for buildings rather than field walls, as much of the Roman wall was built with neatly squared blocks. Made sense to save those for churches and houses. For field wall, any old stone will do.
